摘要： Technologies for inter prediction for a block in a video are provided. In one example, a method includes: parsing a bitstream to obtain a syntax element, where the syntax element includes at least an index of optimal candidate motion information of a current block; determining, based on the syntax element, to construct a first list or a second list for the current block, where the first list is a block-based candidate motion information list, and the second list is a subblock-based candidate motion information list; determining optimal motion information from the first list or the second list based on the index; and predicting the current block based on the optimal motion information. In this method, the block-based candidate motion information list and the subblock-based candidate motion information list are distinguished from each other. This effectively reduces transmission costs of the optimal candidate motion information.

摘要： A mechanism for processing video data is disclosed. A position of a last significant coefficient in a block of residual with a width (W) and a height (H) is determined based on whether W is non-dyadic and based on whether H is non-dyadic. A conversion between a visual media data and a bitstream is performed based on the position of the last significant coefficient in the block.
