I realize it's not obvious how this might integrate in Vegas Pro, but I've often thought how awesome it would be to enable Vegas Pro to be used as a live compositing tool.
Imagine if we could ingest a live video sources (e.g. UVC Camera input or HDMI capture device), apply all Vegas compositing VFX and AFX plug-ins, and then send the preview out to our live stream.. SO POWERFUL! I suppose that's sorta like merging or interfacing Vegas Pro with Vegas Live. It'd allow us to utilize all the power of Vegas Audio FX chains, as well as adding really sophisticated video fx chains...
Thoughts?
