TMVP DERIVATION

A video processing method includes deriving multiple temporal motion vector prediction (TMVP) candidates for a video block in a current picture based on multiple blocks associated with a second block in one or more pictures that are temporally co-located with the current picture, wherein the current picture is excluded from the one or more pictures, and the second block is temporally collocated with the video block, wherein the second block has a same size as the video block, and wherein a relative position of the second block to a top-left corner of a second picture of the one or more pictures is same as that of the video block to a top-left corner of the current picture; adding the multiple TMVP candidates to a motion candidate list associated with the video block; and performing a conversion between the video block and a bitstream.
