As of February 1, 2012, you can accept and curate Vimeo, YouTube, and SoundCloud works via your Submittable application. This is great for film and music producers, but also for any traditional publisher wanting to branch out into multimedia.
Here’s an example of the feature being used out in the wild: Hammer to Nail is an independent publisher that reviews and publicizes “American narrative features produced for one million dollars or less.” They recently used Submittable to accept and curate short films from hundreds of filmmakers around the country. The winner of their contest will be promoted on their highly trafficked site and get submission waivers to several major U.S. film festivals.
Thanks! Don’t hesitate with any questions or suggestions.
