The scene values quality. It's why their file sizes seem large to some. x264 at CRF 18-21 still can't be matched by x265 at any bitrate. I'm a videophile and have been using Avisynth (Vapoursynth mostly these days) since the DivX vs Xvid wars and every year I give x265 another chance only to be disappointed. There's also the hardware compatibility issue but regardless the quality would still have to be there. Take a look at the most popular outstanding bugs and you'll notice many of them are regarding quality [1] The doom9 forums is also a good source. Many have posted comparisons proving the point.

Really, it's blurry even if you throw a bunch of bitrate at it? Seems odd. The one area with significant uptake that I've seen so far is anime, which if regular stuff gets blurry does make sense. The quality is actually really great there, and it can produce files that are extremely small at good quality (eg 25 minutes at 1080p with multi-language AAC tracks is often around 250-300 MB, with bluray quality). (oh, also there is a poster who used to do a lot of scifi releases in x265, it looks OK although not bluray quality, and you can get a 45 minute episode in 1080p quality in about 700mb) Personally I've tried encoding Shadowplay recordings to x265 a couple times (via ffmpeg, both through Handbrake and directly invoking ffmpeg on my server) and I get solid green video. I think it's the variable frame rate, it works OK if I pull it down to a constant framerate first, but that can produce juddering if I get framedrops when I'm playing.

  Anime are comparatively easier to encoder due absent of grain. And large blocks of colour do very well with improve h265 efficiency. Not to mention a lot of the psychological model imported from x264 had decades of Anime tuning in it.

> The scene values quality. It's why their file sizes seem large to some. So many groups are still releasing shows & movies in XviD so I don't think that's necessarily true, you think by now everyone would be on x264.

  I was referring to The Scene [1]. They stopped releasing in Xvid around ~2012. What you're talking about are known as "peer groups". These groups/individuals do as they wish (to put it kindly). [1] https://en.wikipedia.org/wiki/Warez_scene https://en.wikipedia.org/wiki/Warez_scene

I would have thought it was more preferring faster pretimes, as X264 encoding is much faster than X265? At least in the case of TV shows, maybe not so much movies where there might be a more exclusive source.

>There's also the hardware compatibility issue Seems to be getting better (slowly). I just bought an asus tinkerboard for 50 bucks that supports 265.
