You can track the percentage of a video that your contacts what and view statistics for each video.
How to Setup Video Tracking/Requirements
In order for video tracking to work the page must be editable and the video must be added as an editable video section under editable content. You must use the option where you provide the url for a mp4 or flv file. The other options will not track % watched. The person must already be a contact. This means that if this is a new visitor on a capture page we cannot track their viewing details, as it isn't tracking against the contact. Any video viewed after optin is tracked and stored under the contact.
