Video is the technology of electronically capturing, recording, processing, storing, transmitting, and reconstructing a sequence of still images representing scenes in motion. The common name of a motion picture is 'video film', or shortly 'video'. The quality of a video depends on various factors. VideoFrame rate is the number of still pictures per unit of time of video. The bigger this number is, the better the quality. For digital videos the size of the video image is measured in pixels. To this size the term of 'aspect ratio' is connected. Aspect ratio describes the dimensions of video screens and video picture elements. It is a ratio between width and height.
