    • A video image edit device for editing video image contents recorded on a video tape. The video tape is rewound to its leading end and a start point time code and a maximum video image content period are stored in a RAM. Then, a video reproduction is started and a time code and time information for a video image content are retrieved. A difference between the present time and a precedent time is compared with a predetermined period to detect discontinuity of the video image content. If discontinuity cannot be detected, judgment is made as to whether or not a difference between the present time code and a start point time code exceeds the maximum video image content period to determine a subdivision point. If discontinuity is detected, or if the difference exceeds the maximum video image content period, a present end point time code and next start point time code are stored for again detecting the discontinuity or judging the next subdivision point.
