Ahead of TwitchCon 2019, NVIDIA has announced the RTX Broadcast Engine – a collection of new SDKs that offer AI-powered greenscreen, augmented reality and style filters. Nvidia is working with all the top streaming app developers to integrate these into their software and plug-ins.

Powered by dedicated AI processors called Tensor Cores on RTX GPUs, the new SDKs enable virtual greenscreens, style filters and augmented reality effects — the kind of techniques used by major broadcast networks — all using AI and without the need for special equipment.

The new SDKs include:

  • RTX Greenscreen, to deliver real-time background removal of a webcam feed, so only your face and body show up on the livestream. The RTX Greenscreen AI model understands which part of an image is human and which is background, so gamers get the benefits of a greenscreen without needing to buy one.
  • RTX AR, which can detect faces, track facial features such as eyes and mouth, and even model the surface of a face, enabling real-time augmented reality effects using a standard web camera. Developers can use it to create fun, engaging AR effects, such as overlaying 3D content on a face or allowing a person to control 3D characters with their face.
  • RTX Style Filters, which use an AI technique called style transfer to transform the look and feel of a webcam feed based on the style of another image. With the press of a hotkey, you can style your video feed with your favorite painting or game art.

“The new RTX Broadcast Engine is an exciting advancement that will allow developers in our app store to create powerful new tools for streamers with NVIDIA RTX GPUs,” said Ali Moiz, CEO of Streamlabs. “We’re thrilled to continue working with NVIDIA as they introduce new features to the Streamlabs developer community, and look forward to implementing this new technology.”

“We have collaborated with NVIDIA over the years on many projects and the introduction of the NVIDIA RTX Broadcast Engine is by far the most exciting,” said Miguel Molina, director of developer relations at XSplit. “For the XSplit team, we are excited to integrate these new tools into our suite of apps, enabling our users to create better content by maximizing the potential of NVIDIA GeForce RTX.”

In addition to RTX Broadcast Engine, leading applications such as OBS, XSplit, Huya, Douya and Streamlabs have deployed the NVIDIA Video Codec SDK for fast, high-quality streaming. Three new integrations made their debut this month:

  • Twitch Studio, a new, easy-to-use application for new livestreamers currently in beta, has integrated the Video Codec SDK to enable high-quality livestreaming.
  • Discord, the world’s leading gaming chat application, just released a new group broadcasting feature called “Go Live,” which uses NVIDIA GPUs and the Video Codec SDK to accelerate broadcasting games in Discord.
  • Elgato is one of the world’s leading manufacturers of video capture cards for gaming. It recently integrated the Video Codec SDK into the software of its new 4K60 Pro MK.2 capture card for recording 4K at 60fps video in High Dynamic Range.

An early integration of RTX Greenscreen, along with a host of other demos, will be on display in the OBS Booth (#1823) at TwitchCon this weekend.
