There are no absoption balls between Phantom 1 and the gimbal. Thus all the props' vibrations will be passed to the camera. This is a well-known drawback of Phantom 1.
The stock white props may also be not balanced. Most people do not test the props' balancing at all.
8 out of 10 stock or CF props are not balanced. The factories do not test them either.
Post-processing (eg. stablization) is required to minimize the jello/vibration/wind effect. Yes Vision does not have obvious jello effect, but vibration/wind effects are there, since the stock gimbal does not help to reduce these side-effects.
Luckily, stablizaton cures most of these defects.
