@thor That was precisely my point, it's not about having better screen, of course I do, I'm not limited by hardware, it's about having incentive to watch it in higher resolution or with better sound quality. You don't send uncompressed photos to your friends over IM, you use JPEG — if they want the higher quality higher resolution version, they'll ask you for it. Same with social media — it's for previews, you can provide a link to 4k version of course, 4k previews are a waste 🤷
@m0xee arguably, that's a Mastodon design decision. it *does* re-encode stuff when it deems it necessary, using FFmpeg, so it could do as YouTube does if it wanted to. as it is right now, it doesn't do anything if the clip is under 40 MB and in the correct format.
@LaoBan Sensible thing to do, considering that AV1 is relatively new and not supported in all browsers, most notably Safari, and on all devices.
I'm also reluctant to use it as it was created by Google-controlled Alliance for Open Media, I do my best to avoid WebP, WebM, VP9 and other Google shit.
Implementation is also flaky — I've tried ffmpeg to encode short video to AV1, it took 5 mins utilizing 100% CPU with a few kilobyte compression gains over H264 🤷
@thor
@m0xee @thor I'm pretty sure Apple is the only company without official AV1 support at this point, but then again unless you use Safari you won't have a problem.
Not everything Google does is evil. Everyone has an interest in having a free open source video codec for the web. The adoption of h.264 was an aberration.
Funny, I'm compressing videos right now and so far I can get about 20 to 30% compression gains over h.264 without any perceptual loss with the latest build of svt-av1. I do agree the compression times can be brutal, but that's because I don't have a hardware encoder yet.
@thor As for YouTube — having 4k is amazing, but YT re-encodes it to lower resolutions automatically. If I want a general idea what channel is about, I'd probably pick a lower resolution stream, again, not because I'm on limited data plan — I have a 100Mbps connection, but I'm not utilizing that 100% just because I can, it's pointless.
Like I said, there are always exceptions, some content might not make sense in lower resolution.
