The latest generation of video cards has brought some interesting technologies, one of which is hardware support for the AV1 codec. Unlike the old H.264 (AVC) standard, which is still widely used today, it is free and completely open. Due to H.265 (HEVC) and H.266 (VVC) pricing, AV1 has become the biggest hope for video creators and especially streamers who were severely limited by the old codec. And it will soon become a reality.
While Twitch still doesn’t support AV1 in any way, YouTube is very close to it. On the platform side, Google will soon implement the Enhanced RTMP streaming protocol, bringing support for VP9, HEVC, and just AV1. Also key is software support coming soon as OBS version 29.1 which is 92% complete. This will allow AV1 to be used in NVENC (RTX 40) and QuickSync (Intel Arc) versions for streaming, AMD graphics support coming later. It is worth adding that streams still will not work natively through AV1, the image will be sent to YouTube, where it will then be converted to AVC (at 1080p and lower resolutions) or VP9 (at resolutions above 1080p). When converting to AVC, there will be a significant loss of quality, so it will be better to stream at 1440p even at a lower bitrate.
Although this feature has not yet appeared, YouTuber EposVox has already been able to try it out, and you can watch it being tested in the video above. According to his findings, for a 1440p 60 FPS stream, speeds from 4 Mbps to 8 Mbps are sufficient, depending on the game. But these are really very small numbers, given the quality that can be extracted from them. For 4K and 60fps, EposVox recommends a bitrate of around 15Mbps.
Earlier we devoted a separate article to the AV1 codec itself.
