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
$GS$ is the gop size.
\\

\Option{ECU} &
%\ShortOption{\None} &
\Default{false} &
Enables or disables the use of early CU determination.  When enabled, skipped CUs will not be split further.
\\

\Option{ESD} &
%\ShortOption{\None} &
\Default{false} &
Enables or disables the use of early skip detection.  When enabled, the skip mode will be tested before any other.
\\

\Option{FEN} &
%\ShortOption{\None} &
\Default{0} &
Controls the use of different fast encoder coding tools.  The following
tools are supported in different combinations:
\par
\begin{tabular}{cp{0.45\textwidth}}
 a & In the SAD computation for blocks having size larger than 8, only
     the lines of even rows in the block are considered. \\
 b & The number of iterations used in the bi-directional motion vector
     refinement in the motion estimation process is reduced from 4 to 1. \\
\end{tabular}
Depending on the value of the parameter, the following combinations are
supported:
\par
\begin{tabular}{cp{0.45\textwidth}}
 0 & Disable all modes \\
 1 & Use both a \& b tools\\
 2 & Use only tool b \\
 3 & Use only tool a \\
\end{tabular}
\\

\Option{FDM} &
%\ShortOption{\None} &
\Default{true} &
Enables or disables the use of fast encoder decisions for 2Nx2N merge
mode.  When enabled, the RD cost for the merge mode of the current
candidate is not evaluated if the merge skip mode was the best merge
mode for one of the previous candidates.
\\

\Option{SBTFast64WidthTh} &
%\ShortOption{\None} &
\Default{1920} &
Picture width threshold for testing size-64 SBT in RDO (now for HD and above sequences).
\\

\Option{RDpenalty} &
%\ShortOption{\None} &
\Default{0} &
RD-penalty for 32x32 TU for intra in non-intra slices.
Enabling this parameter can reduce the visibility of CU boundaries in the coded picture.
\par
\begin{tabular}{cp{0.45\textwidth}}
 0 & No RD-penalty \\
 1 & RD-penalty \\
 2 & Maximum RD-penalty (no 32x32 TU)\\
\end{tabular}
\\

\Option{FastLocalDualTreeMode} &
%\ShortOption{\None} &
\Default{0} &
Controls intra coding speedup introducted with local dual tree mode. 
\par
\begin{tabular}{cp{0.45\textwidth}}
 0 & Disabled\\
 1 & Stop testing intra modes in inter slices, if best cost is more that 1.5 times inter cost.\\
 2 & Test only one intra mode in inter slices\\
