I have a few questions about making the switch to HD...

Currently I'm using a 3 CCD Panasonic MiniDV now and am pretty happy with it. I am curious on a few things.

When I capture film onto my comp it is typically 20 gig for about an hour of video... if i up it to HD will it jump the disc space a ton?

Also along the lines of that question if you shoot in 24p is the disk space required lowered because its 80% of the # of frames?

Thanks guys!
