- dekhn 2y agoI spent some time with this on my data set, and in my hands I wasn't able to produce results that were convincingly better than libx264, but with slower encodes and larger output files. It's really hard to beat libx264.

Otherwise, it's not a valid comparison... "-crf 13" is nowhere near lossless (though it might appear so visually). FFV1 is much better than H264 at lossless compression in my experience. Here's a random sample of a ten second 4K input I had handy (5.5G uncompressed): h264-ultrafast 1.951s 850M h264-veryslow 46.528s 715M ffv1 8.883s 637M But yeah, if you don't actually require truly lossless data, it's a huge waste.
