Watch the program on a computer or using a DVD player. The program must be watched on something that can pause and rewind.
Watch the program and count the length of time between cuts. The program will have many cuts. A cut is when the images switch from one camera to another. For example, from one character to another. You must be accurate with your counting, as the cuts will be quick. Rewind and recount if you missed something.
Total up the times of the different cuts at the end of the program. For example, the number of cuts less than one second, the number of one-to-two second cuts, two-to-three second cuts and so on.
Compare the number of cuts to each other. For example, 300 two-to-three second cuts, 200 three-to-four second cuts. This data will tell you a lot about the pacing. If the majority of cuts are short, then the pacing is probably fast. If the cuts are longer, then the pacing is likely slower.
