Looks neat, but is there that much difference between silverback or just recording people using screenflow? I get the idea of the chapter marking, and I guess it probably helps if you're trying to track 10+ subjects at a time...
I haven't used Screenflow before but it looks like Silverback is a little cheaper, simpler and designed specifically for user testing.
Have you (or anyone) used Screenflow for user testing?
I've not used it "specifically" for testing, but have let people use a site and record via screenflow. I wasn't being terribly scientific about it at the time tho. :)
Awesome - were the results interesting?
Sorry I didn't reply before. Not as interesting as I'd hoped - I either needed to give more direction, or need to use a bigger group next time.
