Three stars because some of the effects are nice however my second time using it, first time was a 1 minute video nothing special, it kept getting stuck after trying to crop clip, then ads kept popping in during sizing etc, I'm testing the app to see if I want to purchase pro for regular use NOPE NOT WONT. This app gets stuck all the time not worth the headache try powerdirector user friendly better features though lacking in effects it's worth the trade off i have 2gb of memory and clean cache
