    I guess it’s theoretically possible, but probably impractical. I think your script would have to create an expression to use sampleImage() to sample every pixel on every frame. You might be able to streamline it somewhat by first sampling the entire frame and comparing, if they don’t match, move on, if they match, then cut the frame into two pieces and make sure they match, etc. Eventually you’d end up sampling every pixel to make sure the frames match exactly, but you’d eliminate frames that don’t match fairly quickly.
