Is there any adjustment for substituting missing frames in one direction with additional frames (if available) in the other direction? That would nicely help shot changes and other frames near a change.

Just reverse the video, apply the SuperResolution filter, reverse again, and merge the two results (normal, and reversed-reversed), or, if you are really patient, replace the eventual frames before/after the scene change, accordingly to which is the best - but you must be totally crazy to do this by hand! (^^,) ...but if you can find an automated way, though...
