And decent resolution: DVD is forever stuck at SD (480p MPEG). While Blu-ray can be UHD (4K HEVC).

[–] Octagon9561@lemmy.ml 6 points 19 hours ago (1 children)

It's not even 480p, it's 480i with a resolution of 720x480 regardless of whether the content is 4:3 or 16:9, the pixels get stretched one way or the other. That's for NTSC discs, PAL discs have a higher 576i (720x576) resolution but the movie is sped up 4% cause it forces 25fps when it should be 24.

This is a good point. Even worse! Weird anamorphic? pixel aspect ratios (or maybe pan-and-scan crops? or hopefully that's just VHS). With a bonus of interlacing! "The horror!" I haven't ripped a DVD in ages due to video quality issues.

[–] Octagon9561@lemmy.ml 2 points 12 hours ago

Oh all those full screen DVDs are in fact pan and scan just like VHS.

I've always kinda thought about implementing a software and standard for 1080p av1 on DVD. Would be neat as a project, obviously no commercial use would exist.

Either way you can get some really impressive encodes out of av1, really neat tech.

[–] freeman@sh.itjust.works 2 points 19 hours ago (1 children)

Unless you get new DVD players to support AV1, just put the AV1 files on a data DVD..

No that's the idea, it would be to make a piece of software which if thrown on a sbc with a DVD drive becomes a player.

Which really isn't too far off of DVD and most bluray players.

Though I wouldn't be shocked if the super cheap DVD players have some sorta all-in-one integrated asic for most of the job.

Would mostly be used by hobbiest making their own burned discs and small artists releasing stuff.

I mean if you control the software on the "player" you don't really need a dedicated dvd format. Think about mp3 CDs, it never became a real format with specs and everything yet most CD players after a certain date supported them.

[–] magic_smoke@lemmy.blahaj.zone 1 points 4 hours ago

Yeah but if you make it an open format other hobbyists could make their own hardware/software about it.

Mostly a fantasy medium, but if people start using it they start using it.

That sounds interesting! I've been using AV1 more and more (thanks to SVT-AV1-PSY/-HDR and devs pushing improvements to main). Also enjoying FHD animated AVIF (vs ancient GIF, although gif.ski helps). AV1 video is not as soft as it once was (esp athigh bitrates with synthetic film grain), and combined with OPUS audio, it's all wonderful.

If you ever wanna play 4K BDs on PC, you'll need a 4K-compatible drive that's been hacked with LibreDrive though, otherwise you're stuck using a dedicated set-top player for those.

1080p discs can at least be handled by libaacs and libbdplus /w the necessary files, and don't necessarily need a hacked drive to play back.
