All codecs and encoding tools have a configuration option that controls the quality/encoding time tradeoff. With x264 (and x265) the preset controls that tradeoff. When choosing a preset you should consider 3 criteria: Overall quality – the overall quality produced by that preset Low frame quality – the quality of the lowest frame produced by…
I just saw Vimeo’s “isn’t it wonderful that we’re publishing video with AV1” announcement and felt the need to call BS.
