1. A method for coding video data, comprising:
constructing a merge motion candidate list for a current video block;
determining a merge candidate from the merge motion candidate list; and
disabling at least one coding tool, when the merge candidate is an asymmetric bi-predictive merge candidate;
wherein different weights indicated by the asymmetric bi-predictive merge candidate are applied to a first prediction block and a second prediction block of the current video block to acquire a final prediction block,
wherein the at least one coding tool further includes a weighted prediction, or a bi-directional optical flow that is used to refine prediction blocks of a bi-prediction, and
wherein the asymmetric bi-predictive merge candidate is a certain type of asymmetric bi-predictive merge candidate.
