1. Changing Quality Expectations

To many of today’s Internet users, live streaming has always been a way of life online. Older content producers and consumers know that it’s changed a lot over the years.

In the early days, creating valuable content was the most important and arguably only thing to focus on. People weren’t overly worried about professionalism and video quality. That’s no longer the case. Modern Internet users expect a certain degree of quality, and if they don’t find it, they’ll go elsewhere

Influencers who live stream videos on Instagram, artists who interact with fans on their websites, and advertisers who create content for YouTube all need elive streaming solutions that will allow them to meet their audiences’ expectations

For those new to the game, start by focusing on high-performance video capture and encoding, then keep improving. Audiences will notice.

2. Expectations of Interactive Experiences

Today’s audiences already expect interactive experiences. This live streaming market trend isn’t new. However, the expectations surrounding interactive live streaming experiences continue to change with the times.

Since viewers are no longer satisfied with just watching content, creators have been exploring innovative ways to get their audiences involved.

Some continue to find success with more traditional methods like live polling and Qu0026amp;A sessions. Others are getting more innovative, using interactive games and challenges to make the viewing experience more engaging and immersive.

Interactive streaming is also becoming more popular among advertisers. Recent innovations like shoppable videos and methods for improving customization enhance consumer engagement significantly.

3. Cultural Shift Toward Privacy

On the other end of the spectrum, experts also expect 2024 to bring a shift in how the streaming community views consumer privacy. As users become more aware of how their information gets disseminated and used, there has been increasing pushback

More stringent regulations, including the GDPR and ePrivacy legislation, are already forcing compliance with increased privacy measures. This shift doesn’t mean that advertisers won’t be able to fulfill immersive live streaming expectations, but it does change how they do it.

Popular brands are increasingly reaching out to live streamers with sponsorships. The partnerships formed with celebrities and influencers allow them to target demographics effectively through live streaming without running afoul of regulations or creating a perceived breach of privacy.

4. The Rise of VTubing

Recent changes in how content creators think about interactive experiences aren’t just due to evolving live streaming trends. Technological innovations also contribute to more immersive experiences. They include virtual-reality live streaming, often referred to as VTubing.

For those not in the know, VTubing involves streaming content using a virtual avatar rather than a video image. VTubers often use real-time emotion capture technology to control their avatars, eliminating the bounds of physical limitations and allowing content creators to present their online personas differently.

Last year was the best yet for VTubers, who generated over 1.1B hours watched in 2023. There’s no reason to think the tides will turn on this trend, as more people than ever are embracing it. Much of the trend is likely due to increased popularity and broad acceptance of virtual reality.

As the technology required to support VR and AR streaming continues to improve, it’s also becoming more accessible. Falling prices are attracting more consumers, who then go on to become VR live streaming viewers. They attend virtual concerts, events, and meetings, helping to support the ongoing shift toward VR and AR and increasing the popularity of all forms of VTubing.

As we said at the beginning, the world of live streaming is complex, so it should come as no surprise that the most important trends interact. In this case, virtual reality dramatically changes how live streamers create interactive content.

So far, most VR live streams utilize forms of interactive content similar to those of their more traditional peers. However, VR and AR VTubing create unique opportunities for creative minds. In 2024, expect to see new forms of interactive live streaming leveraged to create connections with viewers, increase attendance at virtual events, and promote products.

5. Greater Attendance at Special Events

Special events hosted by live streamers are becoming more popular. In 2023, they constituted some of the most-watched content on YouTube Live, Twitch, and Kick. Examples of this trend include Ibai’s La Veleda Del Ano 3, WestCol’s Stream Fighters 2, and Squeezie’s GP Explorer 2.

Each of these live streaming special events set new records for peak views on at least one platform. However, that’s not the most important thing to watch when it comes to changing industry trends. People watching market trends are more interested in their year-on-year growth, which has been impressive.

High-value brands are taking notice. They are beginning to sponsor not just individual live streamers or influencers but specific events. Ibai’s boxing event is a fantastic example of this. The first virtual event, held in 2021, had a few minor sponsors, JD Sports and Everlast. In 2023, the third event was sponsored by big names like PlayStation, Samsung, Coca-Cola, and others.

Brands paying attention have noticed how effective these VR events are for advertising. As more household names continue to join in as sponsors, the budgets and the aspirations of the live streamers organizing the events should only grow in 2024.rnrnIf there’s one specific sub-sector of VR special events to watch, it’s awards shows. They attracted much attention in 2023, and experts believe viewership will only rise in 2024. This trend is good news for content creators, who organize virtual events and have the opportunity to reach new audiences by winning prizes.

6. Niche Communities Are Picking Up Steam

As live streaming becomes more popular and goes mainstream, niche communities, and micro-influencers are starting to gain steam. This may seem contradictory, but the rise of influencer culture, brand sponsorships, special events, and other major industry changes that draw in new viewers and consolidate existing audiences has propelled them forward

Content creators who focus on niche audiences can cater to small, specialized online communities with specific interests instead of trying to appeal to as many people as possible simultaneously. The creators and micro-influencers who take this approach build deep connections with audiences and create highly engaged, loyal followings.

