A method, and computer program are provided for adjusting motion estimation video data to remove unwanted data generated by an automatic focusing control (AFC) circuit on the video data recorder. One or more edges or fine points in a sequence of motion compensated images is identified. Difference frames composed of pixel differences are generated from the motion compensated images. The difference frames are examined for evidence of AFC action. In the event AFC action is identified, one or more frames of the sequence of difference frames are filtered to remove the AFC effects. The filtered difference frames are encoded. Identification can be made by detecting a component of oscillation in a comparison of summed pixel differences of a sequence of frames. The difference frames may be filtered by reducing the energy level of one or more of the difference frames or by discarding one or more of the difference frames.
