\CGG{}’s default setup is in the file \texttt{\$CIN\_DAT/expan\-ders.txt} but if the user wants their own specific setup and if the file in \texttt{\$HOME/.\\bcast5/expanders.txt} exists, it will take precedence.
If there are recommendations for other relevant categories, they can be added. The subtree structure is applicable to any of the \textit{Video Effects/Transitions} or \textit{Audio Effects/Transitions}. You can not sort once an expansion is in effect (figure~\ref{fig:expander}).
-The \texttt{expanders.txt} file has very specific requirements. The most specific is that there are no blanks -- you must use tabs only. A \# (pound sign) can be used in column 1 to indicate a comment. Here is a short example:

+NOTE: The capability to put the expanders.txt file in \texttt{./bcast5} (see \nameref{sec:bcast5}) allows for customizations such as grouping favorite plugins in one section so that they can be recalled more quickly. For this purpose, the \textit{Favorites} section has been included at the top of Video Effects, the contents can be changed as desired. Once your modified file is saved to hard disk as \$HOME/.bcast5/expanders.txt it will remain in use on every update as long as you do not delete it or remove the .bcast subdirectory.
+For users running \CGG{} using the AppImage, to make an initial copy of expanders.txt, execute the
+following lines on /tmp:
+\begin{lstlisting}[numbers=none]
+ git clone --depth 1 "git://git.cinelerra-gg.org/goodguy/cinelerra.git" cinelerra5
+ cp /tmp/cinelerra5/cinelerra-5.1/expanders.txt $HOME/.bcast5/expanders.txt

\subsection{Speed-up of Ffmpeg plugin usage with OPTS files}%
\label{sub:speedup_ffmpeg_plugin_opts}
\index{plugins!speed-up via options}
\index{delay audio}
In the Delay Audio effect you can specify the number of seconds you want to delay the video track.
+An alternative ffmpeg plugin is F\_adelay.
\subsection{DeNoise}%
\label{sub:denoise}
\item[Damp:] echo envelope decay factor used to smooth the cepstrum/correlation data.
\item[Peaks:] number of maximal envelope values used in the echo gain calculation.
\item[Cutoff Hz:] low frequency cutoff value to prevent beat frequency (\textit{heterodyne}) echo canceling.
- \item[Mode:] \textit{MAN}, \textit{Off}, or \textit{On}. When Off is selected, the plugin is not active. When MAN is used, the only one peak is used for the echo gain envelope. It is set by pressing mouse button $1$ in the ceptstrum graphical output. The Gain and Offset are updated as the pointer drag operation resets the indicated gain and offset values. When On is selected, the echo gain envelope is automatically calculated by cepstrum and auto-correlation of the input audio in the last window size audio samples.

It is set by pressing mouse button $1$ (LMB) in the ceptstrum graphical output. The Gain and Offset are updated as the pointer drag operation resets the indicated gain and offset values. When On is selected, the echo gain envelope is automatically calculated by cepstrum and auto-correlation of the input audio in the last window size audio samples.
\item[Windows size:] parameter can be set to \textit{Default}, $1024$, $2048$, \dots \textit{doubled values\dots} up to $262144$.
\item[Amplitude:] the cepstrum value at the drag point during manual envelope selection.
\item[Gain:] echo gain setting determined by manual selection.

+git clone --depth 1 "git://git.cinelerra-gg.org/goodguy/cinelerra.git" cinelerra5
