Is there a software to which I can tell what is the pattern of the
names of my movies so it can automatically find the metadata about
each movie?
Suggest that you look into using regular expressions via any of the scripting language or hundreds of tools for doing this to change the current file naming pattern to match the one required by EMDB.
For example, Powerful GREP has a free trial that might work for your needs, and likely would not require you to learn much to get the job done. If you're having a hard time figuring out the pattern EMDB needs and the one you're currently using, you likely could get an answer to this problem on Stack Overflow, though you'd need to let people know the version of RegEx (regular expression) you're using and language if you're not using Power GREP.
If it's of use, here's the file naming file naming conventions used by EMDB:
EMDB V2.29 March 18th, 2015
IMDb Search: Improved the IMDb search matching algorithm. EMDB now
fully follows the Kodi/XBMC media file naming conventions
(http://kodi.wiki/view/Naming_video_files/Movies) e.g. "Avatar
(2009).mkv". Multiple files should be extended with "-cd1", "-cd2"
etc. to automatically convert them to playlists.
