I'm sorry, but Captivate is RUBBISH for doing video demos. If I had a pound for everytime it has crashed or corrupted a project I could retire. I've just lost over an hour's work (again) because I committed the cardinal sin of adding a highlighting box and now the document just freezes the program completely. At other times, it loses the video, or relabels it as a highliting box, or adds rows UNDERNEATH it on the timeline, or suddenly won't allow any editing on anything that inhabits the row immediately above the video. Seriously guys - I'm a huge fan of other Adobe products, but this is worse than the most flaky freeware I've ever had the misfortune to use. Not fit for purpose is an understatement.
