Anecdotal evidence. But doing H.264 to HEVC encodes on my GTX 1080 result in significantly smaller files than Blu Ray rips I purchased the X-Files Blu Ray Box Set. Ripping it all to my hard disk resulted in roughly 1.7 terabytes of footage Encoding them with a likely higher than needed bitrate to preserve quality shrank them to a much more palatable 237GB (with subtitles) https://i.imgur.com/eJFuxaV.png https://i.imgur.com/eJFuxaV.png Bar removing the film grain (which I prefer, but not everyone does) I think the quality looks absolutely spectacular https://i.imgur.com/xlWJEol.jpg https://i.imgur.com/xlWJEol.jpg

The image you linked to exhibits horrible artifacts - but then again, you saved the screencap as a JPEG then uploaded it to a service that likely further butchers the image.

  It looks like VLC at saved it as a 1.5 meg PNG, then Imgur chewed it up and spat out a JPEG, irritating Here's a shot from a discussion a few weeks ago on HN I took of Star Trek: The Next Generation. It seems to have survived Imgur-ification much better https://i.imgur.com/VklppOK.png https://i.imgur.com/VklppOK.png

  Afaik Imgur doesn't process PNGs at all, while I'm not sure about JPGs (they might render previews, but I'd expect direct links to lead to the original file). Besides the weird new social stuff they're still by far the best image hoster I know.

The NVidia GTX compresion for HEVC is really bad, and only intended for use with live streaming. If you compare to similar file sizes or even half the size for x265 (CPU) encoding the quality is a lot better. As you note, the size is a bit larger than probably could be achieved... I also have encoded a bit using my GTX for hardware, but the quality:size difference was a bit much. Now when I do it, I just rip as much as my system can hold, then batch everything up and let it run for days/weeks. Currently using an i7-4790k (nearly 5yo), which doesn't have a the current intel hardware encoding options either. Considering upgrading to a Zen 2 Ryzen or Threadripper when they come out later this year.
