[lug] Open Source Video Encoding Formats...Multiple Video Layers?

[Chip Atkinson]

kdenlive also allows compositing of clips. You can also specify masks to 
incorporate parts of one clip into another.  I installed and played with a 
number of video editors and re-settled on kdenlive

If I could add multiple video outputs for recording into a single recording, but then later disable/enable (such as in Gimp), then it would make life a lot easier. If there were already mainstream formats supporting video (and not just audio) as multiple tracks I think I would see what I could break to put it all in one package.

I was tinkering with the idea of creating a Vulkan capture program, but without an existing file format supporting video tracks/layers, I think I'll skip it.
