Claim One:
1. A method comprising: storing reference fragments comprising video data associated with a set of tiles of video frames in a sequence of video frames, wherein each tile in the set of tiles represents a subset of partitions for the respective video frame; and performing motion compensation for a current tile of a current video frame based on one or more of the reference fragments; wherein the current tile is co-located with the tiles in the set of tiles; wherein the method further comprises automatically identifying the set of tiles; and wherein automatically identifying the set of tiles comprises: identifying a set of active partitions in each of the video frames, wherein each of the active partitions comprises at least one of a motion vector indicating at least some displacement relative to a partition of a video frame of the reference fragments, and a non-zero residual value vis-à-vis a co-located partition of a video frame of the reference fragments; and for each given one of the video frames, identifying a tile of the given one of the video frames such that the tile includes the identified set of active partitions of the given one of the video frames and partitions of the given one of the video frames that are co-located with active partitions in the identified sets of active partitions of other ones of the video frames.
