Aircraft and the Twin Towers

Optical Image Stabilization (OIS):

Abbreviated as OIS, optical image stabilization is the apparatus, contained within a digital camera or other digital recording device, that compensates in real-time for shaking and vibrating while recording. Because OIS is a real-time compensation there is no alterations or image degradation to the image.

yes, but....that is a fairly new technology [post-911, I believe] and mostly applicable to still photography, rather than motion video....it can compensate for vibration, slight movements of camera and/or object, but not vertical or horizontal motion of where the camera is [as for example in a helicopter]. If this was used before release in the public domain, it would further point to military/intelligence assets using it - as they usually have such things a few years before its known or available in public. I think, however, if real, this was filmed from a non-moving platform - or one moving level toward or away from the optical target [i.e. again having some foreknowledge]. Images can also be somewhat 'stabilized' after the fact now using digital processing...but again the same caveats apply as that done in a device.

I'm not sure that is the case. I saw a TV clip many, many years ago that showed this technology in operation. It was used by a TV camera in the African bush mounted on a 4 x 4 shooting footage to the rear out of the back of the Land Rover. In the first run without the OIS operating it was the bumpy jumpy footage you'd expect from live action. In the second clip with OIS activated (the same run btw), it was perfectly smooth and stable - no bumps, jumps, vibrations or jolts at all.

It can't say how long ago this was, but it was a long time.
