In one aspect, a method includes obtaining video data that includes a plurality of blocks, including a first block, where the video data is to be coded in a warp mode or a motion mode. The method further includes identifying two or more warp groups for the first block and determining a respective cost associated with each warp group of the two or more warp groups. The method also includes selecting a warp group from the two or more warp groups based on the respective costs, and encoding, in accordance with the selected warp group, the first block and a syntax element indicating the warp mode or the motion mode without regards to whether a valid motion vector is available.
