How Many Photos Do You Need for a Progress Timelapse?
The maths of a timelapse made from daily photos: how long 30, 75, 90 and 365 photos last at different frame rates, and which speed looks best.
The rule is one line: video length in seconds = number of photos ÷ frames per second.
So 60 daily photos at 10 frames per second make a 6-second video. The only real decisions are how many photos you take and how fast you play them.
How long do daily photos last?
| Days of photos | 6 fps | 10 fps | 12 fps | 24 fps |
|---|---|---|---|---|
| 30 | 5 s | 3 s | 2.5 s | 1.3 s |
| 75 | 12.5 s | 7.5 s | 6.3 s | 3.1 s |
| 90 | 15 s | 9 s | 7.5 s | 3.8 s |
| 180 | 30 s | 18 s | 15 s | 7.5 s |
| 365 | 61 s | 36.5 s | 30.4 s | 15.2 s |

Which frame rate looks best?
For progress photos, 6 to 12 frames per second is the sweet spot. Each day stays on screen long enough to register, but the sequence still flows. At 24 fps and above, day-to-day changes blur into noise and you lose the effect.
How long should the video be?
Short-form video platforms favour clips of roughly 7 to 30 seconds. That means:
- 30 to 75 days: play at 8 to 12 fps for a 3 to 9 second loop. Great as a looping Reel.
- 90 to 180 days: 10 to 12 fps lands at 8 to 18 seconds.
- 365 days: 12 fps gives about 30 seconds, ideal for a year-in-review.
Too many photos? Sample them
You do not have to use every photo. If you took photos for 365 days but want a 12-second video, use every third day. Safar's reels do this for you: when your date range holds more photos than the style can show, it takes them evenly from the first day to the last, so the whole stretch appears.
Tips for a smooth timelapse
- Keep the framing the same. A fixed spot and distance is what makes the transformation pop.
- Keep the light similar. Flickering exposure is the most common reason timelapses look rough.
- Shoot at the same time of day where you can.
- Do not skip the first and last days. They are the comparison your viewer cares about.