The pervasiveness of this trend becomes clear when we look at the numbers. The global niche streaming market saw a 27.4% CAGR in 2023, and recently, 82% of Gen Z viewers indicated that they specifically seek out niche communities with personalized content.

In some cases, these niche live streaming communities exist as part of larger, more mainstream platforms. Others take things one step further and seek out or create niche, entirely separate video platforms. Either way, it creates opportunities for content creators who are just getting started and haven’t yet found ways to reach wider audiences.

7. More Tools for Multistreaming

Multistreaming is nothing new. Content creators have been diversifying their live streaming presence across platforms for years. They often stream on YouTube, Facebook, Instagram, Twitch, and Kick simultaneously, allowing them to reach broader audiences to maximize exposure.

Even as other trends like niche live streams and micro-influencing continue to gain steam, u003ca href=”https://www.epiphan.com/blog/how-to-multistream/”>multistreaming> is becoming more popular. Of course, part of the reason this trend is still evolving is that constantly new platforms are coming out that either cater to live streaming specifically or incorporate it into other forms of content creation

Part of the reason that more live streamers than ever are multistreaming is also that established platforms continue to offer more tools and integrations that streamline the process. In years past, it used to be a challenge to manage multiple streams simultaneously. Now, as long as content creators have the right hardware and software to do so, they can multistream much more efficiently.

8. Global Markets Are Shifting

More traditional forms of live streaming, including virtual events and interactive streaming, that use standard equipment, have been popular the world over for long enough that every region has its share of creators and influencers. However, the global markets are still shifting in two ways that are important to watch.

The first is that platform availability is changing where the world’s most popular live streamers are doing business. Twitch pulling out of South Korea is a perfect example. When Twitch announced at the end of 2023 that they would cease all operations in the country due to prohibitively high network fees in February 2024, 19 of the top 20 most-watched VTubers were based on the platform.

These creators are independent. They are not affiliated with agencies or brands. At the beginning of the year, they all had to decide which platforms to use as Twitch shut down. Most opted for YouTube Live, AfreecaTV, or the new South Korean platform CHZZK. This influx of content creators and viewers changed the global live streaming landscape

The second way that the global live streaming scene is changing is that some nations’ live streaming sectors are growing while others are falling. China, specifically, appears slated to make big moves in 2024.

Viewers from different regions of the world have unique tastes. In Southeast Asia, the most watched streams are represented by the mobile gaming industry.

China is not the only country with a growing mobile gaming live streaming sector. In 2023, Battlegrounds Mobile India generated 34% more hours watched on YouTube Gaming than it had in 2022, and that trend is set to continue.

9. Evolving Use of AI

Artificial intelligence became popular in the live streaming industry last year. Content creators had already been using assistant bots and media creators. The difference is that now, AI streamers are gaining popularity

Vedal987 is a great example. Also known as Neuro-sama, the AI streamer generated 5.38M hours watched in 2023. The AI can interact with viewers through chat, react to their submitted photos, and create an immersive experience.

Currently, AI streamers are the exception rather than the rule. The primary role of AI in the live streaming industry is as chatbots associated with human live streaming personalities. The bots perfect themselves over time and effectively moderate chats without altering content creators’ brands.

Many industry observers believe that AI will take on a new role in 2024, further increasing the popularity of VTubing. AI can create VTubing avatars for far less than it costs to purchase the expensive 3D models and rigging setups currently used by the most popular VTubers

Because AI is constantly evolving, there’s no way to know how it will be used by the end of 2024. What’s clear is that AI is here to stay and content creators are already finding new and innovative ways to incorporate it into their brands.

1. Determine the Goal of the Live Stream

What do you hope to accomplish with this broadcast? Do you want to bring in new viewers or generate additional leads? Having a goal in mind simplifies the planning process. To boost sales, the live stream might launch a new product or service. To grow the audience, the broadcast could share breaking news in the industry. A well-planned broadcast is easy to repurpose after the event as demand-gen content.

2. Select a Topic

Narrow the options to a single topic the broadcast will cover. Determine what the message of the broadcast should be. When you know the topic thoroughly, you can speak knowledgeably. Your confidence when doing so will come across in the broadcast.

Focusing on one theme allows viewers to associate with the topic. Keep a narrow focus throughout the event. This focus allows you to showcase your expertise and thought leadership. The audience will feel as if they gain value from participating in the live stream.

Determine the format of the live stream. Some topics are well-suited for question-and-answer sessions. When launching a new product, you might do a reveal or a how-to video. Interviews and behind-the-scenes broadcasts also draw people in.

3. Hire a Crew

Many people do live streams on their own using nothing more than a mobile device. These productions typically are of low quality and don’t present a professional image. Don’t make this mistake. Hire a crew to help you produce a quality live stream that attracts viewers for the right reasons.

The crew may engage with viewers throughout the event, man cameras, help with product how-to videos, and more.

At a minimum, spend the money to bring in an event producer and sound technician. Once these individuals are in place, determine if additional crew members are needed. The number of workers required typically correlates with the size of the broadcast.

