Having spent time reading the standards recently (and implementing some toy decoders) I&#x27;ve noticed a pattern in video codec designs, starting from the very first one:<p><pre><code> H.261 - simple, not much more than MJPEG with P-frames. MPEG-1 - basically &#x27;261 with B-frames, pretty simple MPEG-2&#x2F;H.262 - MPEG-1 with more complex interlacing stuff H.263 - no more interlacing, better low-bitrate performance MPEG-4 - absurd complexity that no one turned out to use most of anyway (3D scenes, face animation(!?), etc.) H.264 - back to regular video, with better I prediction H.265 - complex again? </code></pre> Of course they do get more complex over time, but it seems like a cycle that alternates between incremental-yet-significant changes and huge redesigns that don&#x27;t seem quite worth it.

Must say I&#x27;m massively surprised at how low adoption of 265&#x2F;hevc is in ahem the eyepatch wearing part of the internet.

I wonder if there is an article that compares X265 and <a href="https:&#x2F;&#x2F;github.com&#x2F;intel&#x2F;SVT-HEVC" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;intel&#x2F;SVT-HEVC</a> (in terms of speed, feature set, required hardware, software license, etc..) ?

Can&#x27;t wait for fast AV1 encoders, and especially hardware support.

From completely personal opinion and that of close friends:<p>x265 movies look way cleaner while having way smaller file sizes.<p>Also it&#x27;s the best tradeoff between quality&#x2F;filesize by factor of 2 or more. I&#x27;d personally notice artifacts in x264 movies unless they were over 7gb in size. With x265 i&#x27;ll grab a 3gb version of a movie in a heartbeat (well a few heartbeats on gigabit fiber :) and not worry about picture quality at all.<p>at 15gigs or more for a 1080p movie x264 is pretty much perfect, unless you really want to see the film-grain.

Great to see Dolby Vision in the features there - I&#x27;ve been very impressed with it vs HDR10.

Why not admit AV1 is all around better and work on it instead

Am I the only one who came to TFA looking for a screaming ThinkPad with a 7-row keyboard? <i>&lt;snaps fingers&gt;</i><p>(downvotes—rly? That really was my first thought when I saw the title ...)
