1. A method of processing video data, comprising:
determining, for a first conversion between a first video block of a first picture of a video and a bitstream of the video, that an affine motion mode is applied for the first video block;
constructing, for the first video block, a motion candidate list comprising at least one constructed motion candidate that is generated based on a temporal motion information; and
deriving prediction samples based on the motion candidate list and performing the first conversion,
wherein a position from which the temporal motion information for generating the at least one constructed motion candidate is derived is constrained to be within a first subpicture of the first picture,
wherein the temporal motion information is unavailable in response to the position being not located within the first subpicture, and wherein the position is at a bottom-right corner of the first video block, and
wherein a subpicture coding mode in which a video picture is divided into multiple subpictures is enabled for the first picture.
