Sunrise parameters of camera time-lapse photography

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.
