What I wanted to do with this assignment was to use delay to isolate movement within a video, and show only the subject on an empty background. I got something pretty cool – but only by accident.

I started with the first video, which is from Generate by Rasmus Ott (on YouTube). By delaying the initial matrix and then subtracting the original matrix from the delay, I got the second iteration. Pretty cool, and I sort of isolated the subject, but it wasn’t what I wanted. Then, when I unlinked the delayed matrix from the jit.expr object, it froze it and left only the (anti-?)silhouette of the original behind. I really like the aesthetic of a moving subject revealing the background, but I couldn’t figure out how to replicate this in a non-janky way. Anyway, here’s the gist:
