1) Drop-frame/non-drop-frame mode: In the NTSC system, the actual frame rate is 29.97 frames per second. There is therefore a cumulative discrepancy between the actual frame rate and the 30 frames per second rate on which time code is based. In drop-frame mode, except once every 10 minutes, the first two frames are skipped at the beginning of each minute to keep the time code values in step with actual elapsed time. In non-dropframe mode, the correction is not carried out, and there is a discrepancy of about 86 seconds per day between actual elapsed time and time code values.
