Remarks
Drop-frame mode is used in NTSC video to correct the discrepancy between the video, which is 29.97 frames per second, and the time code display, which is 30 frames per second. In drop-frame mode, frame numbers 00 and 01 are skipped at the start of each minute, except for minutes that are even multiples of ten (00, 10, 20, and so forth). Only the frame numbers in the time code are dropped; no actual frames are dropped.
