The basic formula
At 30 frames per second, 1,800 frames represent 60 seconds of frame duration. For the reverse calculation, 45 seconds × 30 FPS equals 1,350 frames. The result may need rounding to a whole frame.
Use the frame rate and timecode calculator to try different frame counts and rates.
Common frame-rate examples
| Duration | 24 FPS | 30 FPS | 60 FPS |
|---|---|---|---|
| 10 seconds | 240 frames | 300 frames | 600 frames |
| 30 seconds | 720 frames | 900 frames | 1,800 frames |
| 60 seconds | 1,440 frames | 1,800 frames | 3,600 frames |
These examples use whole-number frame rates for straightforward arithmetic. Rates such as 23.976 and 29.97 are fractional approximations and can create small differences over longer durations.
Frames, FPS, and timecode are different
FPS is the rate at which frames are displayed or recorded. A frame count is simply a number of frames. Timecode is a way to label positions using hours, minutes, seconds, and frame numbers. Some professional workflows use drop-frame timecode numbering to keep a 29.97 FPS timecode clock aligned with elapsed clock time; it does not physically drop video frames.
For a broader explanation of rate choices, read 24 vs 30 vs 60 FPS. For storage estimates, use the video file size calculator.
Frequently asked questions
How many frames are in one minute at 30 FPS?
Using simple constant-rate arithmetic, 60 seconds × 30 frames per second equals 1,800 frames.
Why does 29.97 FPS timecode look different?
29.97 is a fractional rate. Professional timecode may use drop-frame numbering to align the displayed time with elapsed clock time.
Can frame count alone tell me the duration?
You also need the frame rate. The same frame count represents different durations at different FPS values.
