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.

Blu-rays are compressed. "Zipping a zip file" doesn't apply here because zips are lossless. Video encoding is almost entirely lossy, and there's a lot of tradeoffs to be made between file size and quality. The whole point of the more efficient codecs is to minimize the quality tradeoff. There's also a bunch of parameters to tune the resulting bitrate which is the #1 factor in deciding the final filesize.

That being said, I'll agree that the least quality loss will come from using a Blu-ray remux since those are very high quality.

Blu-rays are compressed.

All streaming data is compressed at some point. I clearly meant not over-compressed. 4K video or UHD BD can both be taken from their original states and processed through HEVC to get crisp 1080p h265 10bit at a steep data discount. But it'll take a very long time to process. It's simply not worth it.

“Zipping a zip file” doesn’t apply here because zips are lossless.

It's a figurative expression and I feel that was pretty damn obvious...
