Byzanz records your desktop session to an animated GIF. You can record your entire
screen, a single window, or an arbitrary region. byzanz-record allows you to make
recordings from the command line. Graphical users may want to use the panel applet


Application Options:
-a, --audio
Record audio from the default input device. This only works if the output format
supports it and will otherwise cause an error.

-c, --cursor
Record mouse cursor

-d, --duration=SECS
Duration of animation (default: 10 seconds)

-e, --exec=COMMAND
Instead of specifying the duration of the animation, execute the given COMMAND and

more complex ways to stop the recording, like writing scripts that listen on dbus.

After byzanz-record is finished, the recording is written to FILENAME. The format is
determined by the filename extension. The following formats are supported:

byzanz-playback(1) to convert the file.

want to postprocess the file in other applications.

gif Record to an animated GIF image. Use this if you want to record a mostly static
screen with a limited amount of colors, such as using a file manager or an office
application. This is the default and will be used if an unrecognized extension is
