Screencasts?video tutorials that focus on a captured computer screen accompanied by narration?are an increasingly popular instructional medium. They show rather than simply tell, making them a solid aid for illustrating what can be confusing concepts when confined to print.
Producing a polished screencast, however, requires more than firing up any old screen-capture utility, pressing Record, and nattering away into your MacBook?s microphone. You want a tool that captures action at acceptable-and-better frame rates, offers flexible export options, doesn?t slow you down by taking dozens of minutes to render your work, has�enough flexibility to capture not only your Mac?s screen but also an attached camera, and provides an easy way to focus on the portion of the screen you?d like to draw attention to. If that tool also includes a good set of editing and annotation tools, you?ve really got something.
And ?something,? in this best sense of the word, pretty well describes Telestream?s $99 ScreenFlow 4.
