As its name suggests, this application enables you to capture screen activity and save the results to various video formats. The program comes in handy whenever you need to record radio broadcasts, software tutorials, game walkthroughs, Skype video calls, and many others.
You can opt between various video recording profiles (entire screen, a single window, etc.), configure the sound settings according to your needs, trim the videos before exporting them, and much more. Furthermore, the program gives you access to a wide variety of output formats compatible with dozens of media devices, like mobile phones, Kindle or Apple TV.
You can also set global hotkeys for starting or stopping video recordings, take screenshots, etc.
Another thing I like about this application is the fact that it also lets you take snapshots of your screen.
As a conclusion, I'd say it's definitely worth acquiring this program as it offers all the features you could require to record screen activity on your Mac computer. The application comes with an intuitive interface, lets you choose from various output formats, and provides you with high-quality results.
