Key takeaways
- Frames = seconds × frames per second: a minute at 30 fps is 1,800.
- Checked on real files: a 10 second clip at 30 fps has 300 frames, and our GIF maker's 16 GIFs had 0 to 0 frames more than seconds × fps.
Where frame counts matter
Frame counts fix the length of GIFs, the number of images to export from a clip and the work an encoder does. Duration is frames divided by frame rate, so the same frames play longer at a lower rate.
The last row of the results shows the same frames at other rates. It is the quick way to see what happens when footage shot at one rate is played at another.
Scenarios
| Scenario | Total frames | One frame lasts |
|---|---|---|
| 10 seconds at 24 fps | 240 | 41.67 ms |
| 10 seconds at 30 fps | 300 | 33.33 ms |
| 1 minute at 60 fps | 3,600 | 16.67 ms |
| 1 hour at 24 fps | 86,400 | 41.67 ms |
| 5 seconds at 12 fps (a GIF) | 60 | 83.33 ms |
Measured: GIF frame counts
The video to GIF tool writes a GIF at the frame rate of its preset. We counted the frames of each result.
| Preset or setting | Seconds × fps | Frames in the file |
|---|---|---|
| Small preset | 50 | 50 |
| Balanced preset | 60 | 60 |
| Sharp preset | 75 | 75 |
| grid 320 px 8 fps | 40 | 40 |
| grid 320 px 12 fps | 60 | 60 |
| grid 320 px 15 fps | 75 | 75 |
| grid 480 px 8 fps | 40 | 40 |
| grid 480 px 12 fps | 60 | 60 |
