20.1.3.6 videoFile (Video from File)
This element specifies the existence of a video file. This element is specified within the non-visual properties of an object. The video shall be attached to an object as this is how it is represented within the document. The actual playing of the video however is done within the timing node list that is specified under the timing element.
[Example: Consider the following picture object that has a video attached to it.
<p:pic>
<p:nvPicPr>
<p:cNvPr id="7" name="Rectangle 6">
<a:hlinkClick r:id="" action="ppaction://media"/>
</p:cNvPr>
<p:cNvPicPr>
<a:picLocks noRot="1"/>
</p:cNvPicPr>
<p:nvPr>
<a:videoFile r:link="rId1"/>
</p:nvPr>
</p:nvPicPr>
…
</p:pic>
In the above example, we see that there is a single videoFile element attached to this picture. This picture is placed within the document just as a normal picture or shape would be. The id of this picture, namely 7 in this case, is used to refer to this videoFile element from within the timing node list. The Linked relationship id is used to retrieve the actual video file for playback purposes. end example]

Attributes |
Description |
|---|---|
contentType (Content Type of Linked Video File) |
Specifies the content type for the external file that is referenced by this element. Content types define a media type, a subtype, and an optional set of parameters, as defined in Part 2. If a rendering application cannot process external content of the content type specified, then the specified content can be ignored. [Note: A list of suggested video types is provided in §15.2.17. end note] If this attribute is omitted, application should attempt to determine the content type by reading the contents of the relationship’s target. The possible values for this attribute are defined by the W3C XML Schema string datatype. |
link (Linked Relationship ID) Namespace: .../officeDocument/2006/relationships |
Specifies the identification information for a linked video file. This attribute is used to specify the location of an object that does not reside within this file. The possible values for this attribute are defined by the ST_RelationshipId simple type (§22.8.2.1). |
[Note: The W3C XML Schema definition of this element’s content model (CT_VideoFile) is located in §A.4.1. end note]
