I am new to FCP after many years of linear editing, then using a Casablanca Avio. Anyway... after capturing footage from my camera, all the individual scenes (about 50 of them) were broken into clips. Now I'd like to put in 1/2 second dissolves between each of the clips. I know this is easily done in one fell swoop in iMovie, but can it be done in FCP? Do I first have to trim each and every clip by 15 frames at the beginning and end of each clip, and is there a way to do that all at once or quickly?
