Popular video streaming software suite OBS Studio, in its latest version 28.1 release, adds hardware-accelerated AV1 encoding support for NVIDIA GeForce RTX 40-series "Ada" GPUs. This takes advantage of the updated NVENC hardware media encoders "Ada" comes with, which has fixed-function hardware to encode AV1 video, a royalty-free format that offers comparable quality and bitrates to HEVC. There are a handful limitations, besides the fact that this only works with the RTX 40-series. To begin with, only the NV12 (OBS default) and P010 color formats are supported. The "rescale" feature in advanced output modes, isn't supported for now. Grab OBS Studio from the link below.

No. It has already been proven superior to HEVC with comparable quality at lower bitrates to HEVC. You just need to get out of your cave.

Link?

AV1 seems to offer the same quality at up to 30% higher compression rate. It is free and supported by all the giants and it is possible to replace HEVC with the migration to 4K and 8K.

I used to stream with OBS, but that was a long time ago. Twitch owns(?) an OBS fork called StreamLabs so might have changed to that to be required.

No its just that Twitch does not support AV1 yet, you can use it in OBS just fine for recording purposes, and maybe for streaming to youtube, but you cant stream using AV1 yet to twitch.

Ok makes sense. So that makes me wonder if that is forcing streamers to use their software.

Streamlabs is owned by Logitech. It is not affiliated with Twitch.

I hope the AV1 support trickles down to the rest of the 8th gen cards...be it RTX4050 and so on.

we need av1 asap, streaming content are uploaded as videos now and its 1080p blurry mess and people just accept it....
streaming is the worst quality content on the planet and this could help out the problem.
