How+Frame+Rate+Affects+Film+Smoothness

JT M   Cary Academy ** ABSTRACT  ** The purpose of this experiment was to see how many frames per second could be removed from a video clip before anyone noticed the change in the smoothness of motion and quality of the clip. It was hypothesized that one could remove as many as 30 frames per second (fps) without the observer noticing a major change in the smoothness. Using a high definition camcorder, a video clip of a boy playing soccer was recorded. The video clip was put into a video software program, Final Cut Pro. This program allowed one to see the individual frames of the video clip. Frames were removed to change the frames per second from 60 fps to 30 fps, 20 fps, 15 fps, 10 fps, and 6 fps. Eight observers watched the video clips without knowing the number of frames per second. The observers then rated the individual clips. Most observers did not notice a large difference in smoothness between the 60 fps and 30 fps clips, however, the 60 fps clip did rate higher.
