I think You can set it on Low-Res Video and High-Res Video,the Low-Res video allows more video to be stored in memory but the quality of the recording is less than the High-Res video's.You may want to use a higher gig card if you plan on using your camera in video mode because it will use up more space faster.Your Moultrie Instruction Manual will have the different spec's on how much Pictures/Video's (Time) is stored on Internal Memory,and a 256MB SD card.You can also go to the Moultrie Site to see the info there on your model of Camera.
