How to Broadcast Live Video with Multiple Sources

create live streaming videos

As live streaming becomes more accessible, many users are looking for a way to spice up their broadcasts. It’s easy enough to start using free services and simple equipment, but how can you take things to the next level? This article will look at how to broadcast live video with multiple sources and platforms.

Multi-source live streaming is a great way to boost the production value of your broadcasts. There are many other benefits as well, which we’ll cover here. In addition, we’ll also cover the equipment and software necessary to stream live video with multiple sources, from secure video upload to content delivery to your viewers.

With that in mind, let’s jump right in by considering the advantages of multiple source live streaming.

Benefits of Using Multiple Sources

One of the key benefits of multi-camera live streaming is the availability of low-cost broadcast equipment.

First, let’s take a quick look at the reasons why you may want to use multiple sources for live streaming.

For starters, multi-camera live streams are more professional. They create a higher production value. Switching between multiple camera angles and content sources is the bread-and-butter of professional-grade broadcasters.

TV stations, cable channels, and well-produced internet broadcasts all use multiple sources for better communication and greater aesthetics.

Using multiple sources for streaming also makes it easier to add effects. That’s because you can prepare and test effects on a given source when it’s offline. Meanwhile, another source can be used as the main broadcast source. This gives you more flexibility for editing and adding effects on-the-fly.

However, as mentioned above, there are costs to this. With added complexity comes a greater need for equipment and staff. Still, these costs are well worth it!

Example of Multi-Camera Events in Action

Perhaps one of the best examples of a multi-camera event in action is a sporting championship like the Super Bowl. Super Bowl broadcasts have used multiple cameras for a long time. However, the latest Super Bowls have added many other sources. These include cameras mounted on drones and wires suspended above the stadium.

Those drones (participating in the halftime show) can be seen in this shot:

An event such as Intel’s 500 drones light show used multi-camera live streaming to produce and broadcast live content during the Super Bowl.

Multi-camera shoots are used in news studio settings to provide different angles.

Most studios have at least one camera set for wide shots, one for medium shots, and one for close-ups. A typical news broadcast begins with a medium shot, then switches to a wide shot, which could then be potentially followed by an up-close guest shot.

Multiple cameras and lights are prepared for the production and shooting in a TV studio ready to broadcast.

Both of these examples come from high-end productions with large budgets. However, multi-camera shoots aren’t limited to those with multi-million dollar budgets. Today, the cost of complex multi-camera shoots has plummeted. It’s possible for those even with small budgets to create multi-camera video shoots.

For example, check out the innovative approach in this video below. Here, a small church is using a pair of 4K PTZ (Pan Tilt Zoom) cameras for a master 1080p HD broadcast. This enables them to use digital cropping to get the equivalent of eight camera angles!

Live Streaming Equipment Needs

Let’s discuss some of the live streaming equipment necessary for a multi-source shoot.

1. Multiple Cameras

For a multi-source video shoot, you will need the exact same cameras to ensure consistent color and resolution from all angles.

For a multi-camera shoot, you will obviously need multiple cameras. We recommend that when possible, you use the exact same camera. This provides the same color, resolution, dynamic range, and so on. Using cameras from different manufacturers can cause problems with footage looking different. If you must use different cameras, try to use the same brand.

In some cases, using different cameras will be unavoidable. In this case, be sure to thoroughly test your cameras before using them to ensure they don’t clash horribly with one another.

It is possible to get the look of a multi-source shoot without using multiple cameras. For example, you can use pre-recorded video clips within a live stream. Cutting to these pre-recorded clips mixes up the visual experience. This is a lower cost, simpler alternative to multi-camera shoots.

2. Video Switching Software or Hardware

Video Switching Software
Video switching software or hardware lets you sync video from multiple sources to livestream from multiple camera angles.

The second key when it comes to how to broadcast live video from multiple sources is switching. Switching is essentially the process of selecting which source will be broadcast in a live feed at any given time.

Switchers come in both hardware and software versions.

