frame rate 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, herky-jerky 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. |
