What camera interval gives me the time-lapse length I want?
Multiply playback seconds by frame rate and round up to a whole number of frames. The first shot begins at the start and the last begins at the end, leaving one fewer interval than frames. Divide capture seconds by that interval count. Negative clear time means the camera cycle is too long.
