Video encoding methods, video encoding equipment, and bit stream storage methods

Abstract

The invention relates to a method of video encoding, a video encoding device, and a method of storing bit streams. The method may include determining, by means of a video processor, the initial motion vector for the video block of the video frame from the video chip. This method may also include, by the video processor, the process of fine-tuning motion based on two-dimensional matching at the volume level to repeatedly update the initial motion vector until a finely tuned motion vector is obtained for the video volume. This method may also include: The fine-tuning of the video processor and motion vector for each sub-block within the video block uses the fine-tuned motion vector of the video block as the starting point for the motion vector of the sub-block. Fine-tuning the motion vector at the sub-block level applies the affine motion model of the video block.
