1. A method of processing video data, comprising:
determining, for a conversion between a current video block of a video and a bitstream of the video, that a first technique is applied for the current video block; and
performing the conversion by applying the first technique and by excluding applying a second technique,
wherein one of the first and the second techniques corresponds to an intra-block copy (IBC) technique, and the other of the first and the second techniques corresponds to a Decoder-side Motion Vector Refinement (DMVR) technique,
wherein in response to the DMVR technique being applied during the conversion, a refined motion vector for the current video block is derived based on a cost calculation between prediction samples of the current video block in different reference pictures of the current video block, and
wherein the method further comprises, in response to at least one of reference pictures of the current video block being a current picture which includes the current video block, excluding applying the DMVR technique for the current video block during the conversion.
