GeForce RTX 40 Series GPUs usher in a new era of high-quality streaming with AV1 encoding support on the eighth-generation NVENC.
Better Streams With NVENC, NVIDIA Broadcast Learn how to configure OBS Studio for streaming AV1 with GeForce RTX 40 Series GPUs in the OBS setup guide. Enhanced RTMP ingestion has been released as a beta feature on YouTube. The enhanced protocol also adds support for HEVC streaming, bringing new formats to users on the existing low-latency protocol they use for H.264 streaming. Support for AV1 on YouTube comes through the recent update to RTMP. Even in network-limited environments, streamers can now reap the benefits of high-quality video shared with their audience. The previous standard for livestreaming, H.264, usually maxed out with 1080p at 60 fps at the commonly used bitrates of 6-8 Mbps, and often produced blocky, grainy images.ĪV1’s increased efficiency enables streaming higher-quality images, allowing creators to stream at higher resolutions with smoother frame rates.
This work was necessitated by gamers and online content creators who pushed the boundaries of old formats that were defined roughly 20 years ago. AV1 - The New StandardĪs a founding member of the Alliance for Open Media, NVIDIA has worked closely with industry titans in developing the AV1 codec.
For example, AV1 enables streaming 4K at 60 frames per second with 10 Mbps upload bandwidth - down from 20 Mbps with H.264 - making 4K60 streaming available to a wider audience. At higher resolutions, AV1 encoding is even more efficient. This reduces the upload bandwidth needed to stream, a common limitation from streaming services and internet service providers.
This latest software update adds support for AV1 streaming to YouTube over Enhanced RTMP.Īll GeForce RTX 40 Series GPUs - including laptop GPUs and the recently launched GeForce RTX 4070 - support real-time AV1 hardware encoding, providing 40% more efficient encoding on average than H.264 and delivering higher quality than competing GPUs. AV1, the next-generation video codec, is expanding its reach with today’s release of OBS Studio 29.1.
