As seen previously in the Live Event tutorial, there are 2 types of sources in the Live Mixer.
Live sources can point to live feeds either on the Deltacast input cards (SDI or HDMI) or streamed via NDI
Render Surface sources can map portions of our rendering workspace to make available as sources in the Mixer.


Additional render surface

Create another Render Surface and rename it Mixer Source. Keep the default size (1920×1080) and set its Y position to 1500.

Create another Timeline named Mixer Source and drag & drop the Nebula Loop media on it.

Set the media’s Y position to 1500 to place it on the previously created render surface. Set the media to Loop and Freerun.

In the Mixer panel, open the Sources tab and create a new source.

Select a Render Surface type source and point to the Mixer Source render surface.
