Video.ext

Exchange-specific extensions for the video object, available since OpenRTB 2.1. The spec defines nothing inside it, so its contents depend on each exchange's documentation.

Field facts

Path: imp.video.ext
Object: Video
Type: object
Requirement: Optional
Added: OpenRTB 2.1
Spec section: 3.2.7

How it is used

Before 2.6, exchanges carried pod and stitching signals here. Where a 2.6 field now exists, send the standard field and keep the extension copy only for partners that still read it.

Example

Where the field sits in a payload, with everything else left out:

{
  "id": "req-1",
  "imp": [
    {
      "video": {
        "ext": {}
      }
    }
  ]
}

Common mistakes

Leaving pod fields such as a pod ID in imp.video.ext after moving to 2.6, where buyers read Video.podid.
