All video codecs are lossy, meaning you will lose some quality. AV1 and H.265 are modern video codecs with the best quality to bitrate ratios, meaning you can get better quality for the same bitrate, or the same quality with a lower bitrate. The downside the these codecs is that they are very complex and computational expensive to do in software. You'll want to make sure your GPU supports hardware encoding for the codecs you intend to record with. The reason most people will recommend AV1 over H.265 is that AV1 is royalty free. With H.265, companies have to pay a royalty to use H.265. Because of this, most companies (Netflix, YouTube, Facebook, Twitch, etc.) want to use AV1 going forward, meaning in the near future, it will probably be the dominant codec.
well I checked. My GPU does support AV1, but only decode, and OBS doesn't support h265. So is my only (good) option is to use a SVT-AV1? How slow it that really?
are you sure about that? I'm pretty sure it should. maybe you'll find it as _x_265, as that's the name of the encoder it uses
I can't find it and a quick google told me that neither do others
OBS allows you to use everything FFmpeg supports with the "Custom Output (FFmpeg)" recording type.
I was and am searching there I just can't find it in the dropdown. I might be blind, but I checked multiple times.
Settings -> Output:
I've gotten that far, but no farther
turns out OBS does not have a software encoder for it, only encoding with a hardware encoder is supported. it is mentioned in the 2nd table of the video formats heading herev https://obsproject.com/kb/audio-video-formats-guide
