It may be out of the quest

It may be out of the question, but at the just ended NAB Post in NY, Olympus was showing a DV camera that could shoot thirty thousand frames per second (it scaled the picture at that rate but did a full 720X480 at lower-but-still-higher-than-normal speeds).

I’ve also been told that HDV is not ideal for fast motion (like pans and such).

Just a thought – It was very pricey as I remember though….
