Screenflick is good software. It captures full video with sound from your Mac desktop, full screen or a portion. I’m using it to record games I play. Could have all sorts of applications.
There’s a variety of screen capture options on the Mac from the free recorder included in Quicktime to the market leader ScreenFlow for $99. Screenflick’s only $29 and is very good at capture, including keystrokes, mouse events, and audio via Soundflower. I also appreciate its ability to downsample the raw video when recording. It also has an impressive variety of export options.
The big drawback is that Screenflick has no editor, not even a simple interface for cropping out sections of video. My theory is that’s what iMovie is for. But folks I know who produce a lot of screencasts appreciate that ScreenFlow is an integrated solution.
