I think that I forgot to tell you a few things earlier:
Please find out what top-posting means and avoid it here.

If you want to use mcdeint, do not combine it with "-r", the
combination makes no sense and therefore will get very
little support.

In any case, try to simplify your command line before asking
for help, please remove "concat=n=1", it makes no sense either.
This includes the removal of the forced (original) resolution
and aspect ratio.

Once you reproduced with current FFmpeg and a simplified
command line, please post the command line including
complete, uncut console output again.