4. Choose One or More Target Destinations

Some live streams only appear on one marketing channel to increase the fan base on that channel. Other broadcasts appear across multiple platforms and reach a broader audience. Know which channels the target audience prefers to meet them where they are.

Determine when members of the target audience spend most of their time online. Know what barriers exist for these members and how to work around them. Work schedules and time zones are two factors that you need to consider when deciding when to hold the live stream and draw the largest audience.

Experts recommend establishing a consistent schedule for live streams. Viewers know when to expect new content. This information allows them to plan for future broadcasts and to share these events with others who might also be interested in the content.

5. Invest in Quality Streaming Equipment

Viewers won’t stick around if they cannot see or hear the video. Invest in quality equipment for the streaming event to draw viewers in and keep them engaged. Many people believe the best way to live stream is with a phone or mobile device, as they can broadcast anytime and anywhere. However, a live stream that is of low quality makes them appear unprofessional and ill-prepared. High-quality streaming equipment is an investment in the future, so budget for excellent equipment.

A high-quality camera provides better resolution, but you may have a shaky picture if someone holds the camera during the event. Purchase a tripod to prevent this common problem. Upgrade audio equipment for clear sound, and purchase a lighting scheme that allows everyone to be seen in their best light.

Internet bandwidth also plays a role in a successful live stream. Estimate the number of simultaneous viewers and make certain the bandwidth can handle this volume. Update your device and install video compression software to deliver the broadcast. While it may be easier to grab a phone or mobile device and start shooting, doing so could leave viewers with an unfavorable impression. Avoid this by making high-quality equipment a priority.

6. Consider Multistreaming

A person new to live streaming might use one camera for the entire broadcast. Allow your event to stand out by using multiple cameras to provide different angles throughout the show. Purchase a video switcher to move seamlessly between these devices during the broadcast. Adding logo overlays, subtitles, and other computer inputs into the live stream is effortless with this device.

Multiple microphones or a podium mic add a new level to the broadcast. Invest in an audio mixer to send audio to the video stream. Test this equipment before the event to confirm all pieces work together.

7. Create an Outline

One of the most important live streaming tips a person can receive is to prepare an outline for each broadcast. This outline ensures the event follows a logical order. It also helps the host remember all the points they should cover during the broadcast. Focus on building a framework of points rather than writing a script. The script will sound forced and unnatural, which viewers don’t like.

Increase engagement by offering content that cannot be found elsewhere. Use animations to grab a viewer’s attention. Elements such as these ensure the event is memorable to the viewers.

Many people choose to use a storyboard for this outline. This storyboard helps you visualize the sequence of the broadcast. When creating this storyboard, determine which format to use and create frames for each segment of the live stream. Include talking points and engagement cues to keep viewers engaged. List different shots and angles on this storyboard, along with camera movements and transitions. Make adjustments to the board as needed until you have the perfect outline for the event.

8. Build a Set

Create a backdrop for the event to ensure background elements don’t interfere with the delivery of the desired message. A clean and uncluttered workspace suggests to the viewer that you are in control. The first impression sets the tone for the entire relationship, so make certain the set presents the image you want it to.

9. Test the Connection

Never plan a live stream until you have a stable internet connection. No viewer wants to sit through a live stream that constantly buffers. A stable connection remains one of the biggest challenges for hosts. One of the easiest ways to avoid this challenge is through the use of an ethernet cable and a dedicated connection. No other system will connect to the network and interfere with the event. Test the internet speed before going live on the day of the event using a site such as speedtest.net.

10. Promote the Event

People can only view a live stream when they know it is occurring. Promote the event a few days in advance, using multiple channels to do so. Ask guest speakers to do the same, as they can draw more viewers in. When promoting the event, always share the date and time of the live stream along with where viewers may find it. Tease the topic to generate additional interest.

Post the event regularly on social media and through email marketing. People lead busy lives and these reminders ensure they don’t miss the event. Use a hashtag to make sharing the broadcast easy and create buzz. This hashtag makes it easy for followers to interact with the brand and the live stream. On the day of the event, post reminders and teasers to drive real-time traffic to the live stream.

11. Prepare Guests

Prepare guests before the event to ensure a successful broadcast. Confirm their system meets the basic requirements to join the broadcast and provide a calendar invitation that outlines the steps to join the event. Share a list of topics and questions to be asked, so they know what to expect, and invite them to join a dry run of the event. Ask guests to join the event ten minutes before the broadcast goes live to address any issues and prevent delays.

12. Conduct a Practice Run

A practice run is the equivalent of a dress rehearsal. It provides you with the opportunity to confirm all equipment works correctly and practice your delivery. Use this time to uncover any potential problems and find solutions before the event.

13. Add Graphics

Add titles and graphics to provide viewers with a seamless experience. Incorporate the brand colors and logo to increase brand visibility. However, don’t overwhelm the viewers with text. Limit the use of titles and text to the beginning and end of the live stream. You may also use it to introduce new topics or guest speakers, but keep it to a minimum elsewhere.

