When to use Timecode calculator
- You need the frame number of a timecode before you set a cut in your editor.
- You want to know how many seconds 1,800 frames are at 23.976 fps.
- You know the length of part 1 and need the timecode where part 2 starts.
- You must check a drop-frame timecode such as 01:00:00;00 against real time.

Common questions
How do I convert a timecode to frames?
Change the hours, minutes, and seconds to seconds, multiply by the frame rate, and add the frames. At 25 fps, 00:01:00:00 is 1,500 frames.
How do I convert frames to seconds?
Divide the frames by the frame rate. 1,800 frames at 30 fps are 60 seconds. For 23.976 fps, use 24000 divided by 1001 as the rate.
What is drop-frame timecode?
Drop-frame timecode skips the numbers 00 and 01 at the start of each minute, except every tenth minute. No picture is dropped. The skip keeps 29.97 fps timecode close to the clock on the wall.
Why is 23.976 timecode different from real time?
Timecode at 23.976 counts 24 frames for each second, but the video plays 24 frames in 1.001 seconds. One hour of timecode is 3,603.6 seconds of real time.
Which frame rate should I choose?
Use the rate of your video file. Film often uses 23.976 or 24. PAL video uses 25. NTSC video uses 29.97. Your video player can show the rate in its file information.
Can I use this for subtitle times?
Subtitle files use hours, minutes, seconds, and milliseconds, not frames. Convert your frame timecode to seconds here, and use the seconds in a subtitle tool.
Is my file uploaded?
No. The tool runs in your browser. Your subtitle file never leaves your computer.
