FileBot

Please add support for IMVDB so that I can rename all my music video files with some semblance of sanity.
Its API looks similar to TheTVDB.

You could theoretically build your own and integrated into into FileBot via Plain File Mode custom formatting. See [POC] Custom Format Server for details.

Note that AcoustID can identify music video files based on the acousting fingerprint from the audio stream, exactly the same as with audio-only files. Fairly untested though, might not work well if the music video you have are acoustically different from the audio-only files.
