How we worked it out
Updated as you change the numbers.
- Photos = clip seconds × fps. Interval = event duration ÷ photos.
Method and assumptions
Faster subjects (people, traffic) suit 1 to 3 second intervals; clouds 3 to 10 s; sunsets and stars 10 to 30 s. The exposure must be shorter than the interval.
Questions
What interval for a 20 s clip of a 2 hour event at 24 fps?
One photo every 15 s: 480 photos.
