I just checked the Optio 750z. At 640x480 and 30FPS, a 1GB card provides 15 minutes and 24 seconds of video. It's in Quicktime (MOV) format. I don't think I'd recommend this camera if you're going to be taking a lot of video. In addition to the short record time, you have to hold down the shutter release while you are making your movie. It's very awkward.
