I'm not sure how much of someone's personality you can determine from a pre-recorded, scripted monologue to the camera. A video can show you how physically attractive some is, slightly better than a photo can (and you could hear if they have a beautiful or annoying voice, unless they're putting on a fake voice) but for personality you need to see how they react in different situations. Even if you can infer things about their personality from the video, that doesn't tell you anything about their likes and dislikes, which can be useful for text-based filtering. Users could mention their likes and dislikes in their videos, but you'd end up having to watch hours of irrelevant footage just to find one match, which isn't a great UX, and is expensive for the site too.
