At 60 fps, 1 frame lasts for approximately 16 milliseconds. You can go below 16 milliseconds if you align the effect, transition, video, audio or image on a frame boundary. You can find the frame boundary by moving the frame forward or backwards.
Television and Pictures typically play at 25 to 30 frames/second. Video Edit Magic can make movies at 60 frames/second, which is double than the standard playback rate. Beyond 60 frames/second, viewers will not notice any difference. You will unnecessarily increase the file size without getting any viewable differences.
