The bit rates of the proposed method are reduced with effective coding. In the motion estimation block, the OrTHO-Search is employed with a new RD trade-off in such a way that the Conditional Autoregressive Value at Risk concept modifies the existing RD trade-off measure. The proposed OrTHO-Search-based RD-dependent HEVC renders a good-quality video after compression with half the compression standard when compared with the other existing compression standards. With the concern for quality and video compression, this paper proposes a modified version for HEVC encoding using the Ordered Tree-based Hex-Octagon based block Search and Rate-Distortion trade-off (OrTHO-Search-based RD) for motion estimation and weighted Context-Adaptive Binary Arithmetic Coding (CABAC). HEVC renders effective performance compared to the existing compression standards as the encoding time is minimal. High-Efficiency Video Coding (HEVC) is the standard employed for the subsequent compressing of the video without degrading the quality of the image.
