Dear Ethan,
I am confused with the terminology MBR used by you, what it means as per standard ?
As such there is
CBR - Constant Bit Rate( Encoder must meet user set target bitrate )
VBR - Variable Bit Rate ( There is no cap on Maximum bitrate to be achieved by encoder, video image quality is the encoder's priority irrespective of result bitrate)
CVBR - Constrained VBR ( Extended VBR standard where there is cap on Maximum Bit Rate, to achieve quality under complex scene encoder can not exceed the Maximum Bit Rate cap).
Do you mean the term MBR is CVBR as per standard ?
