I am trying to practice animation and copy the idea of a baloon floating over clouds. In the white areas of the gif I can see some of the sky behind. It does not do that in a photoshop layer. I also tried to save as a png withe same result. How do I save the file so parts of the image are not transparent?

Ability to add overlay narration via the main window "sound" line which spans more than one slide. Yes I copied this from another post, but I think it is extremely important. If you add sound to a slide, the next slide cuts it off even if there is no new sound. When would you ever want that to happen?
