Well show you how to record video in Ubuntu using RecordMyDesktop.
RecordMyDesktop is one of the few video capture programs available in Ubuntu.
pop swing open the Ubuntu Software Center (Applications > Ubuntu Software Center).
pop in recordmydesktop in the search box at the top-right.
Highlight the entry marked gtk-recordMyDesktop and click Install.
Thats all you gotta do!
This will install both the core RecordMyDesktop files and the graphical frontend.
To begin recording video, hit Applications > Sound & Video > gtk-recordMyDesktop.
The main screen has a few common options, and a thumbnail of your desktop.
If you want to record sound, ensure that the checkbox beside Sound Quality is checked.
Frame rate can be changed in the Performance tab.
Take care, because video files containing your entire desktop can grow very large.
When you are finished recording your video, snag the stop button in the system tray.
By default, videos will be stored in your home directory, under the name out.ogv.

tap the grey stop button to stop the recording once youre finished.
RecordMyDesktop will create out.ogv in your home directory.
It plays great in Totem.
