I run a stock photo website which is used by thousands of web designers and print designers. Before downloading content the user must watch a 30 second video advert. You are paying for 1000 full views. You can sign up to advertise at stockola.com and see for yourself how adverts work by downloading an image. Happy to answer any questions. Remember this advertising is very targeted and used mostly by designers so if your product could benefit from being shown to these people why not give it a try. Users can click the video and be taken to a URL of your choice. Thanks!