14. Countdown to the Event

Viewers may wish to join the stream early to guarantee they don’t miss anything. Other viewers might forget about the event if they don’t receive reminders when the event is quickly nearing. Create a countdown timer to generate excitement, provide a gentle reminder of the live stream start time, and help those who live in other time zones know when to log on to watch. This time may begin several hours before the event, or you might start it 10 or 15 minutes before the event launch time. It is a matter of preference.

15. Engage With Viewers

Establish a system where you can respond to comments during the broadcast. Assign a person to monitor the feed and share questions that will add to the broadcast. This engagement helps you build a strong relationship with listeners and will encourage them to return for future events.

16. Conclude the Live Stream

Many hosts allow the screen to fade to black when the event ends. Don’t waste this valuable time when many viewers remain online and focused on the screen. Use the blank space to share information about yourself, your organization, or the event.

17. Collect Data to Improve Future Live Streams

Select a platform that collects data so you gain insight into what works and what doesn’t. Learn who attends these events and how often they play the content. Are viewers dropping out before the stream ends? If so, where do they leave? Discover how much time they spend watching the video and what device they use when doing so. Certain platforms provide information about which brand device the user is viewing the content on and more.

With this information, you gain a better understanding of the viewers’ interests. Qualifying prospects becomes easier and you can learn what viewers like. Bring this information together to make live video streaming events more successful in the future.

18. Extend the Lifespan of the Live Stream

People might miss the live event because they have prior commitments. Offer replays to get more from the broadcast. You may also take pieces from the broadcast and use them as marketing materials or to tease future events. Pull clips from the event and share them on social media to generate interest in future broadcasts and come up with a sizzle reel to post on your website. One live stream can go a long way when you know how to leverage the material.

19. Request Guest Feedback

Guests play an important role in live streams. They take an active part in making the event a success and can provide insight into what worked for them and what didn’t. Their input provides you with a different perspective on the live stream. Use this information to better meet the needs of guests in the future while improving the overall experience for all.

You must prepare for a live stream thoroughly. Any detail overlooked during the planning stage could lead to an event that is a dismal failure. During this broadcast, you connect with real human beings, and the presentation of this event plays a major role in their perception of you or your organization. Never lower your standards when hosting a live stream. No broadcast is better than a live stream with issues.

What is a One Button Studio?

A One Button Studio is a simplified video recording setup designed to be incredibly user-friendly. As the name suggests, it operates with just one button, making it accessible to educators and students alike, even those without any previous video production experience. The person walks in, presses one button, records their video, and walks out with the recording in hand.

A studio typically includes professional-grade equipment such as cameras, microphones, lighting, and a computer or hardware encoder, all seamlessly integrated into a single, user-friendly interface. The setup also makes collecting the recording simple, whether through automatic file upload to the cloud or a download to a USB drive.

The benefits of One Button Studios extend far beyond mere convenience. The seamless, user-friendly experience puts creative control directly into the hands of educators and students. And because anyone can just go in, press a button, and record content, this saves IT or support staff loads of time.

How One Button Studios are used

One Button Studios have found their way into educational institutions worldwide, enhancing the learning experience in numerous ways:

Flipped classroom and online learning

Faculty and staff use One Button Studios to pre-record lessons for the flipped classroom approach or create entire online courses.

Student presentations

One Button Studios empower students to create high-quality video presentations easily. They can practice class presentations and record speeches, lectures, interviews, or project demonstrations without worrying about the technical intricacies of video production.

Digital storytelling

One Button Studios enable students to explore their creativity by producing videos for storytelling, filmmaking, or documenting school events. This hands-on experience fosters digital literacy and media skills.

How to set up a One Button Studio

Setting up a One Button Studio might seem daunting, but it’s more accessible than you think. Here’s a simplified guide to get you started:

Step 1: Choose a location

It’s best if the studio is located in a quiet space with enough room for your studio equipment and any props or decor you may need for your recordings.

Step 2: Source equipment

You’ll need:

• High-definition camera (with an HDMI or SDI out)
• Professional microphone (shotgun or lavalier)
• A green screen
• Studio lighting
• Epiphan Pearl Mini video production system

Optional: Consider equipping your studio with a busylight to let others know when the studio is in use.

Step 3: Install and configure

Set up the studio equipment (read our “5 steps to creating the ultimate lecture recording studio” article to learn how).

To set up the One-Button part, connect your camera and audio to the Pearl Mini. From there, configure Single Touch recording on the device. You can also configure whether the video gets uploaded to the cloud or downloaded to a flash drive. When the configuration is complete, your users will be able to start and stop the recording by pressing a single button on the Pearl Mini’s touch screen.

Step 4: Create a user guide

To ensure smooth operation, create a user guide for your One Button Studio with simple steps to follow. Include instructions on how to power the equipment, start recording, and access recorded files.

Step 5: Test test test

Bring in students and teachers and test out the setup on them. Take note of friction points and eliminate them. Make sure your setup is easy for everyone to use and produces consistent, high-quality results.

What is NDI video?

Network Device Interface, or NDI®, lets you transmit and receive broadcast-quality, low latency over existing LANs using cost-effective CAT5/6 cables and the quality is virtually lossless.

