I haven't been involved in VideoBrainz at all so far. However, my day job is software engineering consulting on multilingual websites ang internationalization of software products. If it be helpful for me to get involved, please let me know how.
I have an aspiration to propose a design and plan to make MusicBrainz fully multilingual. Maybe a multilingual VideoBrainz first would be a good role model for MusicBrainz.
