Quote:For CRF lossless encoding, x264 Frames, GOP parameters settings, do they matter?a. there is no difference between "--qp 0" and "--crf 0", so there is no crf lossless.
b. other parameters still matter, as they can increase the compression ration (more references, analysis, etc. can result in smaller output size)
Quote:AVC Profile" to either "None" or "High4:4:4", should I check, compare to different ones?Probably doesn't matter. Only difference is that Hybrid will explicitly add '--profile high444' which will enforce High4:4:4 signaling, but x264 should also that signaling.
Output will still be lossless so quality wise there is no difference.
