Patent attributes
The described implementations facilitate the discovery and presentation of video advertisements in a non-intrusive manner by users of client devices. In one implementation, an informed opt-in preview representative of a video advertisement is generated. The informed opt-in preview is a short video presentation that is formed from frames extracted from the video advertisement that can be presented on a client device to provide a user with an overview of the video advertisement corresponding to that informed opt-in preview. For example, the video advertisement may be a two-minute video advertisement. In comparison, the informed opt-in preview may be as little as three—five seconds in length and simply provide an overview of the video advertisement.
