I've just taken a gander at the quicktime 6 gallery at Apple, and I guess I should be impressed by the much faster downloading times, but I seem to be seeing many more compression artifacts, in the mpeg4 gallery and with the qt5 content such as the Switch Ads (Liza Richardson looks like she has worry lines now). I suppose I could reboot into my backup qt5 and try to do a comparison, but I just wanted to see what everyone elses impression was. Maybe I am just looking with a more critical eye. Am I seeing things? Also, what isn't in qt6preview pro yet that I could do in qt5 pro?
