For now, there may be three places in our code where that happens. However, in the future, we may add more - or third-party apps may be developed which programmatically create Video instances.

More to the point, it makes *sense* to handle this with a signal. There is no reason for such video-specific code to be handled in Feed or SavedSearch methods.
