20.1.3.4 quickTimeFile (QuickTime from File)
This element specifies the existence of a QuickTime file, as defined in the 2007-09-04 version of the QuickTime File Format Specification: http://developer.apple.com/documentation/QuickTime/QTFF/qtff.pdf. [Note: For more information on the QuickTime format: http://developer.apple.com/reference/QuickTime/. end note]. This element is specified within the non-visual properties of an object. The QuickTime file shall be attached to an object as this is how it is represented within the document. The actual playing of the QuickTime however is done within the timing node list that is specified under the timing element.
[Example: Consider the following picture object that has a QuickTime file 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:quickTimeFile r:link="rId1"/>
</p:nvPr>
</p:nvPicPr>
…
</p:pic>
In the above example, we see that there is a single quickTimeFile 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 quickTimeFile element from within the timing node list. The Linked relationship id is used to retrieve the actual video file for playback purposes. end example]
