Abstract
In one embodiment, a 3:2 pull-down detection component of a video encoder uses motion vectors to determine whether a repeated field exists in a video sequence. The 3:2 pull-down detection component uses field motion vectors determined by a motion estimator and compares the field motion vectors to a threshold to determine whether a repeated field exists. If a repeated field exists, a video encoder can then eliminate the repeated field.