Hardware switchers tend to be more robust and reliable, but are also more expensive. With a hardware switcher, video sources are connected directly to a panel or rack-mounted unit (usually via SDI or HDMI, sometimes via Ethernet). A display panel is either built-in or connected externally. Buttons on the device allow the operator to switch between sources instantly.

Software switchers are usually integrated into live-streaming applications like OBS Studio, Wirecast, vMix, and others. These applications are installed on a computer, and can then be controlled via a standard mouse and keyboard interface.

Software switchers are more affordable but less robust. Don’t let that discourage you! They can work excellently. However, if you do use a software switcher, make sure you install it on a powerful computer.

3. Mobile Streaming Options

An app such as Teradek’s Live:Air video switcher allows broadcasters to multi-camera live stream video from multiple iPhone and iPad sources.

These days, it’s possible to wirelessly switch a multi-camera live video broadcast using mobile devices. Considering that a full broadcast studio was the only option for performing this feat a few years ago, it’s pretty remarkable how fast the technology is evolving.

For a great mobile option, consider Teradek. We recently reviewed Teradek’s Live:Air Family of iOS apps. These allow you to mix multi-camera live streams from an iPhone (up to two cameras) or an iPad (up to four cameras).

Other similar options include RecoLive MultiCam and Switcher Studio.

4. Camera Capture Devices

Camera capture devices such as Black magic allow broadcasters to utilize multiple cameras to capture video and zoom in from different angles.

If you’re running a software switcher, you’ll need a camera capture device. This connects to your camera (usually via SDI or HDMI) and imports the video signal. Capture devices usually come in two formats: cards that slot into desktop computers or boxes that plug in via USB, Thunderbolt, or other connectors.

Two popular manufacturers of capture devices are Black Magic Design and Matrox.

5. Non-Camera Sources

A chroma key is a solution for shooting a video before a blank green (or blue) screen background and then replacing that screen with another background.

Other, non-camera sources can be added to live streams as well. These include:

  • Animated graphics
  • Chroma key (green screen) backgrounds
  • Titles and lower thirds (text)
  • Images
  • Pre-recorded video content

Any switching software or hardware platform will include a method for inserting this sort of content with minimal fuss. Usually, switching to a non-camera source is as simple as hitting a button or selecting content. Overlaying titles, graphics, or other material is straightforward as well.

Steps for a Successful Multi-camera Event

Here are our top 10 tips to successfully live stream and event with a multi-camera, multi-source equipment setup.

Let’s now consider streaming solutions for broadcasting live video stream in the flow of a multi-camera event. Generally, we recommend the following steps:

  1. Camera operators and techs should arrive early and begin set up well in advance.
  2. Chose camera angles and a location for the studio/switcher.
  3. Run and tape cables securely. No tripping!
  4. Set up and test encoders, computers, and switchers with the cameras.
  5. Conduct a full live-streaming test. We recommend testing at least twice and on multiple end-user devices.
  6. We recommend starting the main event live stream well before the event starts, showing an animated graphic (perhaps with a countdown).
  7. When the event begins, the switch operator switches to a camera view. You’re live!
  8. Throughout the show, switch between multiple cameras to provide an interesting and focused main view. The switcher controls this aspect.
  9. Ideally, each camera records its own feed to local storage (ISO); the main program feeds also records (locally, via OVP, or both).
  10. When the event ends, we recommend leaving the live stream up and running with another graphics showing. This graphic could include a call to action, such as “purchase the event recording at this URL.”

Picture-in-picture and multiple simultaneous views

Another type of multi-source live streaming is picture-in-picture. This is great for sports and many other scenarios. Similarly, streaming a multi-source collage is a viable approach. This one may have more limited uses, but can be fantastic for showing multiple simultaneous views of the same event.

Every live streaming software encoder – and most hardware encoders – make these effects possible.

When using OBS Studio or Wirecast, for example, you can individually scale, resize, position, and layer. This allows you to create a “picture-in-picture” effect, or merely display multiple cameras feeds onscreen at the same time.

    Is it possible to live stream from multiple locations? We are toying around with a project idea but one person is in NC, one in WI, one in CA, and I am in TN. Or is this too ambitious for rank amateurs?
