Using iPhoto 2011. I was going to export my slideshow as a Quicktime movie, then burn it to DVD in iDVD.
However when I get 3/4 of the way through my 20 minute slide show presentation, the video goes white. I have figured out that the slideshow ends but the export keeps on going. I think it has something to do with the synchronization between music and photos.
My slideshow is approximately 22 minutes long, and I have a playlist of songs attached to the slideshow. The option to sync the pictures to the songs is checked. The slideshow works perfect in iPhoto. But my exported video is longer than the pictures.
