So I love the iPhoto "ken burns" slideshows, and I had created a cute one set to the "Linus and Lucy" theme song. However, when I exported it to a .mp4 and uploaded it to YouTube to share on my site, I got the "copyright" warning and the audio is disabled. So anyone know what the copyright limits are as far as slideshows are concerned? What's the point of allowing us to use it if we can't share it? I also noticed that the quality is degraded due to compression... would it be better just to make my own slideshow in iMovie and share that instead (quality-wise)? Or is there a better way to share the slideshow?
