How to calculate the delayed photography time?

It depends on how long your final movie will take. If you want to finish broadcasting in one minute, the calculation is as follows:

Suppose the time from sunrise to sunset is 12 hours, which is converted into seconds: 3600* 12=43200 seconds.

Assuming that the movie has 25 frames per second, the number of frames per minute is 25*60= 1500.

43200/ 1500=28.8 (seconds)

That is once every 28.8 seconds. For convenience, you can take a picture every 30 seconds.
