xGrab lets you quickly record all activity on your screen in seconds.
This simple little application monitors all your screen actions and automatically compresses your movie thanks to double buffering. It's perfect if you just want to quickly record what's going on on your desktop, like playing back how an error occurs or doing a quick screencast. Recordings are smooth and of good quality.
The settings are a little limited but still let you configure a number of things. The application only offers two ouput resolutions: full screen and fixed. However for the second choice you'll be able to adjust height and width yourself. We were also positively surprised by the wide selection of codecs you can choose from. You'll also be able to set frame rate and select from six different quality levels.
Although its settings are somewhat limited, xGRab is a good application to record your screen in a snap. It also offers a good range of codecs.
