For those of you that torrent video files this question is geared toward you. I’m looking for a sweet spot between quality, size & speed for HEVC encoding. I’m using FastFlix and seem to be getting really wide and varying speeds.

I’m not really literate on all this video lingo but I can, at least, get it going. Most files take anywhere from 5-17 mins for a 30-40 mins clip. I have a AMD Radeon RX 470 graphics card but when I try and use the VCEEnc it won’t let me use CRF which I’ve heard it the best way.

Anyway, if you’re willing to share knowledge or what settings you use when you convert video to HEVC that might help me speed up my processing, I would be eternally grateful.

    1. This number is taken from the Wikipedia page, and represents a lab setting from totally uncompressed to full HEVC encoding. It’s not representative of data savings that you get from one video codec vs another, which is likely less than 4-6% between something like VP9 and HEVC… The 25-50% of completely fucking laughable in a realistic setting and you look like and idiot for bringing it up.
    2. It’s absolutely an overestimation by every conceivable metric available.
    3. You can encode to whatever you want, but if you take a VP9 encoded video and re-encode it, you may only save 1% and it will take several hours to encode. There are even situations where you will save nothing, or the resultant video file is actually larger even with HEVC.

    It’s zipping a zip file. Endlessly re-compressing things doesn’t yield positive results in the way you describe.

      no it isn’t, zipping is lossless. encoding is lossy.
