vainfoshould give you a good ideahttps://www.intel.com/content/www/us/en/support/articles/000098345/graphics.html
Looks like you can add VP9, and need to remove VC1
From what I could gather online, these seem to be the correct settings:

I’m not sure about VC-1, since there is conflicting official documentation:
My A770 doesn’t list VC-1 in
vainfo, so I doubt it’s supported.If you have any vc1 content why not try it and see. And if you don’t have any vc1 content, why worry?
I run everything but vp8 on. Can’t guarantee you won’t have issues depending on drivers and specific media files but this is what I use with the same GPU. Also I’m familiar with some other intel weirdness on jellyfin + Linux if you use Linux and run into additional problems.

Care to elaborate? Anything I need to keep in mind?
If you’re on debian 12 there’s a particular part of the drivers that you need to download from the Linux kernel website or transcoding won’t work at all. I don’t remember much else off the top of my head but I use an a380 in my server and a b580 in my desktop so I have some experience with intel stuff. If you get additional errors they may wake up some dusty neurons for me.
