Describes how to deliver VAST documents to your video player

You create a VAST video advertisement, e.g. a pre-roll, in Adnuntius by creating a Line Item with a Creative that uses a Video Layout.

Note: if there are no existing Video Layouts, then you will first need to generate one. You create a new layout, select VAST as the Layout Type, and then an appropriate render template will be automatically generated for you.

Make sure to target the creative or line item to the correct ad unit that can handle the vast format. In order to render the information in a correct way, you will have to use HTTP delivery that looks like this:

The important thing above is the &tt=vast2 at the end, since it tells the delivery how it will render the information. Adnuntius supports VAST 2.0, 3.0, 4.0, 4.1 and 4.2. To deliver a VAST 3.0, 4.0, 4,1 or 4.3 ad, you must use either a &tt=vast3, &tt=vast4, &tt=vast4-1 or &tt=vast4-2 parameter instead. The example above is the simplest version of HTTP delivery for ads. More parameters about user and targeting can be added as well.
