OBS Studio 28.1 Beta 1 Changelog:

Added NVENC AV1 hardware encoder on Windows

• Currently only works with NV12 (OBS default) and P010 color formats
• Currently does not support “rescale” function in advanced output mode
• Only available and shown for NVIDIA RTX 40 series video cards
• Available in single output mode for recording (Beta note: Please test this to ensure quality is as expected for “high” and “indistinguishable”! I can tweak internal quality coefficients if needed.)

Updated NVENC Presets

• Presets have been split into 3 different settings: Preset, Tuning and Multipass Mode
• The presets are now P1-P7, with lower numbers being lower quality, higher numbers being higher quality. Note that higher presets may result in higher GPU usage, which could impact the performance of games running concurrently with OBS. The number of concurrent NVENC encoding sessions may be lower when using the higher presets. OBS will automatically map your current NVENC settings to the nearest preset when upgrading.
• The setting 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 the encoding and has three settings: Off, Quarter resolution, and Full resolution. Enabling this option will result in better quality at the cost of increased GPU resource usage.

Other Changes/Fixes

• Fixed a bug where Direct3D 9 games stopped capturing correctly 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
