Description of FBE200 VBR Settings


Is there a description of the VBR settings for the FBE200?

When in VBR mode is the bitrate selected used as the average with the Min qp and Max qp settings used to adjust the deviation from the selected bitrate?
Is the encoder using standard x264 quality adjustments?
Does a lower number mean better quality?
What is the default Q? I’ve read that it is 26, is this accurate for the FBE200?
