Directed interpolation and data post-processing

A post-processing device, comprising:

• a decoder for decoding a video bitstream, the decoder configured to:
• receive the video bitstream comprising at least one region comprising two images;
• receive metadata from the video bitstream indicating a width and height of an image of the two images;
• receive first recommended information in the video bitstream identifying a first post-decoding process to be applied to the at least one region, the first post-decoding process being a spatial process;
• receive second recommended information in the video bitstream identifying a second post-decoding process to be applied to the at least one region;
• disregard the first recommended information without applying the first post-decoding process to the at least one region;
• and
• apply the second post-decoding process identified by the second recommended information to the at least one region,
• wherein the video bitstream further comprises a second region different from the at least one region, and
• wherein the second post-decoding process is not applied to the second region.
