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.
The unfolded icosahedron is obviously not one of the options yet.
Maybe some demand for it in the future, becoming increasingly popular
in the machine learning game.

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.

Yeah, not ideal.
I don't use it for images, I have my own solution for that with
supersampling antialising.
But for movie conversion, what

Yeah, not ideal.
I don't use it for images, I have my own solution for that with
supersampling antialising.
But for movie conversion, what is the alternative? I on occasion
- Extract
Figured as much, installed 4.3.1 ... works a treat, thanks!
I sent you an image but was too large and got blocked.

If you switch to last ffmpeg version, there

Apologies in advance if I simply didn't search the documentation
How do I change the colour actually used as the chromakey colour?
I am creating remap filters to do various image mappings and would
like undefined pixels to be black rather than green.
Apologies in advance if I simply didn't search the documentation
sufficiently well.
