Don't be discouraged from selling- but don't sell anything you can't afford to lose- at least until you build up your feedback and selling experience. Start with lower value items or items you won't miss if something happens. There's a learning curve with this site.
eBay won't look at videos. Insurance is for the seller's protection in the event of a lost or damaged in transit parcel. A buyer's feedback means nothing since sellers are only allowed to leave positive feedback. A buyer's feedback left for others may or may not give you clues about the buyer's behavior.
You need to learn about eBay's seller performance standards- it's not as easy as cancelling a sale if you want to keep your selling account active. Like I said- learning curve. Get to know the eBay policies and the money back guarantee.