NDI allows the flexibility to choose from a wider variety of video input sources. Across the same network, you can access multiple cameras, software on computers, mobile devices, and more on the network using a single LAN port. No expensive multiple-port HDMI switches or SDI routers are needed.

The number of NDI sources you can add to your network is practically limitless. To access NDI devices across subnets, you can manually enter the IP address of devices on those other subnets using NDI Access Manager.

With NDI, taking your video production to a different location is a lot simpler without a whole mess of HDMI and SDI cables to manage. All your video sources are readily accessible from anywhere over the network. CAT5/6 cables are also a lot cheaper than traditional SDI or HDMI cables.

NDI and network bandwidth

High Bandwidth NDI, as the name suggests, uses a lot of local bandwidth to share audio and video. This is because the protocol transmits high-quality, low latency, uncompressed video streams that are virtually lossless. Every pixel captured by the camera’s sensors is sent without any reduction – resulting in a lot of data.

Transmitting uncompressed video, especially at higher resolutions, requires at the very least a Gigabit network, though the ideal transfer speeds ultimately depend on the number of concurrent High Bandwidth NDI streams.

A single 1920×1080@30 fps NDI stream needs approximately 100 Mbps of dedicated bandwidth.

The bandwidth required will change, however, depending on the resolution, framerate, and how much motion is being captured by the camera. For example, a 1920×1080@60 fps NDI stream requires 150 Mbps. Meanwhile, a 4K@30 fps NDI stream is roughly 250 Mbps.

It’s recommended to leave approximately 25 percent of headroom so that the signal remains smooth just in case any unexpected network traffic pops up during production.

So, if you have three PTZ cameras sending their video to an Epiphan Pearl-2 at 1920×1080@30 fps, that’ll cost you approximately 300 Mbps of bandwidth. If the Pearl-2 is also outputting the NDI stream in 4K, that puts your bandwidth at 550 Mbps. Reserving 250 Mbps for the suggested headroom, three sources and one output already totals 800 Mbps, just enough for the Gigabit network to handle the transfer

High Bandwidth NDI vs. NDI|HX

There are two variations of NDI to work with: High Bandwidth NDI and NDI|HX.

Both are great options for transmitting video and embedded audio signals across a local network, the main difference between them being compression and latency.

High Bandwidth NDI is uncompressed and requires a lot of bandwidth to transmit. NDI|HX is the high-efficiency alternative, functioning almost exactly the same way but requiring significantly less bandwidth thanks to the advanced compression  – making it an ideal choice for any environment where bandwidth is limited. The high efficiency of NDI|HX will add some latency compared to the High Bandwidth version, but at most, it’s only a frame or two. Audio is uncompressed in both High Bandwidth NDI and NDI|HX.

Here’s how much dedicated bandwidth is recommended for NDI and NDI|HX:

• A single 1920×1080@30 fps High Bandwidth NDI stream needs at least 100 Mbps of dedicated bandwidth
• A single 1920×1080@30 fps NDI|HX stream needs 8 Mbps of dedicated bandwidth

It’s worth noting that these figures are estimates and the actual bandwidth required will vary based on resolution, framerate, and motion.

NDI|HX allows creators to take advantage of almost identical, exceptional quality without worrying so much about bandwidth availability. Of course, the bandwidth available should always be something to consider, but NDI|HX was designed to work over low-bandwidth networks.

Available NDI tools

More and more software applications like Zoom, Microsoft Teams, Skype, NewBlueFX, EasyWorship and others offer native NDI support.

To help spur adoption, there are free NDI plugins for popular applications like VLC and Adobe Creative Cloud. For all the rest, NDI offers simple-to-install free tools. For example, NDI Screen Capture lets you turn a computer into multiple NDI inputs that any other NDI device on the network can access. You can define live video sources like the computer’s webcam, the full-screen display, different windows or combination of windows. Even different software applications running on that computer can be converted into an NDI input.

A couple more options include the NewTek NDI Connect and the NDI|HX Camera app (available for a nominal fee). NewTek Connect makes any camera or device connected to a computer’s capture card (or the local webcam) available to other NDI systems on the LAN. And NDI|HX Camera converts the output from iOS devices and Android phones into NDI video inputs. If you want to take your content further and out onto the WAN, consider using SIENNA Cloud for NDI.

The many free tools and flexible options that are available are definitely helping to drive adoption.

NDI adoption

Adoption of NDI is spreading since its introduction to the public early in 2016. Designing NDI into your AV system is getting easier as more hardware and software options become available. There are also more NDI enabled cameras to choose from companies like PTZOptics, or Panasonic, as well as full-featured video production systems like the Epiphan Pearl-2 that support NDI and NDI|HX. Additionally, Pearl Mini can support up to two NDI|HX inputs, making it a perfect choice to build a small studio.

