I didn't format the card 1st and it cost me my video. Don't do what I did; format the card then use it (Windows PC) I'm not sure if you have to format 1st when using MAC. I used a PNY SDHC 16gb card and it did just as good as the SanDisk and it cost about $15 less, I think that's the better way to go, you're getting the same results just not as long of video time.
