Enumerator
ABR	Average Bitrate. Ensures that the output stream achieves a predictable long-term average bitrate.
ConstantQuant	Constant Quantization. Encodes the video to a constant quantizer. The encoder uses the specified target quantizer, not a target bitrate. The quantizer is a measure for the amount of data loss: a higher quantizer means that more data will be lost, which results in a better compression, but also delivers worse visual quality. This method could be used when a certain level of quality is required and the final bitrate is not a concern. The bitrate is unpredictable in this mode.
