Breaking frames, video and looping

not really sure how to approach this … so this may be in the wrong section … apologies if it is.

what we’re setting out to achieve is something similar to this …

any ideas how this achieved? Is it literally breaking the video into frames or is it instancing the video a certain number of times and offsetting the next/previous frame?

if it’s the latter … what’s the most efficient way to handle that number of duplicates? I figure doing it that way would be too processor intensive … but I’m not a developer so shrug

any assistance welcome and appreciated.
