How to calculate the shooting interval in time-lapse photography

What exactly is your minute? Is it shooting time or video time?

If it's shooting time, take one shot every 5 seconds, and only 60/5+1 =13 shots per minute; If you shoot one every two seconds, you have to shoot 60/2+ 1=3 1. If you do video according to 24 frames, the former can only do half a second, and the latter can do more than one second.

On the other hand, if you make a video with a total duration of 1 min according to 24 frames, you need to take 24*60= 1440 photos. If you take a photo every 5 seconds, it will take about 120 minutes. If you take a picture every 2 seconds, it only takes 48 minutes. It can also be said that the former condensed two hours of scene changes into one minute, while the latter condensed less than one hour into 1 minute. Although both videos are 1 minute long, the time and flow rate in them are much different.
