OBS Studio News

• Fixed NVENC preset not being migrated properly in simple output mode [RytoEX]
  
• Fixed the inability to start the encoder when NVENC is set to a bframe count higher than is supported by the device [RytoEX]
  

OBS 28.1 is now available, this is a minor update for 28.0 introducing support for AV1 encoding via NVIDIA NVENC as well as a few bug fixes.

[h3]Note for macOS users:[/h3]
Starting with this update M1/M2 Macs will run the ARM/"Apple Silicon" version of OBS by default.
This may lead to some plugins or VST effects not being loaded due to not being Apple Silicon compatible, so make sure to check for plugin updates.
To keep using the x86/Intel version of OBS add the "--intel" parameter to "Launch Options" (Right click -> Properties -> Launch Options).

[h2]Changes:[/h2]

• Added NVENC AV1 hardware encoder on Windows [Jim]
  
  • 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 for RTX 40 Series video cards from NVIDIA
    
  
  
  
• Updated NVENC presets [Jim]
  
  • 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 [Rodney]
  
• Moved "Always on Top" to the View menu [gxalpha]
  
• You can now select a specific source for the Virtual Camera [chippydip]
  
• Fixed a crash on resolution change of Windows Virtual Camera [Jim]
  
• Fixed a Discord crash with Windows Virtual Camera [Jim]
  
• Fixed crashes with macOS applications loading the virtual camera [PatTheMav]
  
• Fixed Steam version launching x86_64 version on Apple Silicon devices [Rodney]
  
• Fixed Stats widget appearance issues [tytan652]

• Fixed case where video capture is darkened when both luma wipe and scale filtering are set [rcdrone]
  

[h3]Note for macOS users:[/h3]
Starting with this update Apple Silicon Macs will correctly run the ARM version of OBS by default.
This may lead to some plugins or VST effects not being loaded due to not being Apple Silicon compatible, so make sure to check for plugin updates.
To keep using the x86/Intel version of OBS add the "--intel" parameter to "Launch Options" (Right click -> Properties -> Launch Options).

We have beta build for OBS Studio 28.1 available for testing! This is a minor feature release, focused on NVENC AV1 support and a few smaller bug fixes.

Release Highlights:

• Added NVENC AV1 hardware encoder on Windows [Jim]
