If I buy a memory card for my digicam, will it record longer or more movies?

Bought a digital camera, it only records 12 second videos, and it will only store one. If I buy a memory card for the camera, will it reecord longer and/or store more videos?

Camera is a Samsung S630/S730

yes it will a 1 gb memory is a good size and it can usually record at medium quality for 90 mins. 1 gb cards usually cost 40 bucks. Ask a sales clerk at a electronics store to make sure the card will work for your camera.

depend on size you will buy
