Often in previs setups, you have several "variations" of image/movie strips for review, where the topmost one completely covers the others under it. VSE rendering already had an optimization where if there's a fully opaque strip that covers the whole screen, then the lower strips are skipped from processing/rendering. However, it was not handling the case of non-fullscreen strips (e.g. you'd have a Color strip near top & bottom for letterboxing, and an opaque strip "in the middle"). This adds a simple "occluder tracking", and skips strips that are completely covered by any single opaque strip that is above it (like outlined in #117790 task). Playback of Gold previs between 1:42 and 1:55, on Windows/Ryzen5950X: - Average frame time 28.5ms -> 23.8ms - Median frame time 24.1ms -> 21.5ms - Two slowest frames: 263->189ms, 194->178ms Rendering the Gold previs movie: 325s -> 304s (93% of previous time) Pull Request: https://projects.blender.org/blender/blender/pulls/118396
