Abstract: A frame rate converter device and method for interpolation during frame rate conversion are disclosed. The method includes, receiving input frames containing film content and video content. The film content exhibits a 3:2 pull-down cadence while video content that does not exhibit such cadence. Consecutive frames Cn and Cn+1 are interpolated to form Fn using the frame rate converter. The frame rate converter further selects as an output frame, either current or previous ones of interpolated frames or input frames. The selection is made so as to reduce both film judder and video judder. The invention is suitable for use on video input frames at 60 frames per second (fps) derived from a 24 fps cinema using 3:2 pull-down, and also blended with 60 Hz overlay video such as subtitle text. The invention can be used to obtain a good overall reduction in both overlay video judder and film judder.
