But again: if you are doing slow filtering and slow x265 encoding the difference between uncompressed or lossless x264 --preset ultrafast intermediate is probably not worth worrying about. If you want to know exactly you have to benchmark it.

I thought of doing this:
Code:
ffmpeg -i inputfile.vpy -c:v rawvideo outputfile.yuv
so you suggested vspipe, so maybe this:
Code:
vspipe script.vpy output.raw
or add --y4m
I will try next time to see how much time will it take. Lossless x264 ultrafast 1080p is about 8 hours.
