If like me, you do a lot of screen captures, one of the things you’ll find with the normal ALT-PrntScreen capture method is that you can’t capture context menus. When you try and do a print-screen of an open context menu, it just closes before the screen grab is made.
Enter Pyvnc2swf, which will uses the VNC protocol to grab your desktop and record it to a .flv flash file!
Open your Software Manager and search for Pyvnc2swf and install it. Note that you will need the Python engine installed in your computer to run this Python script. More on that is available HERE
To run the script, just open a Terminal window, and type: vnc2swf
This will open a small user interface, where you can select the type of output file. I recommend Flash. Then it’s just a matter of hitting the Start button, making your screen moves, then hitting the Stop button. Next, save the file to whatever directory you wish.
The resulting flash video file can then be played in your media player of choice, and the frame you wish to show can be grabbed for use.
