Total garbage. Too limited to be of use to professional editors, too complicated for beginners to use at all. Has dozens of windows, but combined they perform fewer functions than iMovie's one window. Cryptic buttons are used for basic functions. Only semi-stable, semi-hardware compatible. Drag-and-drop support is poor.
If you refuse to pay a dime for video editing software, you get what you pay for. But if you still insist on using freeware only, try www.jahshaka.com instead.
