-
Drop-Frame Timecode
Drop-frame timecode, commonly used in NTSC video (30 fps), compensates for the slight discrepancy between the frame rate and real-time clock. It periodically “drops” frame numbers (specifically, frames 00 and 01 of every minute except for minutes divisible by ten) to maintain synchronization with real-time. Timecode calculators must correctly interpret and manipulate drop-frame timecode to avoid calculation errors. For example, subtracting ten minutes in drop-frame timecode requires the calculator to account for the dropped frames to achieve an accurate result.
-
Non-Drop-Frame Timecode
Non-drop-frame timecode represents a direct count of frames from a starting point, without any frame dropping. Common in film and PAL video (24 fps and 25 fps respectively), this format aligns directly with real-time. Timecode calculators must differentiate between drop-frame and non-drop-frame formats to perform calculations correctly. Misinterpreting the format leads to inaccurate durations and synchronization issues.
-
Real-Time vs. Time-of-Day Timecode
Real-time timecode represents elapsed time from a specific starting point, whereas time-of-day timecode references actual clock time.
