Launched OBS Studio 28.0 with 10-bit color support, HDR video encoding and Qt 6 port


OBS Studio 28.0 was officially released today as a huge update to this powerful and popular screencasting and streaming software which introduces many new features and a revamped interface based on the latest Qt technologies.

Highlights of OBS Studio 28.0 include 10-bit color support, HDR video encodinga new color format and color space settings to allow you to change these options in the advanced settings, as well as a port to the latest Qt 6 application framework for a more modern interface with a new default theme called “Yami”.

The P010 color format and the Rec. 2100 PQ settings are recommended for HDR, and P010 color format with SDR color space for 10-bit SDR encoding. HDR streaming will only be supported via YouTube’s HLS service with an HEVC encoder, but it does support video capture devices, and 10-bit encoding requires an AV1 or HEVC encoder. 10-bit HEVC encoding requires NVIDIA 10 series, AMD 5000 series or newer GPU.

Other interesting changes include support for sending chat messages to YouTube from OBS, obs-websocket 5.0 as a proprietary plugin, native SRT/RIST outputs, ability to automatically split recordings into depending on file size or duration, and a new “Accessibility” in the settings to allow you to change the colors of certain UI elements. Linux users also get a new “What’s New” dialog.

OBS Studio 28.0 also brings many improvements like EGL rendering on Linux for better experience, support for H.264 format in Linux V4L2 source (video capture device), multi-view layouts without preview and program, possibility to relatively center multiple sources, the ability to reset the entire interface, a new option for low latency audio buffering, and support for custom FFmpeg options in media sources.

Due to porting to the latest Qt 6 framework, OBS Studio is no longer supported on 32-bit operating systems, nor on Ubuntu 18.04 LTS (Bionic Beaver) systems, which do not offer Qt packages 6. Also, HDR preview does not work on Linux systems at this time, and several inputs/encoders still need to be updated.

You can install OBS Studio 28.0 right now as a Flatpak application from Flathub. For those wishing to compile their own software, the source tarball is also available for download now from the project’s GitHub page. Many bugfixes are included in this release, so see the full release notes for more details.
