If you would like to add advertisement as a source of revenue please contact email@example.com so that we can enable that feature for you.
Besides that you will need an agreement with an ad-supplier.
After you have set up campaigns with your suppliers you can use VAST-tags to add your commercial before, in the middle or at the end of an asset. You can set general advertisement rules e.g. a channel or overrides on specific media files.
If you have already VAST-tags you can add them in the advertisement section of the Magine Pro Console.
