Clearleft's Silverback is $49.95 software for the Mac that does screen recording augmented with screen capture for guerilla usability testing. Uses the small Apple remote that came with your Macbook for adding a chapter markers on the fly. There's a thirty-day free trial version available. Features include changing location, size, and transparency of inset video, tracking click locations on screen, and more. (You can also turn off the inset video, which lets Silverback double as a simple app for creating screencasts.)
The program lacks the advanced features you might find in spendier products like Morae—there's no built-in video editing (use iMovie) and no stats tracking, but for quick, on-location work, it's definitely worth $49.95.
Ten percent of profits from registered copies goes to the Save the Gorillas campaign. ("Silverback," "Guerilla usability testing," "Save the Gorillas." Get it?)
Update: Hicksdesign, which created the Silverback icon, posted a series of design sketches showing how the icon evolved from basic concept through hand sketches to final design.
