perform a conversion between visual media data and a visual media file that includes one or more tracks that store one or more bitstreams of the visual media data according to a format rule;
wherein the visual media file includes a base track that references one or more subpicture tracks,
wherein the format rule specifies an order of non-VCL (video coding layer) NAL (network abstraction layer) units in a sample of the base track in reconstructing a video unit from the sample of the base track and samples in the one or more subpicture tracks, and
wherein the format rule specifies at least some of the non-VCL NAL units in the sample of the base track to be placed in the video unit before or after NAL units in the one or more subpicture track;
