> Nice idea, what upscaling methods you use? Do you use swscale by any chance?

Not sure I understand. I don't upscale the movie/image, rather my code
that creates the remap filters just creates the maps 2,3,4 times
bigger than I eventually plan to use.

> And what filters for upscaling and later downscaling (bilinear/lanczos/spline/...) ?

Generally just bilinear.
