All the documentation about jobfile and audience seems to have disapear. I remember that there is 3 kind of CQ.
vbrQuality is one.
What are the others iwth their description?

* cbr - Constant Bit Rate (CBR) based on avgBitrate only (maxBitrate and quality are ignored)
* vbrBitrate - Vaiable Bit Rate (VBR) based on avgBitrate and maxBitate (quality is ignored)
* vbrQuality - Vaiable Bit Rate (VBR) based on maxBitate and quality (avgBitrate is ignored)
* vbrUnconstrainedQuality - Vaiable Bit Rate (VBR) based on quality only (avgBitrate and maxBitate are ignored)
* vbrUnconstrainedBitrate - Vaiable Bit Rate (VBR) based on maxBitate only (avgBitrate and quality are ignored)
VBR encoding types provide higher quality but are not as well suited to low bit rate streaming situations and can cause network congestion due to spikes in bit rate when streaming. Use CBR for low bandwidth dial-up streaming, VBR constrained types for streaming at higher bit rates where network capacity is available, VBR unconstrained types for download. The quality versus bitrate types allow the output to be targeted towards a specified level of quality or a specified file size.
For lossless audio codec, only the vbrUnconstrainedQuality is allowed. Omitting this property when using lossless audio results in the default value of vbrUnconstrainedQuality being used.
Default:
cbr
Values:
cbr, vbrBitrate, vbrQuality, vbrUnconstrainedQuality, or vbrUnconstrainedBitrate
Type:
string
Example:
<encodingType type="string">vbrUnconstrainedBitrate</encodingType>

Thanks!
Gonna use vbrUnconstrainedQuality :D
