I would suggest you read the section on importing from analog sources in the PDF manual which should be available under Help - you may have to download it.
In the second image the device is shown as a HP Webcam - if you select the drop down does the Magix Converter appear?
If the converter is not there, with Video Easy closed, in the Windows settings, Privacy option select the Microphone and Camera options and a turn on Allow desktop Apps to access Microphone/Camera.
