I tried this while it was on sale at MacZOT and though I had a few problems, the developer responded to my email and I assumed the problems would be resolved. After purchasing the app I haven't been able to get a response. One bug was fixed but has been replaced by others. Currently I can't even add an .avi file without an AppleScript error popping up. Assuming this is a solo developer, I can understand being *slow* to respond to support requests, but not failing to respond at all. The *promised* features are good and overall the app seems like it would be easy to use if it worked, hence the 4 rating for those. But the app has failed every time I've tried to use it (and I'm not doing anything advanced with it), which means a 1 for stability ad value. It might be cheap software, but any money spent on this is a waste. If something changes I would be glad to post a new review.
