Dont bother with this one yet.
ALL this app does is crop and combine video clips and allows you to add a title and music. Thats it. No filters. You are supposed to be able to save the resulting video to your camera roll but it doesnt work. Better ones out there. Why Apple is promoting this is beside me! They must be getting paid to promote it or something.
