frame rate - Computer Definition
In video communications, the rate at which frames of still images are transmitted.Video is a series of still images transmitted in succession to create the perception of fluidity of motion. Motion picture quality is considered to be a frame rate of 24 frames per second (fps) and broadcast television quality is considered to be 30 fps. If the frames are transmitted at a slow rate, the result is a poor quality, herkyjerky video that creates a strobe-light effect. Particularly below 15 fps, quality suffers noticeably, as the fluidity of motion is lost even though the image quality may be high. See also scanning.

Video is captured and played back as a sequence of static (still) images, each image being one "frame." The frame rate is the number of these frames per second. For example, movie film is shot at 24 frames per second (fps), while NTSC video is shot at 29.97 interlaced fps, and high-definition video at 30 and 60 fps. Frame rate conversion is the duplication or reduction of frames in order to display the content on a video device with a different frame rate. See fps.
