Video content items are automatically, or with some user input, created for objects based on assets associated with the objects. Where the object is an application, the assets may include images of the application, footage of a user using the application, and textual descriptions or reviews of the application. The assets are arranged using templates that specify audio content to use during the video content item, as well as animations to use during the video content item. A generated video content item can be distributed with the object, or may be used to promote the object.
