PREVIEWDURATION Element
[The feature associated with this page, Windows Media Player SDK, is a legacy feature. It has been superseded by MediaPlayer. MediaPlayer has been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer instead of Windows Media Player SDK, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]
The PREVIEWDURATION element defines the length of time a clip plays in preview mode.
<PREVIEWDURATION
VALUE = "hh:mm:ss.fract"
/>

Remarks
This element defines the length of time that a clip plays in preview mode. If this element appears within an ENTRY element or a REF element, it applies to the clip defined by that element. If it appears within the scope of an ASX element, it applies to every clip in the metafile. A PREVIEWDURATION element in a REF element takes precedence over one in an ENTRY element, and either takes precedence over a PREVIEWDURATION element in an ASX element. If no PREVIEWDURATION element is defined for a clip, the default preview time is 10 seconds.
If there is a STARTTIME or STARTMARKER element for the clip, Windows Media Player renders the clip starting at the point defined by one of these elements; otherwise it renders from the beginning of the clip. The clip stops normally if it is shorter than the time defined by the PREVIEWDURATION element.
The DURATION element overrides a PREVIEWDURATION element.
Examples
<PREVIEWDURATION VALUE="0:30.0" />
