Creating screencasts in GNOME

On omg! ubuntu! I have learned a nice trick! In GNOME 3 there is a builtin tool to record screencasts. It records the whole desktop and without sound, so if You need something fancier, You should look somewhere else.

To start recording, You should press

Ctrl + Alt + Shift + R

Then, in top right corner red dot will appear:

Normal desktop

Recording desktop

 
To end recording, use the same key combination. By default, GNOME stops recording after 30 seconds. To check maximal movie length, use the following command:

gsettings get org.gnome.settings-daemon.plugins.media-keys max-screencast-length

If You want to record longer movies, use command

gsettings set org.gnome.settings-daemon.plugins.media-keys max-screencast-length <length in seconds>
