+Tip: If you have rendered your whole project with \textit{File format}
+set to JPEG and there are no missing numbers in the sequence, you can
+create a video from that sequence outside of \CGG{}.
+For example, if using the default output so that your files are named
+/tmp/brender000000, /tmp/brender000001, ... in a window, you would type:
+
+\begin{lstlisting}[style=sh]
+ffmpeg -f image2 -i /tmp/brender0%5d -c:v copy brender.mov
+\end{lstlisting}
+which would create the video file brender.mov -  be sure to delete
+existing brender files before creating a new sequence to ensure there
+are no missing numerical values in the sequence.
