This is very much a "meta" question, rather than something specific ffmpeg, but it feels like there's so much discussion of video settings here, that it's a reasonable subject.
The background to my question is that I am using Video Enhance AI[1] to upscale and cleanup a number of old videos. I've set VEAI to write the results as a sequence on PNG images, and I now intend to use ffmpeg to create compressed video streams (H.264 or H.265) and mux the audio back in to a final MKV container. My challenge is to determine my compression settings in any reasonable sort of time, without driving myself insane. Most of the guidance I've been able to find seems to boil down to "try some stuff and look at the results," which really isn't practical when one considers the sheer number of different variables, the time required to compress even a short video sample, the time required to watch various different versions of the sample, and (most importantly) the inability of human vision and memory to make any reasonable comparison between subtly different video clips watched several minutes apart. So I'm curious how others go about this. Do you have a particular workflow that you use to determine good compression settings for a video? Are there any video quality metrics that you find to be useful in such a scenario (e.g. VMAF or others)? Something else? I can't be the only person to struggle with this, can I? Thanks!
