Drop-frame (DF) timecode skips frame numbers 00 and 01 at the start of every minute, except every 10th minute, keeping TC in sync with real time at 29.97 fps. The frames themselves are never dropped; only the numbering skips. DF TC is written with a semicolon: 01:00:00;00. Non-drop-frame uses a colon: 01:00:00:00.
