Virtual camera

  1. Click the camera button in the top bar.
  2. In your call app, choose Clutch Virtual Camera as the camera. Windows lists it as Clutch Virtual Camera (Windows Virtual Camera).

Choose which canvas it shows in Settings → Virtual camera. While no app is using the camera, it costs nothing.

Windows

Section titled “Windows”

The virtual camera needs Windows 11. The installer registers it, so it’s ready right away. If it doesn’t show up in an app, use Settings → Virtual camera → Reinstall (Windows asks for permission once) and restart the call app.

Linux

Section titled “Linux”

Clutch writes to a v4l2loopback device. Install and load it with a name call apps will show:

Terminal window
sudo apt install v4l2loopback-dkms      # or your distribution's package
sudo modprobe v4l2loopback card_label="Clutch" exclusive_caps=1

To load it at every start, put v4l2loopback in /etc/modules-load.d/v4l2loopback.conf and options v4l2loopback card_label="Clutch" exclusive_caps=1 in /etc/modprobe.d/v4l2loopback.conf.
