When the device is connected incorrectly or the device driver is installed improperly,
you may see the ‘Failed to initialize the video capture device’ error message in the Device Recording Mode.
How to solve this problem
1. Check if there is a conflict with another webcam/capture program.
In Windows, only one webcam/capture device can be used in one program. If another webcam (or capture program) is running, you must first close the webcam (or capture program) before running Bandicam.
2. Please reinstall the latest version of the webcam/capture device driver.
3. Turn off the “Use custom audio device” option and try again.
4. Select another video size from the format selection menu.
5. Check the connection of the webcam or capture device.
