OBS Studio supports AV1 encoding on RTX 4000 cards – Computer – News

Open Broadcaster Studio, or OBS, has added support for Nvenc AV1 encoding for Nvidia RTX 4000 cards. For now it only works for image recording and not yet for streaming, because services like YouTube and Twitch do not yet support the codec. .

Support is provided with version 28.1 of the software. Its tuesday officially released after a beta first came out. The release notes show how the Nvenc AV1 hardware encoder is supported on Windows. There are still limits; for example, there is no scaling in enhanced output mode and the tool only works in NV12 and P010 color formats. The codec only works on Nvidia’s GeForce RTX 4000 video cards. The RTX 4080 and 4090 both have dual AV1 encoders integrated.

Previous generations of Nvidia GPUs only supported AV1 decoding, but no encoding. AV1 encoder is about 40% more efficient than RTX 3000 series H.264 encoder and 30% more efficient than H.265 encoder. Users can stream it at 1440p, among other things, but in practice the usability will still be disappointing. Major streaming platforms like YouTube and Twitch don’t yet support the codec.
