[FFmpeg-user] hoping for help developing a process

so i've recently received a few corrupted videos that i'm trying to help
some friends recover.
the videos are encoded in ProRes 422 and encapsulated in .mov
these videos have anywhere from a few to many damaged frames. some
damaged frames simply have a few small colored blocks, and others have
huge horizontal tears. when played in VLC, it shows the problematic
frames as duplicates of the last good frame, which is why i turned to
ffmpeg in the hope that it might allow me to script a conversion that
would allow them to be watchable, even if not perfectly.
i can't seem to figure out which options under ffmpeg would allow me to
replicate that functionality of vlc. it would also be wonderful if there
were a way to log all of the places where there were problems, as i do
have access to adobe premier and could then use that to 'morph cut' and
give a better final result. better than that would be a filter that
would allow me to morph from last good frame to next good frame over an
equivalent count of the damaged frames.
many thanks to the experts out there for your help in advance
