I'm sorry, I passed over that program because I thought it was mac or smartphone or something! It's a start, because now I've played with it, I can see that the timers are chained dividers from the main clock (in my case it's 2,880,000Hz) so the frame rate is
FPS = 2,880,000 / (timer A * timer B)
Apart from giving me that information, the program seems to be focused on getting an exact frame rate, which doesn't seem important to me at the moment, since no one's going to know if your timelapse movie is shot at 3x speed or 3.1x speed... but I digress.
Remaining questions are:
What is the difference between timer A and timer B, if any?
What controls the shutter speed?
What controls the jello effect? (I know what causes it, what controls it?)
When you increment the timer values, sometimes they show "(FT + nnn)" where 'nnn' increases and decreases with the value, implying that "FT" is a constant. What is "FT"?
From the program, it appears that Timer A goes up to 8192, and Timer B goes up to 16384, is that right?
The program gives values for Timer B that are always bigger than Timer A. Why?
Thanks
