What is a Timecode Calculator?
Every video frame has an address like 01:23:45:12 — meaning 1 hour, 23 minutes, 45 seconds, and 12 frames. Video editors use timecode calculators for:
Calculate Total Runtime
"I have 5 clips. What's my total duration?" — add all timecodes together.
Find Edit Points
"Client wants 30 seconds cut. If I start at 00:02:15:00, where do I end?" — subtract to find out.
Calculate Duration
"How long is the section from 00:05:30:00 to 00:08:45:12?" — use the Duration Calculator above.
Convert Frame Rates
"I shot at 24fps but delivering at 29.97fps. What's the new timecode?" — use Frame Rate Converter.
