Date Sep. 12, 1985.A method for editing and splicing color videograms. A first video tape machine records videogram sequences contained on a video tape in a second machine. The sequence includes a first frame series terminated with a final frame and a second frame series which begins with a first frame. A discontinuity between the first and second frames is detected when the chrominance coding of the adjacent recorded frames is found to be the same instead of on an alternate basis. Each frame of the second frame series is shifted under these conditions in order that each video line subsequent to the first video line is shifted forward. The first video line is reduced to a black level. The method avoids the consequences of a splice between groups of frames when the frames on each side of the splice do not have the required opposite chrominance coating.
