@item -vn (@emph{output})

@item -bt @var{tolerance}
|

Set video bitrate tolerance (in bits, default 4000k).
|
||||
Has a minimum value of: (target_bitrate/target_framerate).
|
||||
In 1-pass mode, bitrate tolerance specifies how far ratecontrol is
|
||||
willing to deviate from the target average bitrate value. This is
|
||||
not related to min/max bitrate. Lowering tolerance too much has
|
||||
an adverse effect on quality.
|

@item -maxrate @var{bitrate}
|
||||
Set max video bitrate (in bit/s).
|

Requires -bufsize to be set.

Set min video bitrate (in bit/s).

These four options (lmin, lmax, mblmin, mblmax) use 'lambda' units,
|
||||
but you may use the QP2LAMBDA constant to easily convert from 'q' units:
