[HELP] video processing

[Selur]

It's a quality based method for 1pass encoding, similar to a fluctuating variable quantizer encode, where the quantizer is chosen to match an average loss.
Most modern H.264, H.265, AV-1 encoder offer this rate control method.
Since you didn't post anything about what format you are using, I assumed it must be a modern one.
Maybe https://www.coconut.co/articles/crf-vs-b...eo-quality gives a low level understanding of what crf is.
