Sorry for an irregular post, just thought it'd be fun to pass this idea onto someone else.

multiple layers on top of each other, blending mode overlay (or something that works) then speed ramp from slow (below regular 1 speed) to maybe slightly above regular speed (1.2x speed). each layer will start at a slower speed than the one before, so it'd look like:

Top layer: speed ramp from -2 to 1.2x speed (& overlay)

middle layer: speed ramp from -1.5 to 1.2x speed (& overlay)

third layer: speed ramp from -1 to 1.2x speed

main layer: 1x speed.

I'm curious to know what this would look like, as compared to just delaying the video and overlaying it, like 1st layer is at 1st frame, 2nd layer is overlay and starts at 2nd frame, etc. It's cool if I never see an example too. Just passing creativity along.
