I partially downloaded a movie of a trip to Australia, edited it and exported it to iTunes, so that I could watch it on my Apple TV. I was so impressed with the end result, that I decided to upload the rest of the movie so that I could produce the whole trip. I successfully uploaded the remainder of the movie, but now find that I cannot access the screenshots of the part that I have exported to iTunes. My concern is, that when I export the rest of the movie, will it attach itself to that which has already been exported, or will it overwrite. I know that I should have edited it, in its entirety before exporting to iTunes, but I'm now left with a potential problem. Can anyone allay my fears? What should I do to make sure that I finish up with the full iMovie project.
