Are you ready for a game-changing update to Twitch? At CES 2024, Nvidia and Twitch called “Twitch Enhanced Broadcasting.” This exciting new feature has the potential to revolutionize video quality on Twitch by making streaming easier, improving low-latency and buffer-free viewing, and enhancing the encoding experience. Plus, AV1 is coming to Twitch, too — though the timeline might be a bit further out than you’d hope for.
presents a new way for streaming from OBS Studio to Twitch, and it’s entering beta this week. The key features of Enhanced Broadcasting will allow the streamer to enhance Twitch’s stream transcoding on their own hardware and send multiple different quality versions of their stream to Twitch at the same time. Better yet, the sign-up for beta is accessible from streamers’ .
Two awesome changes are coming with this beta:
- Multitrack streaming to Twitch
- Automatic configuration of stream settings

Multiple video tracks
The first major change comes with a new revision to the Enhanced RTMP streaming protocol (which was introduced in early 2023 to accommodate AV1 and HEVC live streaming) that allows for multiple video tracks to be packaged in the same stream. While FFMPEG and other video encoding tools have been able to leverage multiple video tracks in certain file containers before, this is the first time traditional RTMP streaming has been capable of such complexity. Previously, OBS users have been able to for Twitch’s “VOD Track” feature: This update works similarly, but for video instead of audio.
Multitrack video opens up the possibility to send multiple different video tracks to Twitch in one RTMP stream, supplementing Twitch’s transcoding pipeline. During the initial beta phase, Twitch aims to target at a time, with the potential to reach a total of five concurrent streams (the driver-enforced encoding session limit for consumer GeForce GPUs) to cover a wider gamut of formats, and include higher resolution formats such as 1440p and 4K in the future.
Automatic settings configuration
Enabling Enhanced Broadcast in this new OBS beta will also take away the stress and complication of optimizing streaming and encoder settings for Twitch. This new service will ping Twitch’s servers, analyze the streamer’s system specs, available resources, internet latency and bandwidth, then generate the best settings for their stream (including adjusting how many transcodes are generated by the streamer’s hardware). This both optimizes the encoding ladder for optimal results from end to end,
