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

Use the timelapse calculator for your own numbers.

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.
