+Rendering takes a section of the timeline, \index{active region} performs all the editing,
effects and compositing, and creates a new media file. You can then
delete all the source assets, play the rendered file, or bring it
back into \CGG{} for more editing. All rendering operations are
path. Since hundreds of thousands of image files are usually
created, ls commands will not work in the background rendering
directory. The browse button for this option normally will not work

\item[File format] The file format for background rendering has to
be a sequence of images. The format of the image sequences
determines the quality and speed of playback. JPEG generally works

+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.
