Well I knew that, but nowhere in QT Pro's options does it mention 'Low complexity' and on http://developer.apple.com/technotes/tn2007/tn2188.html it specifically says "The Low-Complexity version of the H.264 Baseline Profile has been defined by Apple for the iPod " which would suggest that it is not standard vanilla baseline. That page refers one to wikipedia for more info: http://en.wikipedia.org/wiki/H.264#Profiles which, in turn, says: "Apple's iPhone and iPod Touch support H.264 Baseline Profile, Levels 2.1 and 3, at resolutions up to 480x320 or 640x480 and bitrates up to 1.5 Mbit/s and is capable of playing the YouTube video content." with a ref to http://www.apple.com/pr/library/2007/06/20youtube.html which is pr fluff and doesn't say anything that specific, and doesn't mention classic or LC at all. I do see in the handy table provided that (number in brackets is max stored frames) level 1.3 = [EMAIL PROTECTED] (6) @ 768 kbit/s level 2.1 = [EMAIL PROTECTED] (7) @ 4 Mbit/s level 3 = [EMAIL PROTECTED] (6) @ 10 Mbit/s which would lead me to believe that that claim is a little far-fetched. It appears a little odd that one can use the straight h.264 option in QTPro can be used to create smaller baseline files than the ipod 'low complexity' option. Maybe low is relative in this aspect? Why don't apple explain things more clearly I wonder Joly --------------------------------------------------------------- WWWhatsup NYC http://pinstand.com - http://punkcast.com ---------------------------------------------------------------
