Enumeration Type Documentation

enum Enum

BitrateMode::Enum.

Enumerator:
Unknown 

The bitrate mode is not specified or unknown.

CBR 

Constant bitrate.

For uncompressed audio/video with constant bitrate the quality is also constant. For compressed audio/video with constant bitrate the quality may be constant or variable.

VBR 

Variable bitrate - quality oriented.

Constant quality (more or less).

ABR 

Average bitrate.

Guarantees a predictable audio/video size similar to CBR. The bitrate changes to achieve the best quality within the available bitrate capacity.
