Since YouTube announced they are now hosting HD videos (YAY!), i’ve been playing on my Mac with getting the optimum settings for high quality uploads. As a heads up for those also setting out on the HD adventure, i’ve used these settings with great results from my Xacti HD 2 and Flip Mino HD.
Hope this helps someone! 
One word of caution – even on my quad core beast, these settings take a little while to encode! The end result is worth it though, and seems to be free of the sound sync problems i’ve experienced with other configs.
If you have any better settings, let me know!
