A student-run poetry festival in the San Lorenzo quarter of Rome will include a videopoetry section, and they’re open for submissions. Langue – Festival della Poesia di San Lorenzo (Facebook page) will be held on May 26. From their call for participants:

Per la categoria Video Poetry, la durata dell’opera dovrà essere massimo di 25 minuti. Qualora il file fosse troppo pesante per una mail, inviaci il tuo lavoro tramite WeTransfer e noi penseremo al resto. Ricordati anche in quel caso di indicare la categoria nell’oggetto della mail.
(For the Video Poetry category, the duration of the work should be a maximum of 25 minutes. If the file is too heavy for an email, send us your work via WeTransfer and we’ll do the rest. Remember also in that case to indicate the category in the subject of the email.)

(Translation via Google.) There’s also a bit in English:

World Wide Poets

If you are not Italian, it doesn’t mean you cannot contribute to our festival. Indeed, you can send us your proposal (an unpublished collection of poems, for example) per mail (festival.langue@gmail.com), indicating if you already have a translation of your work in Italian or at least in English. You can contribute with everything you prefer: readings, video poetry, performances, and so on. The deadline is May 2

I asked the organizer, Giorgio Papitto, if they had preferred languages or file formats. He said they were happy to discuss these matters with submitters “and arrange what suits at the best for the author and for the festival. The language is not a problem, if there are subtitles (either in English or in Italian).”
