Table 3: An example of the representative video, audio, and control-track times, lengths, and frames for a 20.00-second overrecording with the following characteristics: (1) the underlying recording is at SP speed (2) the overrecording is at EP speed, and (3) the underlying recording and overrecording VCRs have hi-fi audio heads, but the overrecording unit does not have a flying erase head. The distance from the full-track erase head to the video-recording head has been designated as 80.00 mm, the frame numbers have been rounded to the nearest whole number, all lengths are in mm, and all times are in seconds.
