Timecode calculator
Convert HH:MM:SS:FF timecode to seconds and back at any frame rate. Frames are not decimals, which is why timecode arithmetic done by hand usually goes wrong.
- Timecode as seconds
- 90.400 s
- Timecode as frames
- 2,712
- 90.4 s as timecode
- 00:01:30:12
- Frame duration
- 33.33 ms
At 30 fps. A frame number is never larger than fps − 1.
Drop-frame timecode (29.97) renumbers frames rather than changing their length; this calculator is non-drop.
Calculated as: seconds = h×3600 + m×60 + s + frames ÷ fps
What this assumes
- Non-drop-frame only. Broadcast 29.97 drop-frame timecode skips frame numbers and will not match these figures.
- Assumes a constant frame rate.
Koldflux works these numbers out for you when it exports - the calculators exist because our own pipeline needed them first.
