ABSTRACT:
A video clip is processed by selecting a plurality of video frames of the video clip. A plurality of the pixels of the selected video frames are modified to form modified video frames. The modification to each of the plurality of the pixels is based on the intensity of the pixel, a change in the intensity of the pixel from the corresponding pixel in at least one related video frame, and the intensity of the corresponding pixel. A second video clip is formed that comprises the modified video clips.
