Using Gnome's embedded screencast tool -------------------------------------------------

Gnome3 has already a screen recording functionality. Pressing Alt+Ctrl+Shift+R
recording will start. There should be a red icon on the message tray in the right-bottom
corner of your screen. If the message tray is hidden, Super+M will activate it.
Pressing the red icon will stop the recording. The video is saved in the Video directory on
your home directory on webm format.

-- Aumentando o tempo da captura embutida no G3

Using dconf editor:

    Type dconf-editor in a terminal;
    Go to org->gnome->settings-daemon->plugins->media-keys and set the value of the property
max-screencast-length by double-clicking on the actual value (30)

Using the gsettings command:

Open a terminal and type:

gsettings set org.gnome.settings-daemon.plugins.media-keys max-screencast-length 45

This command set the value of screen maximum length screencast to 45 seconds.
