http://chris.pirillo.com/ - I recently visited Apple's Headquarters in Cupertino, CA. I took my Creative Vado HD with me and shot this clip.
Unfortunately, I didn't have any kind of stabilization mechanism, so it came out quite shaky. It made for a perfect sample to test against iMovie '09's new stabilization feature. I was quite impressed with the results.
If you don't believe there's much of a difference, keep an eye on the tip of the green 1 throughout the duration of each version. The panning is much more smooth after the effect is applied.
I uploaded this video directly through iMovie '09 and am not too pleased with how it looks here on YouTube. I decided to export the video with default Apple TV settings and upload the same test - since iMovie '09 does not support YouTube HD export options.
