This is my 2nd Pokémon themed Adventure. I'm kinda happy with how it turned out however you'll notice the green screen representing the bottomless cave is awful. I only use iMovie and their green screen settings are pretty basic. I have however downloaded a free trial of VideoStudio Pro - has anyone else used it? How good is it? Would you say it's better than iMovie? Will it offer green screen effects that don't make my vids look like amateurish crap?
