I bought a ScanDisk Ultra 16GB card. I was not aware of the classes...it is a class 4. I figured it was the best since it was $90. I switched from using the 5 (1080) setting to the 4 (720) setting because the 5 setting was a little choppy. I guess I need to play around with it a little more and figure out if it is my computer or the card.
I uploaded a video to youtube using the 4 setting from the eyeofmine case. I noticed a white ring from the video. The instructions told me to black out the silver ring around the lense. However, I never noticed it before I put it on youtube.
The 4 setting really looks great on my computer and when I burn it to DVD. However, obv I would like to use the 5 setting if it is smooth.
