OBS Studio 31.0.0 Beta 1 is now available, with new features like NVIDIA Blur Filter and Background Blur, preview scrollbars, v210 format support for AJA device capture, Amazon IVS service integration, QSV AV1 Screen Content Coding, and first-party YouTube Chat.

Changes include updating the browser source/docks CEF to version 127 (6533) on all platforms, changing scene items to use relative coordinates, splitting NVIDIA audio effects from noise suppression, changing the Image Slideshow's Playback Mode property from radio buttons to a dropdown, disabling the built-in Automatic Scene Switcher when using Wayland on Linux, improving error messages for macOS Virtual Camera, and changing display and window capture on Windows and Linux. The NVENC implementation has been refactored with several improvements, and new functionality from previous SDKs are now supported. Bug fixes include two Linux crashes with the QSV encoder, a race problem with multitrack video output reconnect, MP4 muxer deadlocks, potential memory failures, buffer overruns during UTF-8 text conversion, and audio clipping indicator issues.

OBS Studio 31.0.0 Beta 1

Note: NVIDIA Kepler GPUs are no longer supported for NVENC.

Note: NVIDIA users may need to update their GPU drivers to 551.76 (Windows) / 550.54.14 (Linux) or newer.

Note: The code signing certificate for OBS is being updated. This may impact game capture compatibility with some anti-cheat solutions starting with the next major OBS update.
