Video.maxextended

How many extra seconds an ad may run past Video.maxduration, for ads that lengthen when the viewer interacts. Absent or 0 means no extension, -1 means no limit, and a positive value is the extra seconds allowed.

Field facts

Path: imp.video.maxextended
Object: Video
Type: integer
Requirement: Optional
Added: OpenRTB 2.0
Spec section: 3.2.7

How it is used

Extension mostly concerns interactive formats on web players. On CTV and SSAI streams, where breaks have fixed lengths, leave it absent or send 0.

Example

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

{
  "id": "req-1",
  "imp": [
    {
      "video": {
        "maxextended": 0
      }
    }
  ]
}

Common mistakes

Sending the total allowed length, such as 60 for a 30 second maxduration meaning 60 in all, when the value is added on top of maxduration.
