Fields marked with an asterisk (*) are optional.

Field	Type	Details
mimes	array of strings	Content MIME types supported.
minduration	integer	Minimum video ad duration in seconds, for example, `2`
maxduration	integer	Maximum video ad duration in seconds, for example, `15`
linearity*	integer	Indicates if the impression must be linear or nonlinear, for example, `1`. If none is specified, it is assumed all are allowed `1`: Linear/In-stream `2`: Non-Linear/Overlay
placement*	integer	Placement type for the impression, for example `2`. This field can take the following values: `1`: In-stream. Played before, during or after the streaming video content that the consumer has requested (e.g., Pre-roll, Mid-roll, Post-roll). `2`: In-banner. Exists within a web banner that leverages the banner space to deliver a video experience as opposed to another static or rich media format. The format relies on the existence of display ad inventory on the page for its delivery. `3`: In-article. Loads and plays dynamically between paragraphs of editorial content; existing as a standalone branded message. `4`: In-feed. Found in content, social, or product feeds. `5`: Interstitial/Slider/Floating. Covers the entire or a portion of screen area, but is always on screen while displayed (i.e. cannot be scrolled out of view). Note that a full-screen interstitial (e.g., in mobile) can be distinguished from a floating/slider unit by the `imp.instl` field.
plcmt*	integer	Placement type for the impression, for example `2`. This field can take the following values: `1`: In-stream. Pre-roll, mid-roll, and post-roll ads that are played before, during or after the streaming video content that the consumer has requested. Instream video must be set to “sound on” by default at player start, or have explicitly clear user intent to watch the video content. While there may be other content surrounding the player, the video content must be the focus of the user’s visit. It should remain the primary content on the page and the only video player in-view capable of audio when playing. If the player converts to floating/sticky subsequent ad calls should accurately convey the updated player size. `2`: Accompanying Content. Pre-roll, mid-roll, and post-roll ads that are played before, during, or after streaming video content. The video player loads and plays before, between, or after paragraphs of text or graphical content, and starts playing only when it enters the viewport. Accompanying content should only start playback upon entering the viewport. It may convert to a floating/sticky player as it scrolls off the page. `3`: Interstitial. Video ads that are played without video content. During playback, it must be the primary focus of the page and take up the majority of the viewport and cannot be scrolled out of view. This can be in placements like in-app video or slideshows. `4`: No Content/Standalone. Found in content, social, or product feeds. To be considered In-stream, impressions must be set to Sound On by default at start. “Sound On” by default must be signaled within the `playbackmethod` field. Values of `1`, `3`, `4`, and `5` all qualify. All impressions with Default Sound Off (`playbackmethod` value of `2`, `6`, or `null`) must signal an out-stream placement of type of `2`, `3`, or `4`. Additional signals such as Player Size, Placement Type, Linearity, etc. can be used to differentiate between these various out-stream placements.
playbackend*	integer	The event that causes playback to end, for example `2`. This field can take the following values: `1`: On Video Completion or when Terminated by User. `2`: On Leaving Viewport or when Terminated by User. `3`: On Leaving Viewport Continues as a Floating/Slider Unit until Video Completion or when Terminated by User.
protocols	array of integers	Accepted video bid response protocols as defined in OpenRTB, for example `[6,8]`.
pos*	integer	Ad Position as defined in OpenRTB, for example `1`
w*	integer	Width of the player in pixels, for example, `600`
h*	integer	Height of the player in pixels, for example `400`
startdelay*	integer	Indicates the start delay in seconds. If the start delay value is greater than 0, then the position is mid-roll and the value indicates the start delay. `> 0`: Mid-Roll (value indicates start delay in second) `0`: Pre-roll `-1`: Generic mid-roll `-2`: Generic post-roll
maxseq*	integer	Indicates the maximum number of ads that may be served into a “dynamic” video ad pod (where the precise number of ads is not predetermined by the seller).
poddur*	integer	Indicates the total amount of time in seconds that advertisers may fill for a “dynamic” video ad pod, or the dynamic portion of a “hybrid” ad pod. This field is required only for the dynamic portion(s) of video ad pods. This field refers to the length of the entire ad break, whereas `minduration/maxduration/rqddurs` are constraints relating to the slots that make up the pod.
podid*	integer	Unique identifier indicating that an impression opportunity belongs to a video ad pod. If multiple impression opportunities within a bid request share the same `podid`, this indicates that those impression opportunities belong to the same video ad pod.
podseq*	integer	The sequence (position) of the video ad pod within a content stream. The following values are supported: `-1`: Last pod in the content stream `0`: Any pod in the content stream `1`: First pod in the content stream
rqddurs*	array of integers	Precise acceptable durations for video creatives in seconds. This field specifically targets the Live TV use case where non-exact ad durations would result in undesirable ‘dead air’. This field is mutually exclusive with `maxduration`.
slotinpod*	integer	For video ad pods, this value indicates that the seller can guarantee delivery against the indicated slot position in the pod. The following values are supported: `-1`: Last ad in the pod `0`: Any ad in the pod `1`: First ad in the pod `2`: First or last ad in the pod
mincpmpersec*	float	Minimum CPM per second. This is a price floor for the “dynamic” portion of a video ad pod, relative to the duration of bids an advertiser may submit.
battr*	array of integers	Blocked creative attributes as defined in OpenRTB, for example, `[6]`
minbitrate*	integer	Minimum bit rate in Kbps, for example `680`
maxbitrate*	integer	Maximum bit rate in Kbps, for example `990`
api*	array of integers	List of supported API frameworks for this impression as defined in OpenRTB, for example, `[1,2]`. If an API is not explicitly listed, it is assumed not to be supported.
maxextended*	integer	Maximum extended video ad duration if extension is allowed. Blank or `0`, extension is not allowed. `-1`, extension is allowed, and there is no time limit imposed. Greater than `0`, then the value represents the number of seconds of extended play supported beyond the `maxduration` value.
boxingallowed*	integer	Indicates if letter-boxing of 4:3 content into a 16:9 window is allowed: `0` = no `1` = yes.
playbackmethod*	array of integers	Allowed playback methods as defined in the OpenRTB, for example `[1, 2]`. If none are specified, it is assumed all are allowed.
delivery*	array of integers	Supported delivery methods (e.g., streaming, progressive) as defined in OpenRTB. If none specified, assume all are supported, for example, `[1, 2]`
sequence*	integer	If multiple ad impressions are offered in the same bid request, the sequence number will allow for the coordinated delivery of multiple creatives, for example, `2`.
companionad*	object array	Array of Banner objects if companion ads are available. See the Banner Object section for more information.
companiontype*	array of integers	List of allowed companion ad types, for example `[1, 2]` Possible values: `1`: Static Resource `2`: HTML Resource `3`: iframe Resource
skip*	integer	Indicates if the player will allow the video to be skipped, where 0 = no, 1 = yes.
skipmin*	integer	Videos of a total duration greater than this value (seconds) can be skippable; only applicable if the ad is skippable.
skipafter*	integer	Number of seconds a video must play before skipping is enabled; only applicable if the ad is skippable.
