How Long Is a Time Lapse?
Final video length = recording time ÷ interval ÷ frame rate. Record for 8 hours at one photo every 5 seconds and you capture 5,760 frames — 30 frames a second on playback, so 3 minutes 12 seconds of video. Every number below is worked at 30 fps, the standard playback rate, and every chart runs in both directions: how long your clip will be, and how long you need to record to get the clip you want.
The formula
Three numbers decide the length of a time lapse: how long you record, how often the camera takes a frame, and how fast those frames play back.
Final video length = recording time ÷ interval ÷ frame rate. Divide the recording time by the interval to get the frame count, then divide the frame count by the playback frame rate to get the clip length.
Worked example: 8 hours of recording is 28,800 seconds. At one photo every 5 seconds that is 5,760 frames. At 30 fps those frames play for 192 seconds — 3 minutes 12 seconds.
Run it backwards when you know the clip you want: recording time = clip length × frame rate × interval. A 30-second clip at 30 fps is 900 frames; at a 5-second interval that is 4,500 seconds of recording, or 1 hour 15 minutes.
Chart: minutes-to-hours shoots
Rows are how long you record, columns are the capture interval, and each cell is the finished clip at 30 fps.
| Recording time | 1 s | 2 s | 5 s | 10 s |
|---|---|---|---|---|
| 10 min | 20 s | 10 s | 4 s | 2 s |
| 30 min | 1 m 0 s | 30 s | 12 s | 6 s |
| 1 hour | 2 m 0 s | 1 m 0 s | 24 s | 12 s |
| 3 hours | 6 m 0 s | 3 m 0 s | 1 m 12 s | 36 s |
| 8 hours | 16 m 0 s | 8 m 0 s | 3 m 12 s | 1 m 36 s |
The pattern to internalize: halving the interval doubles the clip. If a shoot comes out too short, shorten the interval rather than recording longer.
Chart: days-to-a-year shoots
Same layout, longer intervals — the range a construction, renovation, or garden shoot lives in. These assume the camera runs around the clock across the whole recording time.
| Recording time | 1 min | 5 min | 15 min | 30 min |
|---|---|---|---|---|
| 1 day | 48 s | 10 s | 3 s | 2 s |
| 1 week | 5 m 36 s | 1 m 7 s | 22 s | 11 s |
| 30 days | 24 m 0 s | 4 m 48 s | 1 m 36 s | 48 s |
| 90 days | 1 h 12 m | 14 m 24 s | 4 m 48 s | 2 m 24 s |
| 1 year | 4 h 52 m | 58 m 24 s | 19 m 28 s | 9 m 44 s |
Real shoots are not round the clock
A build runs 7am to 5pm on weekdays, not 24/7, and the frames have to fit on a card. Give the calculator your schedule and it returns the exact interval, frame count, storage size, and final length for your shoot — not a chart row near it.

At 30 fps a 30-second clip is 900 frames, so the interval decides how much real time you have to cover.
| Interval | Record for |
|---|---|
| 1 s | 15 minutes |
| 5 s | 1 h 15 m |
| 30 s | 7.5 hours |
| 1 min | 15 hours |
| 5 min | ~3 days |
For a 60-second clip, double everything in the right-hand column.
Why your phone ignores all of this
iPhone and most Android camera apps pick the interval for you and thin out frames as the recording grows, so the output usually lands somewhere around 20 to 40 seconds however long you shoot. Behavior varies by phone and software version, so treat that as a rough expectation rather than a rule.
The charts above apply to cameras where you set the interval yourself — GoPro, Brinno, Afidus, or a DSLR on an intervalometer.
FAQ
How long is a 30 second time lapse in real time?
A 30-second clip at 30 fps playback is 900 frames. That is 15 minutes of real time at a 1-second interval, 75 minutes at a 5-second interval, and 7.5 hours at a 30-second interval.
How long is a 1 minute time lapse in real time?
A 1-minute clip at 30 fps playback is 1,800 frames: 30 minutes of real time at a 1-second interval, 2.5 hours at a 5-second interval, and 15 hours at a 30-second interval.
How long is a 5 minute time lapse?
A 5-minute clip at 30 fps playback is 9,000 frames: 2.5 hours of real time at a 1-second interval, and 12.5 hours at a 5-second interval.
How long is a 10 minute time lapse video?
A 10-minute clip at 30 fps playback is 18,000 frames: 5 hours of real time at a 1-second interval, and 25 hours at a 5-second interval.
How long would an 8 hour time lapse be?
Recording for 8 hours gives a 16-minute clip at a 1-second interval, 3 m 12 s at a 5-second interval, and 32 seconds at a 30-second interval — all at 30 fps playback.
Planning something longer?
Length is the easy half. The rest — power, mounting, interval, and turning thousands of frames into a video worth watching — is the long-term guide. When the frames are on your drive, Tweedia Studio trims the stillness, fixes flicker, and exports.
