This table is for 24 fps; to convert to 30 fps multiply the time and the distance by 0.8.

For example, for 12 frames the time fallen is 0.4 seconds and the distance fallen is 3.2 feet.

The formula to compute the distance fallen (for 24 fps) is:

(Distance in inches) = (Number of Frames) x (Number of Frames) x (1/3 inch)

To convert to 30 fps, multiply the calculated distance by 0.8.
