In addition to releasing the new RTX 40 SUPER graphics card at CES 2024, NVIDIA also announced its cooperation with Twitch and OBS to launch the Twitch Enhanced Broadcasting function. Using Multi-Encode technology, it can provide multiple sets of image resolution encoding during live broadcast, allowing Audiences can watch smoothly in different environments.
Although Twitch itself provides a variety of video resolutions to choose from, when it comes to live broadcasts, only Twitch partners can guarantee real-time multi-resolution services, and ordinary users are likely to completely follow the image quality settings of the live broadcast software. Streaming and saving the VOD when finished will not give you the option of additional resolution.
The main reason for this kind of differential treatment is not difficult to understand. After all, simultaneous conversion during the live broadcast will consume a lot of server resources. However, this is also painful for the general audience. Since there are no other resolution options, if you are in an outdoor network environment In a bad situation, the video content is prone to freezes or interruptions.
In this regard, NVIDIA has specially cooperated with live broadcast software and OBS to introduce the Multi-Encode function for “all RTX graphics cards”, allowing live broadcasters to simultaneously provide multiple resolution video formats to Twitch servers during live broadcasts. In this way, even if you are not a Twitch partner, you can instantly open multiple resolution options.
Currently, Twitch Enhanced Broadcasting is still in the Beta stage. Live broadcasters must use the beta version of OBS software to enable this feature. By default, the program will automatically determine the user’s hardware, network environment and other information, and automatically provide 3 image quality solutions. , the total required upload bandwidth falls between approximately 4 – 10 Mbps, of course, users can also adjust additional bandwidth according to their preferences.
Finally, new technology enhances AV1 video encoding streaming. Compared with the common H.264 encoding, not only the compression efficiency is increased by 40%, but also clearer images can be retained without taking up more bandwidth. quality.
At present, the Twitch Enhanced Broadcasting Beta function has been officially opened, and interested users can start to experience the new live streaming settings.
