If the Screencast-O-Matic screen recorder crashes (or you only see a static image in the webcam window) when you try to record your webcam, you may have another application installed that's causing a conflict when the recorder tries to use the webcam.
Check to see if you have any of these applications installed which can cause the problem:
- Cyberlink Webcam Splitter
- ASUS Virtual Camera
- Cam Link 4K
If so, you'll need to uninstall them to use the webcam recording feature in the Screencast-O-Matic screen recorder.
Also, please make sure that you have the latest software drivers installed for your webcam.
