Livestream Studio gives you the ability to choose up to four auxiliary output mixes. This can be helpful for changing picture-in-picture and output sources (monitors, projectors, etc.).
Navigate to settings, and enter the Outputs menu. Under Number of AUX Mixes, select how many auxiliary outputs you want to use.
You can set any output to use an auxiliary source, which is helpful if you intend to change the sources shown to your onsite viewers.
When you set your auxiliary outputs, you should see an AUX Outputs tab appear in the lower right section. Each auxiliary output includes all camera inputs, graphics tracks, media bins, remote cameras, RTMP inputs, and NDI inputs.
To utilize this with your picture-in-picture graphics, go to a Graphics tab (e.g., GFX 1) and create a new layer.
Click the Paintbrush icon.
The GFX Designer will open. Click on the Video button to bring a video source into your graphics layer.
Click on the dropdown menu to change any settings, including your video source. Note that AUX sources are now among your options.
When you have finished setting your video source in the graphics layer, close out of the GFX Designer and make sure that layer is visible.
Navigate to the AUX Outputs tab of the AUX source you are using. Here you can select which of your inputs you want to see in the AUX output. You can choose among camera inputs, media sources, remote cameras, and NDI sources.
Push the graphics channel to Program to allow you and your viewers to see it.
To change the source in your graphics overlay, go back to the AUX Outputs tab and click on the desired source. That source will turn green, indicating that it is being previewed.
To switch sources, use either the Cut or Auto button to the left.
If you click on the transition type under Auto, you can choose both the type and speed of the transition used for each AUX source.
Click a transition control and the AUX Outputs tab will indicate that the new source is being pushed through that auxiliary source by highlighting that source in red.
You will also see the change in your graphics overlay in Preview and Program.
