Summary:A video classification method includes detecting pulldown video frames from within a sequence of video frames, for each video frame within said sequence identifying those frames containing inter-field motion, for each frame containing inter-field motion generating a corresponding top field and bottom field, separately correlating the generated top field with a top field of the video frame immediately previous to the frame containing inter-field motion and with a top field of the video frame immediately subsequent to the frame containing the inter-field motion, separately correlating the generated bottom field with a bottom field of the immediately previous video frame and with a bottom field of the immediately subsequent video frame and determining from the outcome of said correlations if the frame containing inter-field motion is a pulldown frame.
