Software Update: OBS Studio 28.1 Beta 1

Version 28.1 of OBS Studio is in development and the first beta release has been released. Open Broadcaster Software Studio is open source and cross-platform software intended for recording and streaming video from one or more sources, such as a webcam, microphone, media files, and the desktop. In version 28, support for 10-bit and HDR video encoding has been added, a version for Apple hardware has been equipped with an Apple Silicon CPU and the switch has been made to Qt 6 for the user interface. The following improvements have also been made in version 28.1:

28.1 Changes

• Added NVENC AV1 hardware encoder on Windows
  • Currently only works with the NV12 (OBS default) and P010 color formats
  • Currently does not support the “rescale” feature in advanced output mode
  • Only available and shown for RTX 40 Series video cards from NVIDIA
  • Available in simple output mode for recording (Beta note: please test this to make sure the quality is as expected for “high” and “indistinguishable”! I can tweak the internal quality coefficients if needed.)
• Updated NVENC presets
  • Presets have been split into 3 different settings: Preset, Tuning, and Multipass Mode
  • Presets are now P1-P7, lower numbers being lower quality, higher numbers being higher quality. Note that higher presets may incur higher GPU usage which could impact the performance of games running simultaneously with OBS. The number of simultaneous NVENC encoding sessions may be lower when using the highest presets. OBS will automatically map your current NVENC settings to the closest preset when upgrading.
  • Tuning is used to determine whether to prioritize latency or quality. It has three settings: High Quality, Low Latency, and Ultra Low Latency.
  • Multipass Mode is used to determine whether a second pass is used in encoding, and has three settings: Disabled, Quarter Resolution, and Full Resolution. Enabling this will give higher quality at the cost of more GPU resource usage.
• Fixed a bug where Direct3D 9 games stopped capturing properly with game capture on Windows 11 22H2
• Moved “Always on Top” to the View menu
• You can now select a specific source for the Virtual Camera
