Unrelated question. What’s a video card that can transcode AV1? I want to add more AV1s to my jellyfin server but i’d need at least a nvidia RTX 4060 if i want AV1 transcoding >_<

The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:
Rules (interactive)
Rule 1- All posts must be legitimate questions. All post titles must include a question.
All posts must be legitimate questions, and all post titles must include a question. Questions that are joke or trolling questions, memes, song lyrics as title, etc. are not allowed here. See Rule 6 for all exceptions.
Rule 2- Your question subject cannot be illegal or NSFW material.
Your question subject cannot be illegal or NSFW material. You will be warned first, banned second.
Rule 3- Do not seek mental, medical and professional help here.
Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.
Rule 4- No self promotion or upvote-farming of any kind.
That's it.
Rule 5- No baiting or sealioning or promoting an agenda.
Questions which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.
Rule 6- Regarding META posts and joke questions.
Provided it is about the community itself, you may post non-question posts using the [META] tag on your post title.
On fridays, you are allowed to post meme and troll questions, on the condition that it's in text format only, and conforms with our other rules. These posts MUST include the [NSQ Friday] tag in their title.
If you post a serious question on friday and are looking only for legitimate answers, then please include the [Serious] tag on your post. Irrelevant replies will then be removed by moderators.
Rule 7- You can't intentionally annoy, mock, or harass other members.
If you intentionally annoy, mock, harass, or discriminate against any individual member, you will be removed.
Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.
Rule 8- All comments should try to stay relevant to their parent content.
Rule 9- Reposts from other platforms are not allowed.
Let everyone have their own content.
Rule 10- Majority of bots aren't allowed to participate here.

WDYM by "add more AV1s to my jellyfin"?
As in have AV1-encoded source files and have jellyfin transcode from AV1 to more compatible formats or to have jellyfin transcode existing videos (no matter what format) to AV1 in real-time?
For the former, you shouldn't need any special GPU whatsoever as a CPU can decode AV1 just fine but a GPU capable of AV1 decode could help. That's Ampere, Navi 2 and tiger lake or later.
The latter isn't very useful right now as a device capable of decoding AV1 must be quite modern and those are usually in a position to just decode the original without any need for any transcoding.
I meant The former
Intel Arc A380. It’s super cheap and supports encoding AV1 through Intel QuickSync. It’s what I have in my Jellyfin server.
Amd's 7000 series can encode AV1 too. Most people probably go for Arc cards
Any of the Intel arc cards can do it. If you are wanting a budget option the a380 is a low power option. However don't expect to use it for gaming. If you also want gaming then the a750/a770 are better choices but don't expect quite the same level of compatibility with games that you get from nvidia
There's an even lower power a310 now, I think it's even low enough power to be powered solely by the pcie slot
Yes, it's just more advanced compression as more and more techniques are discovered and fine-tuned.
To give a feeling of how they work, some of the simpler tricks they use are:
Find a polynomial function that closely matches a sound curve - storing 3183x^3 - 1/13847x^2 + 11x - 9 takes less space than one hundred consecutive frequency numbers.
Cut out sounds that humans don't hear. After a sharp clap, we don't hear certain frequencies for a few tens of milliseconds.
There are tons more, most too advanced to explain in a lemmy comment. :)
Isn't it also partly that as processing power increased, you could do more sophisticated compression/decompression in real time compared to previously, allowing these more complex compression algorithms to actually be viable?
I.e. they actually knew how to do it before, they just didn't have the power to implement it
Processing power in general has improved, but there's also specific sections of the cpu/gpu built dedicated to en/de-coding in those codecs. (in newer hardware).
Less reliance on software figuring out which stream of commands to send the cpu/gpu to get the desired results, and more just handing the cpu/gpu some file data then receiving the output.
It's a combination of that. Compression technology and technology in general are built upon the successes and ideas of the previous generation. What can happen is a bunch of methods are created and the popularity of them dictates their future. Eventually those compression algorithms are put into hardware allowing future devices an easier time using it.
So essentially experimental algorithms are adopted by the industry and power users and whatever ends up winning that popularity contest gets added to weak devices such as netbooks and TVs.
We're currently at the point where AV1 is starting to be deployed in hardware and streaming services have been switching to it for efficiency.
