Movie metadata not scanned due to proprietary filename convention

[geohei]

Hi.

Newbie question (after lots of Google searching).
I installed latest JF on my Synology NAS.
I have the following problem regarding metadata scanning.

My naming is as follows (example): Annabelle (TV - 13.11.2015 1925 169 h264 MP2192en MP2192fr).mp4
I am aware that this is not what JF expects for Movies.
Hence, metadata for media file above is obviously not found (Anabelle (2014), tt3322940) by DBd.

I came up with 3 solutions:

1. Manually add IMDb Id as JF/Identity to every movie.
   
2. Add an .nfo file next to the movie (same basename as media filename, but with .nfo extension).
   
3. Appending [imdbid-tt3322940] to the end of the filename (Annabelle [imdbid-tt3322940].mp4).
   

These methods are time-consuming since all must be done manually.

Is there any possible solution I didn't think of to make the DB scanning process somewhat more automated, while keeping the existing filename convention?

Thanks,
