OBS Studio 28.0 Beta 2

28.0 Beta 2 Notes

• Added the ability to use a separate video mix for the virtual camera
• Added a "B-Frames" option to the new AMD encoder for H264 (note that this will only work if your device supports B-Frames)
• Greatly increased the maximum limits of automatic file splitting settings
• Updated a number of icons to better suit Yami
• Fixed a few UI and Yami theme quirks
• Changed the spacer lines to use configurable accessibility colors and be DPI-aware
• Fixed preview tearing on Windows
• Deprecated the previous AMD encoder in favor of the new version
• Reverted faster theme switching, therefore fixing theme switching on macOS
• Fixed a bug where the macOS Screen Capture source would not pick up new windows in Display Capture mode on macOS 12.5
• Fixed a bug where the split file hotkey would appear multiple times in the settings window after changing profiles
• Added HDR support to the NVIDIA Background Removal filter

28.0: 10-bit and HDR Video Encoding Support

OBS now supports 10-bit and HDR, courtesy of rcdrone, YouTube, and Luxoft. New color format and color space settings have been added in the advanced settings to allow this.

Important notes about HDR and 10-bit:

• HDR and 10-bit can only be encoded with AV1 and HEVC encoders.
• The recommended settings for HDR are Color Format P010 and Color Space Rec. 2100 PQ.
• If you wish to encode 10-bit SDR, you can use Color Format P010 with an SDR color space (e.g. Rec. 709, Rec. 601). However, AV1 or HEVC will still be required.
• HDR streaming is currently only supported via YouTube's HLS service via an HEVC encoder.
• When composing in SDR, games that operate in HDR can now be properly tonemapped to SDR.
• Video capture devices can be used to capture and stream in HDR if the device supports it (e.g. EVGA XR1 Pro, Elgato 4K60 Pro Mk.2, AverMedia Live Gamer 4K).
• Certain filters will not function if a source is rendering with HDR:
  • Apply LUT, Chroma Key, Color Key, Image Mask/Blend, Luma Key, Sharpness
• Mac/Linux support is limited. HDR preview does not work, and several inputs/encoders still need to be updated.

28.0: Updating to Qt 6

As of May 2020, version 5 of the Qt user interface toolkit ceased public development and is no longer being updated. Since then, our need for a more up-to-date version has been increasing as time goes by. With version 28.0, we felt it was important for us to update our user interface toolkit to the latest version; not just to gain access to the latest features, but also for the latest bug fixes and improved support for newer operating systems and architectures such as Windows 11 and Apple Silicon. Unfortunately, this also means that certain plugins that depend on version 5 of Qt will no longer work when you upgrade to version 28.0 and will need to be updated.

During this beta period of OBS 28.0, many of those plugins which rely on Qt version 5 may not yet be updated yet, and we'll be working with third-party plugin developers in order to get them updated before the final release deploys.

Additionally, Qt 6 has dropped support for Windows 7 & 8, macOS 10.13 & 10.14, Ubuntu 18.04 and all 32-bit operating systems. As such, OBS will no longer be supported on these platforms.

For more details, please refer to our Discussion Post: Plan to Upgrade OBS Studio to Qt 6.

28.0: Native Apple Silicon Support

With OBS 28, OBS now has native builds for Apple Silicon systems. This means that OBS will run more optimally and without x86 emulation. Unfortunately, an important caveat for this is that many third-party plugins may not yet be readily available for Apple users running native Apple Silicon builds. Users can still use x86 builds of OBS if they desire a wider selection of third-party plugins that are not yet available natively for Apple Silicon.
