I import an audio file and it shows up in Audio Track 1. I then start to import images. Is there an automatic feature that will set the duration of the images to synchronize with the length of the audio file? If I have a song 120 seconds and load 10 images they would each have a duration of 12 seconds. If I load 20 images they would each be 6 seconds long. It would be a lot easier than trying to click and drag each image to fit. I know there is an option to set image length but you have to set it before you load images. Thanks
