720p videos using class 2 vs class 6 SD memory cards

[ericmcintire]

Just made these 2 videos, tried as hard as I could to duplicate the videos using the same lighting and audio levels.. The first one is with the 8GB class 2 microSD card that comes with the phone, the 2nd one is the 8GB class 6. I killed all applications and booted video camera both times, I tried to eliminate all variables, same phone was used to make both. Let me know if you guys can see a difference in either one..

Any tips or tricks to up the quality at all?
