Ability to crop the reference video

[metabubble]

Hi

I would love to be able to pass a ffmpeg filter parameter to -r (and possibly to -d) files, so if I cropped my encode, I can crop the reference video to match the degraded file image size.

Thanks

Hi @metabubble

That sounds a good feature. May I ask you for a sample and more details of the use case so I can understand better what should be the expected usage.

python3 easyVmaf.py -r rfile.mkv -rfilters "crop=3840:1608" -d dfile.mkv

this would ideally pass the whole filter call to ffmpeg, so if there was any other transformations, like mirroring or rotating, it would also be possible to pass that along.
