If you're not sure, I would consult with a member of Geek Squad, or someone that works in the camera dept. at Best Buy. They're very knowledgeable about the products they sell, and can give you a more definitive answer to your questions. Video uses more space than pictures and music, so depending on the amount of GB's your card has, the higher the better. Also, good idea to check your owners manual to see if there are any limitations on what kind of SD card to use. Cheers!
