What additional controls are available for VBR settings through the API?

When you're using our powerful API to control the VBR settings of your encode, there's a few additional options that you can supply to control the settings. There are a few things to consider:

---> - Bufsize: (Rate control buffer size) You always MUST specify it when setting minrate and/or maxrate. A buffer with that size will be used to calculate current bitrate. 
 
bufsize [optional] - Rate control buffer size (bits).
     Allowed values: N or Nk - where N is any non-zero integer.
     Default: None
 
--> - Minrate and Maxrate : These items limit the bitrate of the encoded video must not drop below or exceed.  
maxrate [optional] - Maximum allowed video bitrate.
     Allowed values: N or Nk - where N is any non-zero integer.
     Default: None
 
minrate [optional] - Minimum allowed video bitrate.
     Allowed values: N or Nk - where N is any non-zero integer.
     Default: None
 
--> - Rc_init_occupancy: The initial rate control buffer occupancy (number of bits which should be loaded into the RC buffer before decoding starts). 
 
rc_init_occupancy [optional] - Initial rate control buffer occupancy (bits).
     Allowed values:  N or Nk - where N is any non-zero integer.
     Default: None
