The acquisition rate of video equipment makes positive advances, for example, a video with Full-HD resolution can be acquired at 1000 Hz. However, the acquisition process in imaging system is independent from video encoding process. This means that the imaging system does not consider to reduce video encoding rate. This paper proposes a video generation algorithm optimized in terms of video encoding. The proposed method features to use a video signal sampled at high temporal resolution. The video signal sampled at high temporal resolution contains much information of captured scene. Utilizing such information for generating video signal, we can pioneer a way to improve coding efficiency outside the conventional research area of video coding. The proposed method applies a temporal filter that features to select filter coefficients from the candidate set. The selection of filter coefficients for each frame is designed based on dynamic-programming in order to minimize total encoding rate of all generated frames. Experimental results show that the proposed method can reduce encoding rate on average by 2.14 [%] compared to constant mean filter.
