ABSTRACT:
A video editing apparatus which can perform editing in units of frames with respect to video data encoded by GOPs using inter-frame correlation, in which video data recorded on an MO disc drive is decoded by an MPEG decoding unit and a predetermined frame of the decoded video data is substituted with other video data selected by a switch. The new video data including also the pictures of the frames before and after this is subjected to re-encoding at the MPEG encoding unit in a state where the original GOP frame structure before editing is maintained based on the signal indicating the punctuation of GOP input from the MPEG decoding unit and is recorded on the MO disk drive.
