NVIDIA and Twitch Enhance Livestreaming with New HEVC Support

At TwitchCon, livestreamers and content creators can explore the latest technologies designed to enhance creative workflows and video quality, according to the NVIDIA Blog.

Twitch Enhanced Broadcasting With HEVC

One of the standout announcements is the beta release of Twitch Enhanced Broadcasting support for HEVC when using the NVIDIA encoder. This new feature aims to resolve the long-standing tradeoff between higher-resolution video quality and reliable streaming. Higher-quality video offers a better viewing experience but can cause buffering issues for viewers with lower bandwidth or older devices. Conversely, lower-bitrate video streams seamlessly but often lack quality.

Developed in collaboration between NVIDIA and Twitch, the Enhanced Broadcasting feature allows for multiple streams—each with different resolutions or bitrates—to be sent directly from NVIDIA GeForce RTX-equipped PCs or NVIDIA RTX workstations. This ensures that viewers receive the highest quality video their internet connection can handle. Notably, Twitch streamers using the NVIDIA encoder will benefit from a 25% improvement in efficiency and quality over the previous H.264 standard.

AI-Enhanced Microphones and Webcams

NVIDIA’s technologies also extend to enhancing hardware peripherals like microphones and webcams. The NVIDIA Broadcast app, along with eighth-generation NVIDIA NVENC and RTX-powered optimizations, transforms any home office or dorm room into a professional studio. The app includes AI-powered features such as Noise and Echo Removal for microphones, and Virtual Background, Auto Frame, Video Noise Removal, and Eye Contact for cameras.

Streamers can download the Broadcast app or access its effects across popular creative applications, including Corsair iCUE, Elgato Camera Hub, OBS, Streamlabs, VTube Studio, and Wave Link.

Spotlight the Highlights

GeForce RTX GPUs significantly speed up video editing processes on popular applications like Adobe Premiere Pro and CapCut Pro. AI-powered, RTX-accelerated features such as Enhance Speech, Auto Reframe, and Scene Edit Detection make video editing more efficient and effective. The GeForce RTX 4070 Ti GPU and above come equipped with dual encoders that can be used in parallel to halve export times on apps like CapCut.

Clearer, Sharper Viewing Experiences With RTX Video

NVIDIA RTX Video, exclusive to NVIDIA and GeForce RTX GPU owners, turns any online and native video into pristine 4K HDR content using Video Super Resolution and Video HDR technologies. Video Super Resolution de-artifacts and upscales streamed video, resulting in cleaner and sharper visuals. Video HDR converts standard dynamic range (SDR) video into HDR10 quality, offering a wider range of brights and darks and making visuals more vibrant and colorful.

RTX Video HDR requires an RTX GPU connected to an HDR10-compatible monitor or TV. More information is available on the RTX Video FAQ.

Attendees of TwitchCon, taking place in San Diego and online from September 20-22, will have the opportunity to experience these updates firsthand.
