Hello, I have searched for this, but, I have not been able to find an answer. I have put something together using the earth on iMovie, and I have added all of the city pairs that I would like to have. I am somewhat short of what is needed to take up all the time for the music. Is there an automatic way to set all of the slides timing to match the entire length of the music track I have added to my iMovie? Thanks in advance.
