Frame rate

Drop-frame skips the timecode labels ;00 and ;01 at the start of every minute except every tenth. No frames are lost — only the numbering changes, so the clock keeps up with real time. Drop-frame timecodes are written with a semicolon.

Operation

How it works

1Pick the frame rate you are working at — note that 29.97 has separate drop-frame and non-drop entries.

2Choose whether you are adding, subtracting or converting between rates.

3Type timecodes as HH:MM:SS:FF; short forms like "1:15" are read right-aligned.

4The result shows frames and real elapsed time alongside the timecode.
