Abstract
An original previously compressed video stream image having a first level of compression including a first level of quantization is decompressed, and a set of original motion vectors for each P source picture and for each B source picture is recovered and saved. The decompressed video stream image is re-compressed re-using the most relevant saved original motion vectors in order to create a re-compressed video stream image having a second level of compression including a second level of quantization. The most relevant motion vectors point out to the camera movement and to the moving objects within the original reference frame.
