I am trying to save a 35 min project as a Movie - as High Quality Video - Large, which gives great quality in manageable file size - 450 mb. It says it saves to 100% but on viewing Movie it gets hung up about 20-30 mins in, it stops on different scenes each time, the music continues. Should I cut the movie in half and save each half? if so, how would i do that? I am going NUTS! Thanks!
