I’ve always thought that setting -crf [x] determines the output quality, while (in the same line) -preset [x] affected the output file size. (Where faster speeds result in bigger output files at the same quality.
But now this: https://trac.ffmpeg.org/wiki/Encode/H.265 <https://trac.ffmpeg.org/wiki/Encode/H.265> Under the Constant Rate Factor (CRF): -Put differently, if you choose ultrafast, the encoding process is going to run fast, and the file size will be smaller when compared to medium. WTF? I would think the output file size will be bigger? (I take it this is just a stupid mistake…) Then, the line continues: -The visual quality will not be as good. Now it gets confusing. This sorta kinda suggests that -crf and -preset are not to be used together? What am I missing here?
