Pinnacle Video Spin
Full user review
Seems to support 3gp (cell phone format) videos, where other free video editing apps don't.
Every time I try to finalize a video, it force crashes the whole thing.
I couldn't find a free 3gp editor (all the ones I could find are converters that turn your DVDs into 3gp format), so if ithis works it would be perfect. But I went with a paid software program and am uninstalling this.
