Greater care is necessary when producing segments where this is a concern, as improper settings when capturing a segment can cause audio to lag behind or speed ahead of the displayed video. Frames of video may also be omitted which creates noticeable gaps. This is often due to the recording software's inability to keep up with the VCR's video input.
