Abstract

To improve the efficiency of primary editing of a video tape, a shot mark as a mark at the time of primary editing is determined. With a video tape of a digital VTR format, the shot mark may be recorded onto a user'"'"'s bit on a time code track. Even at the time of editing, this shot mark may be appended. At the time of primary editing, a predetermined range specified with reference to the position of the shot mark is defined as a portion to be used, thereby preparing a master tape.
