4K Capturing

This section provides information on the settings and considerations for performing 4K capturing with VirtualLens2.

Basic Settings

VirtualLens2 Settings

During setup, enable the “Enable 4K Capturing” option found in VirtualLens Settings under Algorithm Settings.

VRChat Settings

In VRChat, select 4K (2160p) resolution from the Resolution menu in the built-in VRChat camera settings.

Considerations

Behavior When Settings Don’t Align

If the camera resolution in VRChat settings is something other than 3840x2160, VirtualLens2 will attempt to upscale or downscale the rendering results for 1920x1080. As a result, if the resolution is set to something other than 3840x2160 or 1920x1080, the image quality may degrade. Please be mindful of this.

Additionally, when 4K capture is enabled in VirtualLens2, the rendering results for 1920x1080 are slightly lower in quality, as they are intended for preview. Therefore, if the camera resolution setting in VRChat remains at the default (1920x1080), it may be advantageous not to enable the 4K capture option in terms of image quality.

Compatibility with Stream Camera

When using Stream Camera, the camera resolution matches the size of the desktop window. Therefore, without adjusting the window size properly, it may result in image quality degradation as mentioned when settings don’t align. If possible, it is recommended to use VRChat’s startup options to set the window to fullscreen at 3840x2160 (when 4K recording is enabled) or 1920x1080 (when 4K recording is disabled).
