Abstract
A technique for frame accurate cropping of MPEG video is presented and discussed. The technique is based on removing temporal dependencies of cropped frames from frames before of after the cropping point while decoding and encoding only the minimum number of frames. Results indicate that the technique presented improves computational efficiency without any effect on the visual quality of the video clip.
