1. The player for the iPhone movie is Quicktime, while the 9630 is on YouTube. Flash can really degrade the quality of videos, even on high quality mode.
2. The iPhone shot was longer and mobile - it showed different areas. The 9630's video showed a limited space with not much movement, so it was hard to see how other places would look.
3. Although the lighting on the 9630's vid was good, the iPhone's lighting was SUPERB... bright sunlight. You really can't beat that, and it's the optimal conditions for filming. And the more light, the better the quality.
The video recording on the tour is really good.. as stated youtube downgrades the video but having used the tour for video alot on a recent NYC trip I can tell you it doesnt a very serviceable job.
