Marcus Adams<p>So I'm doing some pixel peeping to look for differences in <a href="https://mastodon.social/tags/x264" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>x264</span></a> and <a href="https://mastodon.social/tags/AV1" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>AV1</span></a> encoding quality and while they've visually been pretty close, I've found one example where AV1 really trounces x264 at smaller size; Hacksaw Ridge. I originally ripped this Bluray with an RF of 20 to x264. Today's rip was to AV1 with RF 22. The smoke really shows how much better AV1 can be. x264 almost looks dithered, or like it's using a smaller color palette. Now extrapolate this out over the whole movie.</p>
Marcus Adams<p>x265 is considerably more efficient than x264. I just re-encoded the entirety of my copy of Farscape, from the same Bluray source discs. Here's a comparison of the final file size for each copy. Settings were as follows:</p><p>Both copies were encoded with an RF of 20, 1080p, framerate same as source. The <a href="https://mastodon.social/tags/x264" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>x264</span></a> copy only had a 160 kbps AAC stereo audio track. The <a href="https://mastodon.social/tags/x265" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>x265</span></a> copy included that, but also included an un-touched DTS-HD-MA surround sound track, as well as commentary audio tracks.</p><p><a href="https://mastodon.social/tags/Media" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Media</span></a></p>
Lukas Orsvärn<p>Actually, <a href="https://peoplemaking.games/tags/HEVC" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>HEVC</span></a> doesn’t work either, using <a href="https://peoplemaking.games/tags/x264" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>x264</span></a> instead. I don’t really understand why they don’t work since from what I’ve read they should have wide support. 🤔</p><p>Been learning more <a href="https://peoplemaking.games/tags/NixOS" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>NixOS</span></a> including <a href="https://peoplemaking.games/tags/HomeManager" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>HomeManager</span></a> so I can set it up as automated as possible. I’m considering learning setting NixOS up to pull the transcode script straight from a <a href="https://peoplemaking.games/tags/Git" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Git</span></a> repo, that would be cool!</p><p>That script now works on the <a href="https://peoplemaking.games/tags/RaspberryPi" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>RaspberryPi</span></a> 4. My current challenge is setting up <a href="https://peoplemaking.games/tags/Nix" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Nix</span></a> to run it when the machine turns on with <a href="https://peoplemaking.games/tags/SystemD" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>SystemD</span></a>.</p><p>I can’t really get SystemD to do anything at all, which is frustrating. Not sure what I’m doing wrong. 😑 Once that works though I think the system is operational!</p>
Colin<p>About 6 months ago I got a bee in my bonnet about the quality of current codecs. I ended up doing more than 1000 encodes, comparing various codecs, presets and quality settings. A little over a month ago I wrote something up about it. <br><a href="https://colinmckellar.com/2024/01/11/video-encoder-comparison/" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">colinmckellar.com/2024/01/11/v</span><span class="invisible">ideo-encoder-comparison/</span></a><br><a href="https://mckellar.social/tags/AV1" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>AV1</span></a> <a href="https://mckellar.social/tags/ffmpeg" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>ffmpeg</span></a> <a href="https://mckellar.social/tags/x264" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>x264</span></a> <a href="https://mckellar.social/tags/x265" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>x265</span></a></p>
DaGeek247<p>Comparing compression in AV1, x264, and x265</p><p>I recently got it into my head to compare the various popular video codecs in an effort to better understand how av1 works and looks compared to x264 and x265. I also had ideas of using a intel video card to compress a home video security setup, and what levels of compression I would need to get good results.... <a href="https://mastodon.gamedev.place/tags/codec" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>codec</span></a> <a href="https://mastodon.gamedev.place/tags/comparison" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>comparison</span></a> <a href="https://mastodon.gamedev.place/tags/quality" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>quality</span></a> <a href="https://mastodon.gamedev.place/tags/encode" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>encode</span></a> <a href="https://mastodon.gamedev.place/tags/av1" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>av1</span></a> <a href="https://mastodon.gamedev.place/tags/x264" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>x264</span></a> <a href="https://mastodon.gamedev.place/tags/x265" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>x265</span></a></p><p><a href="https://kbin.social/m/selfhosted@lemmy.world/t/733346" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">kbin.social/m/selfhosted@lemmy</span><span class="invisible">.world/t/733346</span></a></p>
