thanks for getting back to me!, It was the trial version of snap that I used so I don't think it gave me an option other than the quality ratio, the trial version was suffice to get what, I needed, all I know is the file states. .mov and yes after exporting all i see is a black blank movie, yet the audio attached via imovie plays. not sure what codecs is??? is that the small medium large for ipod, apple tv etc? It only gave me the options of small and medium. info says on the movie fileKIND: quicktime movie Size 370.3mb, dimensions 639/479 CODECS: Animation!
