The video idea gets floated a lot amongst eBay sellers, but scuttfarkas has it correct: it's pointless. I can show myself wrapping up my best pearl necklace, putting it in a box, and sticking a label on it, but there's nothing to say that as soon as the camera's off I don't unpack it again, put in a string of white beads, and ship that to the customer.
Don't be scared of eBay. It's like selling anywhere else - you can protect yourself to a very significant amount using various eBay tools, obeying the rules, shipping with insurance if you're worried about the dollar amount or you get a "feeling" about the buyer, etc. You'll still occasionally get ripped off, but it'll be a very, very minor part of your business and EVERY business owner gets stuff stolen occasionally, regardless of where or how you sell.