If you already have existing cameras and AV equipment, NDI is still within your reach. You don’t have to make a huge commitment to switch over all your gear. NDI converters are readily available. These converters connect existing NDI unaware HDMI or SDI video sources to the network – and convert NDI into HDMI signals for your average monitor or video projector. NDI converters range in price and features. For example, the BirdDog Mini offers 1080p60 NDI encoding, 1080p60 NDI decoding, tally, and power over the Ethernet.

Practical NDI applications

Here are some practical ways you can start using NDI.

NDI for live events

Using NDI can offer several advantages when capturing live events such as lectures, conferences, or performances.

NDI eliminates the need for cabling, which can be challenging to set up and manage. By connecting cameras and other devices to an all-in-one production system like the Pearl-2 or Pearl Mini, everything you need to stream or record the live event is acquired in less time and in a much more organized fashion.

If the live event uses presentation software like Microsoft PowerPoint, this can easily be added to the LAN using the free NDI Screen Capture or NDI Screen Capture HX. With this app, the presentation computer becomes another NDI input for your video production system to ingest. It can be added to Pearl-2 or Pearl Mini like any other NDI or NDI|HX source, recorded, streamed, and switched between as needed for the production.

Certain venues won’t have the network bandwidth required for an effective NDI production. It is possible to work around this, however. With NDI Bridge, you can securely connect two entirely different NDI networks from anywhere in the world. This is particularly useful for remote production workflows or transmitting signals to other locations.

Adding remote guests to broadcasts with NDI

Adding a remote guest to a live production was once a tricky proposition. However, with the addition of NDI-out to all major video conferencing apps such as Microsoft Teams, Zoom, and Skype, it’s possible to bring the remote guest’s audio and video to your production tool or system of choice.

When enabling NDI-out on Microsoft Teams, Zoom, and Skype, the feeds can be ingested by Pearl-2, allowing you to switch, record, and stream video with these remote sources as well as any physical input available. Create interesting layouts with NDI inputs using the built-in custom layout editor and add text, custom backgrounds, and transparent images.

NDI and NDI|HX FAQ

Is NDI free?

Yes! NDI is free to use. Costs only come from acquiring the hardware or software licenses. But the ability to access NDI is free.

Should I use a hardware or software encoder with NDI?

While software encoders have advantages, the reliability and performance of hardware encoders make a huge difference when working with NDI.

Software encoding needs computers with state-of-the-art GPUs and ample memory to operate efficiently in an NDI workflow. If the computer doesn’t meet these high standards, it may crash or freeze while trying to process the uncompressed video. Software encoding also has been known to add latency to the NDI feeds.

Hardware NDI encoders, like the Pearl-2 or Pearl Mini, were designed explicitly to encode video, obtaining high-quality video and audio with no additional latency or competing programs.

How do I find my NDI sources?

There are a few ways to find your NDI sources. It depends on the devices being used.

If you’re using an NDI camera, start by logging in to the camera’s interface and making sure NDI is enabled. Once enabled, you can check the stream using NDI Studio Monitor.

The NDI discovery server, available in the NDI Software Developer Kit, can help you find your NDI sources as well. The NDI discovery server automatically discovers NDI sources on the network and provides a list of available sources that can be accessed by authorized users without having to manually search for their exact network location. To make sure each user has the appropriate access to NDI devices on the network, the NDI Access Manager app allows network administrators to set permissions and control access.

How do I connect my NDI sources?

If you’re connecting an NDI source to a Pearl, access the device’s admin panel.

In the Inputs menu, click Add input. The Add input page will open with all available NDI resources listed.

If it’s there, you can press Add and your NDI source will be connected to Pearl. If you don’t see it, enter either the “Group name” if it’s been assigned a group or the IP address of the NDI device in the “Extra source IP addresses” field to discover and receive the signal.

How does NDI transport audio?

Although NDI is commonly associated with video sharing, it can transport both video and audio over networks.

NDI can transport up to 16 channels of uncompressed, high-quality, low latency, 48 kHz, 24-bit audio data in the same stream as video in three ways: embedded audio, analog audio, or digital audio.

The most common way of transporting audio via NDI is by using embedded audio. With embedded audio, the audio data is carried within the video signal, making it easier to keep the audio and video in sync and allowing multiple audio channels to be carried within a single NDI stream.

To transport analog audio via NDI, it must be connected to a physical, NDI-enabled device like a mixing console that converts the analog audio to digital.

Transporting digital audio via NDI can be accomplished with the Audio Direct tool. This set of Virtual Studio Tools (VST) audio plugins allows virtually any audio software to select, receive, and generate multichannel audio.

Wrap up

NDI opens up new opportunities to make your live video production workflow easier and more flexible. You can save money on cables and infrastructure by using the existing Ethernet network and gain easy access to a lot more video sources at broadcast quality. There are free plugins and tools to help you start incorporating NDI into your current AV system right away.

If you’re considering a new AV system and want to start taking advantage of the benefits of NDI, an all-in-one video production system like Pearl-2 makes a lot of sense. Pearl-2 accepts multicast and unicast NDI sources, as well as high-efficiency NDI|HX. Pearl Mini also accepts NDI|HX, allowing to work with any NDI|HX source in low-bandwidth settings.

