If the RedDrive dropped frames (giving rise to "green" frames in the R3Ds) then there's not much one can do besides regenerating isolated frames if they can't be re-shot.
That's one of many reasons we go with our cameras - we can keep an eye on the drop frames counter and a host of other variables to make sure our clients don't get surprised by this issue in post.
I hope you got the answers you were looking for Hiroki, sorry I couldn't quite translate your post correctly, my Japanese staff member is unfortunately in the U.S. right now and Google Translate, while ok, still has major issues with translating Japanese to readable English (though it's getting better).
Cheers all,
Paul
