I'll be happy to post some video once I get the camera. Unfortunately, Amazon expects it to ship within 1-3 weeks and I only ordered it on Thursday so I might be waiting a while.
In the meantime, I'd suggest you pop over to youtube and search for 'zi8'. There are plenty of sample videos available and now that youtube does HD the quality is pretty good. There's sometimes a bit of jumpiness regarding frame rate, but I'm pretty sure that's just due to the conversion from raw video to youtube video. If you check out the samples, you'll notice that there are some that look perfectly smooth and some that are shaky as all hell. If you're planning to walk around with the camera while filming, be prepared to have some pretty shaky footage. If you're going to stand still and plant yourself for a shot, then I think you can get some really great footage with this camera. But, I guess I'll know for sure in 1-3 weeks!
If anyone happens to see this in a store over the next couple weeks, let me know as I'll gladly cancel my Amazon order to get this puppy sooner!
