Nice video. We bought an HV30 a few months ago, and my son and I are dabbling with it (him more than me). He wants to do the slo-motion test as well. We have Sony Vegas Pro 8, and we just haven't taken the time to do it yet. We know we can easily CTRL- click to change the duration of an event, but I was wondering if you've found any "best" shutter speeds for slow-motion (and heck, for fast-motion, too - we're thinking of videoing us doing yard work, then speeding it up to a very short, fast clip).
BTW, we love the HV30, but it's amazing how fast the AVCHD stuff is catching up now. We chose tape because we both want frame-editing, but the bit rate on the AVCHD is now very good. Ah, well, what can you do.
