I was once asked: what is the absolute minimal checklist I should use to validate a business video?
Here's my answer:
That's it. If you hit on those two boxes, you just cleared the way to making sure that your viewers will trust you. That will work even if the video is not too polished, obviously under-funded or not quite as good as you wish it was. Trust is everything.
Don't believe me? This little article on TechBizVideo makes the same point, from a slightly different angle.
