After few days, you can select the fixed amount to advertise the video of any product that you are interested.Because they are adding this feature soon. But facebook do not allow you to publish any porn ads on them. You can make any ads request from the promotion page of facebook with some easy steps. The ads will show at every time at facebook with sound to attract the people who active on web. The videos will start autometically. But you can not do anything while the video is playing. So that this system still in review. If it granteed then everybody can access this system.
