When the value for this property is YES, the export session can produce higher quality results at the expense of longer export times. Setting this property to YES may also require the export session to write temporary data to disk during the export. To control the location of temporary data, use the property directoryForTemporaryFiles.
The default value is NO. Not all export session configurations can benefit from performing multiple passes over the source media. In these cases, setting this property to YES has no effect.
This property cannot be set after the export has started.
A directory that is suitable for containing temporary files generated during the export process.
