Music video final project for my Computer vision class. I made the lightpainting/motion tracking effect in Jitter and set it up live outside. People were interacting with it in real time (there was a projector and screen they were looking at) but at a low resolution. I filmed them simultaneously in HD and rendered later once I had edited things to the music.
I'm happy to share my code with anyone who wants it! It's a little outdated, but should work fine in max 5/jitter.
