Abstract (in Japanese) (See Japanese page) 
(in English) In this paper, we propose a method to control the way of encoding by H.265/HEVC for 8K UHDTV moving pictures. In 8K video, with high resolution, amount of motion is very large. The proposed method estimates the amount of motion by the external process, and sets the search range of motion vectors according to estimated motion amount. At this time, the method expands search ranges per GOP interval to exploit vector interpolation capability by HM. It also selects intra only prediction for movies which have random motion. By this method, we achieve high efficient and low computation encoding.
