## Description

This element points to an external entity containing video data.

### Processing expectations

May be formatted inline or as a displayed block, depending on context. Rendering a video is usually accomplished by reserving a rectangular area on the display and “running” the video in that frame.

There are two ways to provide content for `VideoData`: `EntityRef` or `FileRef`. It is best to use only one of these methods. However, if multiple sources are provided, `EntityRef` will be used in favor of `FileRef`.

### Parents

These elements contain videodata: `videoobject`.

## Attributes

align

  `Align` specifies the horizontal alignment of the image data on the page or within the element that frames it.

depth

  `Depth` specifies the desired depth (vertical distance, at least in horizontal writing systems) of the video data.

entityref

  `EntityRef` identifies the general entity which points to the content of the video data.

fileref

  `FileRef` specifies the name of the file which contains the content of the video data.

format

  `Format` identifies the format of the video data. The `Format` must be a defined notation.

scale

  `Scale` specifies integer representing a percentage scaling factor (retaining the relative dimensions of the original video frame). If unspecified, the value 100 (100%) is assumed.

scalefit

  If `ScaleFit` has the value 1 (true), then the video frame is to be scaled (uniformly) to the specified width or depth. The default value of 0 (false) indicates that the image will not be scaled to fit (although it may still be scaled by the `Scale` attribute).

srccredit

  `SrcCredit` contains details about the source of the video data.

width

  `Width` indicates the width of the graphic.
