NVIDIA and Twitch Boost Livestreams with HEVC Support Upgrade

During TwitchCon, streamers and content creators can delve into the latest innovations aimed at enhancing creative processes and video quality, as stated in the NVIDIA Blog.

Twitch Enhanced Broadcasting With HEVC

A notable announcement is the beta launch of Twitch Enhanced Broadcasting with HEVC support using the NVIDIA encoder. This new capability seeks to address the longstanding compromise between high-resolution video quality and dependable streaming. While superior video quality enhances viewer experience, it may lead to buffering for users with lower bandwidth or older devices. On the other hand, lower-bitrate streams offer seamless viewing but typically sacrifice quality.

The Enhanced Broadcasting feature, developed through collaboration between NVIDIA and Twitch, allows for multiple simultaneous streams—each configured with different resolutions or bitrates—from NVIDIA GeForce RTX-enabled PCs or NVIDIA RTX workstations. This guarantees that viewers receive the best quality video their internet connection can support. Importantly, Twitch streamers using the NVIDIA encoder will see a 25% boost in efficiency and quality compared to the former H.264 standard.

AI-Enhanced Microphones and Webcams

NVIDIA’s advancements also extend to improving hardware peripherals such as microphones and webcams. The NVIDIA Broadcast application, alongside the eighth-generation NVIDIA NVENC and RTX-based optimizations, converts any home workspace or dormitory into a professional studio setting. This app includes AI-driven functions like Noise and Echo Removal for mics, and Virtual Background, Auto Frame, Video Noise Removal, and Eye Contact features for cameras.

Streamers can download the Broadcast application or use its effects within popular creative platforms, including Corsair iCUE, Elgato Camera Hub, OBS, Streamlabs, VTube Studio, and Wave Link.

Spotlight the Highlights

GeForce RTX GPUs substantially accelerate video editing tasks on major software like Adobe Premiere Pro and CapCut Pro. AI-boosted, RTX-enhanced features such as Enhance Speech, Auto Reframe, and Scene Edit Detection streamline the editing process, making it more efficient and effective. The GeForce RTX 4070 Ti GPU and newer models are equipped with dual encoders that can operate in parallel, halving export times in applications like CapCut.

Clearer, Sharper Viewing Experiences With RTX Video

NVIDIA RTX Video, available exclusively to NVIDIA and GeForce RTX GPU users, elevates any online or native video to stunning 4K HDR quality by employing Video Super Resolution and Video HDR technologies. Video Super Resolution eliminates artifacts and upscales streaming video, enhancing visual clarity and sharpness. Meanwhile, Video HDR upgrades standard dynamic range (SDR) content to HDR10 quality, expanding the range of highlights and shadows, resulting in more vibrant and colorful visuals.

RTX Video HDR requires an RTX GPU connected to an HDR10-compatible display. Further details can be found in the RTX Video FAQ.

Participants of TwitchCon, which will be hosted in San Diego and online from September 20-22, will have the chance to experience these upgrades first-hand.
