how do you calculate a time lapse?

real time = video length × frame rate × capture interval. a 30-second video at 30 fps is 900 frames; captured every 2 seconds, those 900 frames took 30 minutes to record. rearrange the same formula to get video length (recording time ÷ interval ÷ fps) or the interval you need (recording time ÷ video length ÷ fps).

how long is a 30-second time lapse in real time?

it depends on the capture interval. at 30 fps, a 30-second timelapse is 900 frames: 15 minutes of real time at one frame per second, 30 minutes at one every 2 seconds, and 2.5 hours at one every 10 seconds.

how long is a 30-minute video in time lapse?

thirty minutes of recording becomes 60 seconds of video at one frame per second and 30 fps, 30 seconds at one frame every 2 seconds, and 12 seconds at one every 5 seconds.

how long will a 1-hour time lapse be?

an hour is 3,600 seconds. divide by the interval to get frames, then by the frame rate to get video length. one frame every 2 seconds gives 1,800 frames, which is 1 minute of video at 30 fps or 1 minute 15 seconds at 24 fps.

what interval should i use for a time lapse?

work backwards from how long you want the finished video to be: interval = recording time ÷ (video length × fps). fast-changing scenes suit 1–3 seconds; slow ones, 5 seconds or more.

does frame rate change how much time a timelapse shows?

not the time captured, only how fast it plays back. the same 1,800 frames last 1 minute at 30 fps and 30 seconds at 60 fps. a higher frame rate gives a shorter, faster video.
