Abstract: An apparatus for video encoding includes an image prediction unit configured to generate a prediction image about an input image; and a differential signal generation unit configured to generate a differential signal by subtracting the prediction image from the input image. Further, the apparatus includes a restoration image generation unit configured to generate a first restoration image about the input image using the prediction image; and an in-loop filter unit configured to produce a second restoration image that in-loop filtering has been performed, and after performing rate distortion optimization (RDO) by producing bit amount information necessary for restoring the second restoration image, provide result information of the RDO with the image prediction unit.
