Videos can be a useful and innovative way of getting your message across, but they must be appropriate for the target audience. They are a relatively expensive way of reaching an audience and rely on specific opportunities to view them. If you do decide to produce one you should invest the time and money to do it properly and avoid producing the typical 'dull corporate video'. Bear in mind that high profile audiences can sometimes find them patronising, preferring to hear key information face-to-face from a peer than from a 'talking head' on a screen.