With Pearl-2 or Pearl Mini, you can bring in video and audio from a multitude of different NDI and NDI|HX sources, such as:

• Remote NDI-enabled PTZ cameras
• Any NDI-unaware HDMI/SDI source using a converter or the free NDI Virtual Input software
• Webcams connected to remote computers using the free NDI Connect application
• Output from iOS and Android mobile devices using the NDI Camera app
• Direct input from NDI-compatible software (Zoom, Microsoft Teams, Skype, EasyWorship, etc)

NDI output from Pearl-2 is recognized as a webcam and is compatible with other NDI applications and devices that support webcams as an input, like Skype and many more.

Network bandwidth

The first step when using NDI is to assess the available bandwidth on your local network. Regardless of the NDI encoder’s make, model, or features, the encoding can only be performed to its full potential if the local network can transport the signals.

At a minimum, the workflow should be running on a Gigabit network – throughput speeds, full duplex ports, and upstream and downstream data speeds must all be capable of transferring the data. Insufficient bandwidth can negatively affect the final product – dropped frames, frozen video, audio glitches, and sudden disconnection.

The general rule of thumb is to reserve 25 percent of bandwidth for headroom so that the signal transmission remains smooth should there be any unaccounted for traffic while your production is underway. So, if a Gigabit network isn’t doing the trick, consider upgrading to a 10 Gigabit network.

A typical High Bandwidth NDI stream at 1920×1080p@30 fps needs approximately 100 Mbps per stream. But the bandwidth required to use NDI effectively will vary depending on the number of video sources, the resolutions, and the frame rates. Ultimately, the bandwidth required is unique to the video production at hand, making it wise to test the network if possible.

In 2016, one year after High Bandwidth NDI was released, a high-efficiency version of the IP-based solution called NDI|HX was released. It was specifically designed to work on low-bandwidth networks.

One 1920×1080p@30 fps NDI|HX stream needs approximately 24 Mbps, making it highly versatile. However, the efficient compression used by NDI|HX does add some latency to the stream. The added latency varies depending on the device, frame rate, and resolution, but it’s typically not more than one or two frames of delay – hardly noticeable to the eye or ear.

NDI and NDI|HX bandwidth recommendations

Hardware over software

When choosing any encoder – and NDI encoders are no different – we always face the same question: hardware or software?

Software encoders have their benefits in certain situations, but the performance and reliability hardware encoders offer compared to software alternatives are essential for an NDI production. Software encoding can be resource-intensive, requiring very powerful computers with state-of-the-art GPUs and plenty of memory to run effectively in an NDI workflow.

Unless one or several computers already meet the requirements of processing NDI’s high-quality, low-latency video, encoding software can crash mid-record or stream. At best, the software encoder will add latency to the NDI feeds, undermining one of the biggest benefits of the solution. Determining a system’s requirements to run an NDI software encoder effectively may be challenging as it can vary depending on the content being produced.

A hardware NDI encoder is an investment in performance and reliability. Optimized from the ground up to encode video, acquiring high-quality and audio inputs with no added latency and no other competing programs makes hardware a wise choice.

Multi-encoding support

Multi-encoding is the process of encoding one or more inputs multiple times with different settings. As a result, you have a wealth of redundancy by capturing all your assets simultaneously at different resolutions, bitrates, and frame rates. For example, you can send a 720p@30 fps live stream to a media server while saving a 1080p@30 fps recording to the device’s internal storage.

Depending on the encoder, multi-encoding support can offer far greater depth than just encoding at different settings. Hardware encoders that feature multiple programs or channels can encode assets independently of the content being shared. For example, if your hardware encoder allows for content to be mixed and switched within the device, you could have several layouts streaming a 720p@30 fps to a media server in one channel, a 1080@30 fps recording saved to internal storage, and ISOs of each video asset recorded in separate channels as additional backups.

This is particularly useful any time you are streaming live events where there are no second chances. Should the stream stutter or fail, you have the recorded backup with its layouts, but you can also work off individual camera feeds to create a produced broadcast.

Input versatility

While NDI has many advantages, keeping your options open and having plan B’s readily available is always a good idea in video production. When searching for an NDI encoder, a device that can accept networked signals and physical cables ensures you can create the best possible video in any circumstance.

When an encoder can accept HDMI, SDI, and NDI or NDI|HX equally, you can stream and record your content regardless of the network’s condition. Plus, you eliminate the need to add converters for any incompatible hardware. But the most significant benefit is that physically connecting certain devices can help keep the network clear to acquire the essential NDI signals with greater reliability. On the other hand, putting every device on the same network could cause network congestion.

Be prepared for any situation with an NDI encoder that works with everything.

Remote device management

An NDI encoder sits at the heart of your workflow. As such, if it’s interrupted in any way, it can grind your video production to a halt.

Whether dealing with a single or several NDI encoders, it’s essential to have the chance to access it from anywhere and mitigate any downtime. Remote device management is an extraordinary asset for any NDI encoder.

By accessing it in the cloud or receiving customized alerts from 24/7 monitoring, you can take corrective action immediately and begin troubleshooting from anywhere.

