How do you handle the video when you launch?

When you’re getting ready to launch, do you make the video yourself, pay someone to do it, or end up skipping it?

I’m launching Teasr tomorrow which turns your product website into a short launch video using your fonts, colours and images, with music composed for it.

I’d be interested to hear what you’ve tried and where you got stuck - whether that was the editing, the cost, or figuring out what to show.
