\Option{LambdaModifier$N$ (-LM$N$)} &
%\ShortOption{-LM$N$} &
\Default{1.0} &
Specifies a value that is multiplied with the Lagrange multiplier
$\lambda$, for use in the rate-distortion optimised cost calculation
when encoding temporal layer~$N$.
If LambdaModifierI is specified, then LambdaModifierI will be used for intra pictures.
\par
$N$ may be in the range 0 (inclusive) to 7 (exclusive).
\\

\Option{LambdaModifierI (-LMI)} &
%\ShortOption{-LMI} &
\Default{} &
Specifies one or more of the LambdaModifiers to use intra pictures at each of the temporal layers.
If not present, then the LambdaModifier$N$ settings are used instead. If the list of values
(comma or space separated) does not include enough values for each of the temporal layers,
the last value is repeated as required.
\\

\Option{IQPFactor (-IQF)} &
%\ShortOption{-IQF} &
\Default{-1} &
Specifies the QP factor to be used for intra pictures during the lambda computation.
(The values specified in the GOP structure are only used for inter pictures).
If negative (default), the following equation is used to derive the value:
\par
$IQP_{factor}=0.57*(1.0-Max(0.5, Min(0.0, 0.05*s)))$
\par
where $s = Int(isField ? (GS-1)/2 : GS-1)$ and
