Video.minbitrate

The lowest media bitrate the player accepts, in kilobits per second. Buyers use it to check that their VAST creative carries a rendition good enough for the device.

Field facts

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

How it is used

Set it where low-quality renditions look poor, such as large CTV screens, and pair it with Video.maxbitrate to bound the renditions a creative must offer. In 2.0 through 2.2 an absent value meant any bitrate was accepted.

Example

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

{
  "id": "req-1",
  "imp": [
    {
      "video": {
        "minbitrate": 1500
      }
    }
  ]
}

Common mistakes

Sending bits per second, such as 1500000, instead of kilobits per second, such as 1500.
Setting it above Video.maxbitrate, which no rendition can satisfy.
