Digital Camera straight to the Computer
 

I have a Nikon Coolpix 5600.

Does anyone know if there's any way that I can set the camera to video and just have it recording onto my computer without having to use a memory card? All I have is a 256mb and that provides about 6 minutes of video.

does the camera have a video out jack? If so, and you have a video capture card on your computer, you can do it. Otherwise, snag a bigger memory card. $70 max will get you a gig.

I'm going to guess you're out of luck on this one. I haven't heard of such a feature.
I own a Coolpix 4500.

I don't know the spec on the camera but with my Sony DSC-P1 the best video resolution looks pretty bad after convert all the clips to DVD or SVCD. If you want good quality video it's better to get a camcorder.

Even if there is such a cable that allows you to record straight to your PC, are you going to carry your PC around so you can shoot clips? Get a larger capacity memory card, check out the largest possible that is compatible with your digital camera though.
