Several mouse operations speed up the configuration of several tracks at a time. Click on an attribute and drag the cursor across adjacent tracks to copy the same attribute to those tracks. Hold down Shift while clicking a track's attribute to enable the attribute in the current track and toggle the attribute in all the other tracks. Or you can:

\paragraph{How to do a J-cut or L-cut} A J-cut is a split edit film editing technique in which the audio from a following scene overlaps the picture from the preceding scene, so that the audio portion of the later scene starts playing before its picture as a lead-in to the visual cut. An L-cut is a different split edit film editing technique in which the audio from preceding scene overlaps the picture from the following scene, so that the audio cuts after the picture, and continues playing over the beginning of the next scene (figure~\ref{fig:j-cut}). To do either a J-cut or an L-cut, you first shorten the first or second video a little. Then you block the audio tracks from changing by disarming the appropriate tracks. Finally use \textit{One Edit (roll)} the cutting edge off the videos. Moving to the right creates a J-cut and moving to the left creates an L-cut.
\begin{figure}[htpb]
\paragraph{Cutting/Snapping edits} cuts from an edit handle to the insert point.
There are Edit Panel buttons which normally are used to move to the previous or next edit handle/label.

They look like tags and the letter E on the menu bar and are oriented forward/backward. These same buttons can be used to \textit{cut} from the insert pointer to the previous or next edit/label when the \texttt{ctrl+alt} keys are both pressed when the buttons are used. They \textit{snap} off the media instead of doing the standard re-positioning. This is useful to minimize the number of operations necessary to cut between edits/labels.
Instead of using the edit panel buttons, you can more easily use the following keyboard shortcuts to perform the same functions:
\begin{center}

where \texttt{<path>} is the storage host directory, and \texttt{<ip-addr>} is the network address of the storage host.
Because all of the computers must have the same directory path, create that same directory path with the same uid/gid/permissions on each storage client computer ahead of time.
\item To make this permanent across reboots on the client nodes, add the following line to \texttt{/etc/fstab}:
\begin{lstlisting}[language=bash]
++<<<<<<< HEAD
+ {masternode}:/nfsshare /mnt nfs defaults 0 0
++=======
+ {masternode}:/nfsshare /mnt nfs defaults 0 0
++>>>>>>> einhander
\end{lstlisting}
You can make this permanent on the disk storage host BUT the command lines shown, which were
correct in January 2018 on Fedora, may be different for your operating system or in the future. In
addition if your network is not up, there may be numerous problems. If you make a mistake, your
system may not boot. To make permanent, add the following line to \texttt{/etc/fstab}:
\begin{lstlisting}[language=bash]

You will still have to mount the above manually because of the \textit{noauto} parameter but you won’t
have to remember all of the other necessary parameters. Depending on your expertise level, you can
Later, to remove access to the storage host filesystem:
\begin{lstlisting}[language=bash]

Be aware that you may have to adjust any security or firewalls you have in place. \textit{Most firewalls will require extra rules to allow nfs access}. Many have built-in configurations for this.
number that you want to use in the Port textbox. You can make sure a port number is not already in
use by keying in on the command line:
\begin{lstlisting}[language=bash]
++<<<<<<< HEAD
+ netstat -n -l -4 --protocol inet
++=======
+ $ netstat -n -l -4 --protocol inet

Next, click on the \texttt{Add Nodes}
button and then you will see that host appear in the Nodes list box to the right. The \texttt{X} in the first
\item[Create Workflow] While working on the master computer, it is recommended that you keep all the resources being used on the same shared disk. Load your video/audio piece and do your editing and preparation. Add any desired plugins, such as a Title, to fine-tune your work. You want to make sure your video is ready to be rendered into the final product.
\item[Start the Client Nodes] To start up the client nodes run Cinelerra from the command line on each of the client computers using the following command:
\begin{lstlisting}[language=bash]
++<<<<<<< HEAD
+ /{cinelerra_pathname}/cin -d [port #] ; \#for example /mnt1/bin/cinelerra -d 401
+ \end{lstlisting}
+ This starts cinelerra in command prompt mode so that it listens to the specified port number for commands from the master node for rendering. When you start each of the clients up, you will see some messages scroll by as each client is created on that computer, such as:
+ \begin{lstlisting}[language=bash]
+ RenderFarmClient::main_loop: client started
+ RenderFarmClient::main_loop: Session started from 127.0.0.1
+ \end{lstlisting}
+ As it completes its jobs, you will should see:
+ \begin{lstlisting}[language=bash]
+ RenderFarmClientThread::run: Session finished
+ \end{lstlisting}
+ A quick way to start a sequence of clients is to use:
+ \begin{lstlisting}[language=bash]
+ or n in `seq 1501 1505`; do cin -d $n; done
++=======
+ /{cinelerra_pathname}/cin -d [port #] ; \#for example /mnt1/bin/cinelerra -d 401

\item[Render Using Render Farm] After you have followed the preceding steps, you are ready to use the render farm. Click on File $\rightarrow$ Render\dots which opens the render dialog. The most important point here is to use for \texttt{the Output path / Select a file to render to} a path/file name that is on the shared volume that is also mounted on the clients. Click on \texttt{OK} to render. The cinelerra program divides the timeline into the number of jobs specified by the user. These jobs are then dispatched to the various nodes depending upon the load balance. The first segment will always render on the master node and the other segments will be farmed out to the render nodes. Batch Rendering, as well as BD/DVD rendering, may use the render farm. Each line in the batchbay can enable/disable the render farm. Typically, video can be rendered into many file segments and concatenated, but normally audio is rendered as one monolithic file (not farmed).

\item On each buddy client, create a job for each port:
\begin{lstlisting}[language=bash]
++<<<<<<< HEAD
+ /{cinelerra_pathname}/cin -d port#
++=======
+ /{cinelerra_pathname}/cin -d port#
++>>>>>>> einhander
\end{lstlisting}
\item On the master, bring up the render menu and name the output files, for example \texttt{/tmp/myoutput.mp4}.
\item The client nodes output results will be on their local \texttt{/tmp} filesystems so you will have to again use
in the Nodes listbox. Check the \texttt{X} to disable it which sets \texttt{On} to \texttt{Off}.
\item A red message in the lower left hand corner of the main timeline that reads \textit{Failed to start render
farm} often means that the client cinelerra programs were not started up.
++<<<<<<< HEAD
+ \item A message of \texttt{RenderFarmWatchdog::run 1 killing server thread \#address\#} means that the client did

not respond in time. You can adjust the timer in Settings $\rightarrow$ Preferences, Performance tab.
\item When you get the message \texttt{RenderFarmClient::main\_loop: bind port 400: Address already in use}, use a different port.
\item A message of \texttt{RenderFarmServerThread::open\_client: unknown host abcompany} means that the
hostname of abcompany is not in \texttt{/etc/hosts} so you will have to add it or use the ip address instead.
\item There are numerous error messages associated with file \texttt{open/close/status} or problems with the file
that should be dealt with according to what is printed out.
++<<<<<<< HEAD
+ \item Other illustrative messages may be shown such as: \texttt{RenderFarmClientThread::run: Session finished}.

\paragraph{Warnings}
\item Set the bitrate to $2600000$ ($2600k$ as in ffmpeg example above).
\item Add the following 2 lines after the first line:
\begin{lstlisting}[language=bash]
