    x264 only got good when Dark Shikari started working on it, adding all sorts of psy enhancements, like variance based adaptive quantization and psychovisual rate-distortion decisions. When VAQ was being developed, there was a huge thread at the doom9.org forums where people tested out various experimental settings. Everyone used their eyes in those tests and posted example screenshots, no one posted metrics. *That* is how you make a good encoder, not by plotting PSNR and SSIM graphs.
    That just means the metrics suck, not that you shouldn't ever use them.

    Testing "by eye" is always going to be a matter of guesswork. You can use it, of course, but what really needs to happen is someone needs to create a metric that properly measures things that match up to quality the eye sees.
