This app will crash if your movie has a lot of short clips, so its not much good for a music video, for example. As other reviews have noted, once it crashes, your project is toast. Too bad, because the filters look terrific. The "fun facts" it gives you while rendering: *great* idea, terrible execution: "facts" are often incomplete or wrong, and sources are not provided. Wish I could give it more stars, but it just doesnt quite work the way it ought to.
