TV video generates 30 interlaced frames per second, which is actually transmitted as 60 half frames per second.
Video that has been digitized and stored in the computer can be displayed at varying frame rates, depending on the speed of the computer. The slower the computer, the more jerky the movement. Contrast with freeze-frame video.
