A video edit which starts on the first frame of the 5 video frame (4 film frame) sequence created when 24-frame film is transferred to 30 frame. The A-frame is the only frame in the sequence where a film frame is completely reproduced on one complete video frame. Here is the full sequence. (The letters correspond to the film frames.) A-frame = video fields 1&2, B-frame = video fields 1&2&1, C-frame = video fields 2&1, D-frame = video fields 2&1&2.
