    • Video Pause
    • Video Maximized

DV, IAS, MOAT trackers

Double Verify, IAS and MOAT wrapping should be done in the DSP or directly with the respective vendors and not via Nova platform. 

These are verification vendors, not standard tracker URLs. VAST does not support this out of the box, each of those vendors will have their own way to wrap/apply their technology to VAST ads. Depending on the verification vendor, the way they wrap the tag may have implications with its compatibility - for example, if the verification vendor uses VPAID extensions to provide tracking or extra analytics, that will only work in VPAID-compatible inventory.
