VideoNumPasses

Description

Sets the number of passes to be used encoding the video stream in the export process.

Syntax

[C#/C++]
public long VideoNumPasses;

[VB.NET]
Public Property VideoNumPasses As Long

Remarks

This is the number of passes that will be used to encode the video stream. Generally, more passes gives higher quality, but the maximum number of passes available depends on the WMV codec being used.

As a guide, the codecs represented by these identifiers (see compressed media subtypes in the Windows Media Format 9.5 SDK documentation) allow 1 or 2 pass encoding:

WMMEDIASUBTYPE_WMV1 - Windows Media Video 7
WMMEDIASUBTYPE_WMV2 - Windows Media Video 8
WMMEDIASUBTYPE_WMV3 - Windows Media Video 9

And these only allow 1 pass encoding:

WMMEDIASUBTYPE_MSS1 - Windows Media Screen codec version 1
WMMEDIASUBTYPE_MSS2 - Windows Media Video 9 Screen codec

See Exporting to Windows Media Video for more details on use of WMV codecs and formats.
