You've posted several times in this thread so far complaining about the ads, do you have a source? There aren't any video ads right now nor did they specify _anything_ about how they might work. The only thing they _did_ say, was that user content won't be used in ads.
"Based on how they were being positioned for the summer launch, video ads will appear to targeted users in their news feeds up to three times on the day they’re slotted and will begin silently playing when a user scrolls over them, according to source who heard Facebook’s pitch.
Audio won’t be activated unless a user clicks on the 15-second ad, at which point it will restart and spread over the right- and left-hand rails of the page."
