H.264 Is Magic (2016)

You don't need to find the best possible encoding. SVT-AV1 can encode as fast as x264, keeping the same visual quality to human eyes while reducing bit rate by 50%.

If you want to retain visual quality, you always have an option to use higher bit rate.

If we assume that to be true (VMAF and SSIM aren’t the whole picture), just keep in mind that’s only true at particular speeds, bitrates, and types of content.

What I should say is, please show me an AV1 encoder that can beat x264 in quality at a source-transparent encode of a 4K or 1080p Blu-ray film, if given ~3GB per hour of content and the encode had to run in at least 3x the runtime. I’d start using it! It may be there as of recently, it’s been a year or two since I looked.

This is a usecase where AV1 encoders and even x265 have had trouble.
