1. A system comprising:
a video decoder to receive a video input stream having a plurality of first motion vectors, the video decoder to provide decoded video and the plurality of first motion vectors associated with the video input stream;
a first memory coupled to the video decoder to store the plurality of first motion vectors;
a scaler coupled to receive the decoded video and to provide a scaled video; and
an encoder coupled to the scaler and the first memory to provide a compressed representation of the scaled video using the first motion vectors saved in the first memory, the encoder having a vector generation portion that provides second motion vectors based on the plurality of first motion vectors saved in the first memory, the second motion vectors including a specific motion vector based on a most frequently occurring motion vector selected from the plurality of first motion vectors by a tie breaking function using a random method or a predetermined selection pattern.
