UseBestFormat

Description

This works in connection with the SoundFormat property to allow the SDK to automatically determine the sound format to use on export, based on the format of the various sounds in the movie.

Syntax

[C#/C++]
public Bool UseBestFormat;

[VB.NET]
Public Property UseBestFormat As Boolean

Remarks

If SoundFormat is set to zero, the value of UseBestFormat determines the sound format to be used on export.

If a movie contains more than one sound file, all sounds have to mixed to a single format before being exported. Setting UseBestFormat to True means the highest quality format used by any sound in the movie will be used for the export format. Setting UseBestFormat to False means all sounds are mixed to the lowest quality format used by any sound in the movie.

For example, if a movie has two sounds: one at 44Khz and one at 22Khz:

• SoundFormat = 0 and UseBestFormat = True : all sounds mixed to 44Khz before export

• SoundFormat = 0 and UseBestFormat = False : all sounds mixed to 22Khz before export

• SoundFormat != 0 : all sounds are mixed to whatever format is indicated in SoundFormat.
