ABSTRACT:
A video tape editing technique in which video information recorded on a first magnetic tape is edited and recorded on a second magnetic tape in a selected order. The technique includes playing back video information recorded on a first magnetic tape and displaying the played back information on a video monitor. The start and end fields or frames of edited segments of video information on the first magnetic tape are designated. Upon designating the start field or frame of an edited segment, at least a portion of such field or frame is stored in reduced format in memory and simultaneously the location of such start field or frame is also stored in memory. Upon designating the end field or frame, its location is also stored in memory. After all of the edited segments have been designated, the reduced format portions are read from memory and displayed in a matrix on the video monitor and the order in which the designated segments of video information are to be recorded on a second magnetic taqpe are selected from the matrix display. Thereafter, playback of the first magnetic tape is controlled so that the designated segments of video information are sequentially recorded on a second magnetic tape in the selected order.
