After recording, I cannot see the webcam in the recording preview, why is this?
The webcam is on the lower right-hand corner of the recording preview. If you cannot see it, scroll to the bottom right-hand corner or click Shrink to Fit.
You will notice that the webcam preview is relatively small. If you have set the correct resolution for the webcam (1280 x 720) before recording, you will be able to expand the webcam capture to these dimensions during editing.
