A method and apparatus for removing from frames of video the effects of automatic gain control (AGC), preferably to prevent the AGC effects from adversely affecting a video codec architecture using motion estimation. Video images are processed by first characterizing the luminance of first and second frames of video data. Any difference in the characterized luminance values is determined. The luminance of the second frame is adjusted based on the determined difference between the luminance of the first frame and the luminance of the second frame, to generate an adjusted second frame. The adjusted second frame is encoded to generate encoded video signals for the second frame.
