time-lapse video information needed

i have some software that will allow me to make a time-lapse video
with my webcam. I made one today, but it went TOO fast! Does anyone
know how to slow things down? i have it set at 30 frames per second.
it says take 1 frame every (blank) seconds. then it says playback
rate (images per second) is 10. How do i slow things down a bit, but
still have a time-lapse video? what numbers do i need to change?
thanks
