4:2:0 format is mainly used for the video coding, however, the picture quality in high saturation color is reduced, because of the gamma correction and the sub-sampling, especially in HDR system. For this, we have the frame sequential video which retains the perfect spatial resolution. However, the motion estimation between different colors is not easy in high saturation color. To solve this problem and to achieve perceptually rational coding, we proposed the pastel colored method which add white component to each frame. In this report, we discuss the inter-frame interpolation for the lacked color and the motion estimation. And, we propose the adaptive method with bi-directional interpolation in the time axis. Also, the inter-color prediction at an intra-frame is realized by the spatial filtering for the difference between interpolated plane and existed plane. Finally, it is recognized that the proposed methods is effective for the occlusion area by the experiments.
