Camera Replacement refers to modifying the content of a specified camera and replacing it with the video content you want to play.
Note: This feature only replaces video content and cannot modify the camera’s resolution. Therefore, low-resolution cameras will not produce high-quality video even after replacement.
Virtual video software (e.g., VCam or WeCam) can simulate a webcam on your computer and use images or videos as the camera’s content for other applications. In theory, any program that uses cameras can work with our virtual camera. However, some programs may only support hardware cameras, block virtual cameras intentionally, or use methods to disable virtual cameras, preventing them from functioning.
WeCam software’s “Camera Replacement” technology solves this challenge.

Camera Replacement
In WeCam, navigate to Output > Camera Replacement to replace the content of another camera with the images or videos playing in WeCam.
1. Enable Replacement
The replacement feature is disabled by default. To use it, first click the Enable button to install the required drivers.
- Close all software using cameras before enabling, otherwise a system restart may be required.
- On Windows 7, install the KB3033929 update to avoid driver signature issues.
- On Windows 10/11, install the latest system updates to prevent driver-related problems.
- If you see “The specified service has been marked for deletion”, restart your computer and try again.
2. Select Camera to Replace
After enabling, the camera dropdown will list replaceable cameras. Select the target camera to replace its output with WeCam’s content. Choose “None” to stop replacement.
If the list remains empty and your camera shows a yellow exclamation mark in Device Manager, its properties may display an error like “Windows cannot verify the digital signature for this driver. Recent hardware/software changes might have caused unsigned or corrupted files. (Code 52)”. This relates to driver signatures. On Windows 7, ensure the system is original and update KB3033929. Disable security software (e.g., 360) that may block driver installation. If needed, you can close the operating system’s driver forcing signatures. For details please search for “disable mandatory signature of the driver” according to your system.
3. Replacement Settings
Configure Mirror, Flip, and Scaling Mode for the replaced video (applied when the camera’s resolution differs from WeCam’s). You can also Pause the replaced camera’s output.
When a replaced camera is in use, its output format and resolution (set by the active program) will display at the bottom. Match WeCam’s project resolution to this for optimal quality.
4. Replace Multiple Cameras
Enable WeCam Multi-Instance and replace different cameras across instances.
5. Disable Replacement
Click Disable button to uninstall drivers. A restart may be required if cameras are in use.
Security software like 360 may cause system crashes during replacement. Disable their camera protection or uninstall them first.
High CPU usage or crashes? Lower the resolution/frame rate in camera apps and avoid MJPG format.
