Next frame scores are calculated for the video frames. Each frame score is based on at least one image attribute of the image of the video frame, and/or an audio attribute of the audio portion of the video frame. Next, key frames are identified that have a frame score that exceeds a threshold frame score. Finally, a compressed video clip is formed in which the images of non-key frames are removed. A system for implementing the method is also disclosed.Other References
