Another question:

How you handle filename <-> movie set name if movie set name has illegal characters like the ":" in "Mission:Impossible"?

Thank you for hints, but i need a method that will work with any illegal filename character for a proper MSAA integration in Ember Media Manager. That means we need a "Movie Set Artwork Automator" internal solution for this.
We grab the movie set titles from TMDB and manually set name changes can not be the solution.

@trentf: Are you willing to look for a solution together?

Dan, if you go back through this thread you will see this discussed. What MSAA does is strip all non alphanumeric chars on both sides when comparing set names to filenames. So you can either just drop the illegal filename chars when naming the file, or convert them to something nicer on the eye, like ":" -> " - ".

I have indeed already read, but I thought this is just a workaround.
Works great, thank you.
