Video Time Calculator
Timecode to Frames Calculator
Convert SMPTE timecode to total frames, frames back to timecode, and calculate IN/OUT duration for editing, animation, VFX, YouTube videos, and post-production work.
Example: 00:01:00:00 at 24 fps = 1,440 frames
Convert timecode and frames
Enter a timecode like 00:01:30:12, choose FPS, and get the exact total frame number. You can also enter frames to convert back to timecode.
Step-by-step calculation
00:01:30:12 = 90 seconds × 24 fps + 12 frames = 2,172 total frames
IN/OUT duration calculator
Calculate the frame difference between two timecodes. This is useful for clip length, animation timing, render ranges, and edit notes.
How to convert timecode to frames
Timecode is usually written as HH:MM:SS:FF. The first three parts show hours, minutes, and seconds. The final part shows the frame number inside that second.
Formula: total frames = ((hours × 3600) + (minutes × 60) + seconds) × fps + frames
Example: 00:01:30:12 at 24 fps = (90 × 24) + 12 = 2,172 frames
For regular calendar-style time calculations, you may also like the age calculator. If you are comparing two dates instead of two video timecodes, use the days between dates calculator.
Timecode to frames examples
| Timecode | FPS | Total frames |
|---|---|---|
| 00:00:10:00 | 24 fps | 240 frames |
| 00:01:00:00 | 24 fps | 1,440 frames |
| 00:05:30:12 | 30 fps | 9,912 frames |
| 01:00:00:00 | 25 fps | 90,000 frames |
| 01:31:50:18 | 24 fps | 132,258 frames |
What is this timecode calculator useful for?
This calculator is useful for video editors, filmmakers, animators, subtitle editors, motion designers, VFX artists, and anyone who needs frame-accurate timing. It can help with render ranges, edit decisions, animation timing, subtitle placement, audio sync notes, and frame-based production planning.
The tool is intentionally simple and fast. It avoids heavy JavaScript, but still gives practical results such as total frames, timecode, seconds, FPS, and IN/OUT duration.
Important note about drop-frame timecode
This calculator uses straightforward non-drop-frame style math. That works well for many editing and animation tasks, especially when you need a simple frame count from a timecode. Some broadcast workflows use drop-frame timecode at rates such as 29.97 fps to keep clock time and timecode closer over long durations. For those workflows, check your editing software settings before using any result as a final delivery value.
Frequently asked questions
How do you convert timecode to frames?
Convert hours, minutes, and seconds into total seconds, multiply by the frame rate, then add the frame value. For example, at 24 fps, 00:01:00:00 equals 1,440 frames.
What does HH:MM:SS:FF mean?
HH:MM:SS:FF means hours, minutes, seconds, and frames. The final FF value is a frame count inside the current second, not milliseconds.
Can I convert frames back to timecode?
Yes. Enter the total frame count in the frames box and the calculator will convert it back into HH:MM:SS:FF format using your selected frame rate.
Which frame rates does this calculator support?
The calculator includes common presets such as 23.976, 24, 25, 29.97, 30, 50, 59.94, and 60 fps. You can also enter a custom frame rate.
Does this calculator support drop-frame timecode?
This tool is designed for simple non-drop-frame style calculations. For broadcast drop-frame workflows such as 29.97 DF, use the result as an estimate unless your editing workflow confirms the same counting method.
