Screencasting Stars of the Linux World

“Today if you want to showcase your application, your gaming
skills, or even your astonishing new desktop wallpaper collection,
you need a screen recorder (or screencasting tool) to capture
full-motion video and audio of your desktop. You’ll find several
solid options, but which one works best for you depends a lot on
the type of content you need to capture, and what you intend to do
with it.

For starters, the output produced by the tool varies
considerably. Some alternatives give you a wide choice of video and
audio codecs, others just one. But if that one (say, Flash) is the
one you need, producing it directly is much quicker than having to
save an intermediary file are crank it through a video editor. It
also may be important to select just a portion of the screen rather
than your whole display, or to choose a specific frame-rate (high
for games, low for bandwidth-saving demos).”