When a device malfunctions, it’s stressful for all stakeholders. Giving yourself the convenience and flexibility to manage the device remotely in these high-pressure situations is insurance against production interruptions.

Interoperability

On top of delivering high-quality video with greater convenience, NDI’s rise to prominence can also be attributed to its interoperability. As an open standard protocol, it’s publicly available to anyone, allowing any hardware manufacturer to implement it.

When choosing an NDI encoder, selecting a device that shares NDI’s commitment to compatibility will make it a seamless fit in almost any situation.

Integrations with content management systems like Kaltura or automation controls like Creston or Q-SYS can make your productions vastly more efficient and easier to use. Devices with an open API allow owners to customize the hardware to suit their exact needs, further optimizing the exact workflow.

Investing in an NDI encoder that can’t complement the systems already in place, either with built-in integrations or through the open API, can lead to frustration, downtime, and even the complete overhaul of video tech stacks.

To take full advantage of the quality NDI offers, a device that works with virtually everything, like NDI itself, is a huge boon for integrators.

Why hardware encoders are essential

There are two types of encoders: hardware and software.

Hardware encoders offer superior performance and reliability, two key factors that ensure consistent results in streaming and recording professional video. Hardware encoders are specifically designed and optimized to handle multiple high-end audio and video sources without dropping frames or interrupting the stream.

Meanwhile, software encoders run off general-purpose GPUs and CPUs to perform the same function. You need to own one or several computers powerful enough to encode video, or software encoders may be interrupted by background operations. Furthermore, assessing a computer’s requirements can be a long process depending on what kind and how much content is produced.

Rather than constantly evaluating how to optimize one or many computers to work as encoders, hardware encoders have already gone through rigorous tests to ensure the Wowza stream runs smoothly.

Flexible inputs

Audio and video inputs available are the first thing to check in a Wowza hardware encoder. By leveraging a wide range of input options, a hardware encoder can accommodate a variety of equipment you already own – cameras, mixers, and more.

A device that supports HDMI, SDI, and USB all at once means you’ll be able to connect any camera available in any given situation without worrying about easily misplaced adapters. The same is true for audio inputs. A device that supports XLR or RCA stereo means that Wowza can acquire the professional audio gear you need to tell your story.

When you have options to connect your equipment, you can confidently capture the content with whatever’s available. But flexible inputs aren’t limited to physical connections. The rise of hybrid and remote video production means it’s crucial to accommodate remote contributors who may not have access to anything besides video conferencing apps.

A hardware solution that can add remote guests to a production with AV over IP solutions like Network Device Interface (NDI) and Secure Reliable Transport (SRT) opens up a world of possibilities. With the ability to add guests from conferencing tools like Microsoft Teams or Zoom, any space can become a studio, empowering you to create with more flexibility while delivering an exceptional experience to Wowza Video.

Production needs will grow and change over time. There will be new cameras, sound equipment, and ways to bring in remote guests, Prioritizing a flexible hardware encoder for Wowza Video, which already works with everything and continues to adapt to wherever the industry goes next, allows your workflows to adapt to the unique needs of each production.

Streaming protocols

Once a hardware encoder captures the audio and video, it must be transported to the Wowza Video platform. And just like the acquisition of your audio and video, the flexibility with which you can get this content onto Wowza is a massive asset to your content plans.

At the bare minimum, a hardware encoder needs to be able to stream your content to Wowza via the RTMP protocol in H.264, which is easy to find. But Wowza Video supports a wide range of streaming protocols including RTMPS, RTSP, MPEG-DASH, HLS, and SRT.

The best streaming protocol for first-mile delivery to Wowza Video depends on the production. For example, HLS supports up to 4K video and can be delivered across unpredictable networks thanks to its ability to adapt, but it achieves this by adding latency to the stream. Meanwhile, SRT was built to provide low-latency, high-quality video over unreliable Internet connection, making it an ideal choice for any live content that requires real-time communication between talent and audience.

A Wowza hardware encoder that supports multiple different protocols for first-mile delivery so that you can send the possible content for any network conditions, codecs, and type of content.

Cloud and remote management

Whether you plan on streaming from multiple locations or a single studio, accessing one of several Wowza hardware encoders from a single, centralized dashboard makes life easier for all stakeholders.

A hardware encoder configured, monitored, maintained, and operated from anywhere reduces downtime by eliminating legwork or travel time to diagnose the issue interrupting the stream or record.

Ideally, a remote-manageable device includes 24/7 device monitoring and customized alerts, allowing any team member to identify and resolve issues. In addition, remote management should also allow content control, quick configuration, starting and stopping, and the verification that everything is working as intended for the highest quality audience experience.

Remote device access and management offer invaluable peace of mind that the hardware is doing its job to deliver exceptional content to your audience.

Before the hardware was retired, a significant benefit of the Wowza ClearCaster was Cloud Orchestration. This allowed owners to take complete control of an entire fleet from anywhere in the world. Thankfully, many manufacturers have followed suit and it’s possible to find devices that can be accessed, monitored, and controlled in the cloud.

Stream to Wowza with Epiphan Pearl
