The only thing I saw you could do than SAVE was the effects, which, BTW, are just changing the colour of your film. This is a horrible app, and if you do want it, buy full version/ power packs, so you can save your creations. Plus the Greenscreen isnt even that good, and if I want to actually SEE myself+ the backround, there are little green dots everywhere. Sereously. Dont bother.
