Hi there, Moritz

If you can describe it mathematically, you may be able to use ffmpeg's

However, actually producing them from the input would be tricky.
With 4K footage there are quite a lot of pixels to track where they went.
I don't even know where to start. It would be nice if I could put a
specially crafted image through the toolchain, and then have the map at the
end to apply over and over.

Why thank you! It's my day job. :D
