I'm sort of interested in stealing Levi's idea and making a community montage of my own (with his blessing I hope), but the issue right now (and the reason I don't use demos) is because they don't show health/jet. In playback both bars are totally empty. Since my montages center around dueling...
I know. It's good for slow-mo/frame blending. I've got a program that lets me halve the speed by converting from 60 fps to 30 fps, so when I put it in my (ancient) editing program (that also can't handle 60 fps) I've either got perfectly smooth slow-mo or real-time speed with frame blending...
Since you're using demos, if you want I can process them for you. I can record the bits you want at 1080p and 60 fps, export as mp4, and send them to you via mediafire. Does that work for you? I love your idea, dude.
