  If you want to modify exclusions, you have to edit the code.

  I would put

    *.mp[34]

  in a separate config file.  I usually name those after the script to
  make them easier to find:

    #!/usr/bin/env bash
    export PATH=/usr/local/bin:/bin:/usr/bin
    tag=${0##*/}
    ...

    excfile="/usr/local/etc/${tag}-exclude"
    test -s "$excfile" || { echo die screaming; exit 1; }
    ...

    rsync -anuv --exclude-from="$excfile" "$source" "$destination"
