One solution should be to use find together with a read loop. Inside the look get needed directory and base file names, and in a subshell jump into the directory and execute the command (in following only using pwd and echo for testing purposes).

Another alternative could use pushd/popd commands ...

$ find . -type f -name "*.avi" | \
       while read avi
           do avi_fn=$(basename $avi); avi_dir=$(dirname $avi);
          ( cd $avi_dir && pwd && echo par2create .${avi_fn} $avi_fn );
       done
/tmp/test/e/f
par2create .fifth.avi fifth.avi
/tmp/test/a/b
par2create .first.avi first.avi
/tmp/test/a/b
par2create .second.avi second.avi
/tmp/test/b
par2create .sixth.avi sixth.avi
/tmp/test/d
par2create .third.avi third.avi

Here is the contents of the test dir:
$ find . -type f
./e/f/fifth.avi
./a/b/first.avi
./a/b/second.avi
./b/sixth.avi
./d/third.avi

I did a test with cp:
find config/ -name custom.php -execdir cp '{}' '{}'.pippo \;
files are copied with added suffix.
