Do all this within Vegas Pro? In my Lifetime? I never ever thought I'd see this moment (I gotta get out more . . . . . )

Another thing, having made Version-Centric BAK folders, and presently . . . . this IS behaving itself.

I'm using GPU acceleration; multiple tracks; 3 layers of Compo'ed Particle Illusion; Uploads to Dropbox; Renders . . . . . a mass of stuff going on.

Anyhoo, the newest sample for you https://dl.dropbox.com/u/20371960/Sony%20Vegas/Forum%20Media/FireTExt%20Particles%20in%201920x1080p%20MC%20MP4%20Text%201a.mp4
