Picasa has added a new feature in version 3.8 that creates slide show movies that synchronizes faces. I took some photos from a kids birthday party this weekend and added some music to come up with this demo.
My only trouble was in synchronizing the music. Picasa couldn't seem to figure out how long the music track was. I started with a Variable Bit Rate mp3 file and thought that might be the problem, so I switched to a fixed bit rate version. Still Picasa was wrong about the length of the track in the preview mode. I did the calculations manually and pressed the "Create Movie" button and all came out well.
