Property Value

A CaptureInterleavingMode value specifying the interleave mode.

Not all file formats support interleaving. For example, the AVI file format supports interleave mode, while the WMV file format does not. The interleave mode is ignored for those formats that do not support it.

Interleave mode tells the multiplexer (the module that combines audio and video into one file) which method to use to combine data from various streams (video, audio, etc) in the file. Some interleaving modes require more processing and more memory, but generate files more suitable for streaming. Other interleaving modes are faster, and should be used when speed is necessary (for example, during capture).

For a list of possible values, refer to the CaptureInterleavingMode enumeration values.
