I really hope this keeps being optional because otherwise a lot of the authentic value of the videos will be lost. Also, the demo they showed looked like it was algorithmically deteriorated to make the change more noticeable. There's shaky hands and then there's parkinsons-level shaking which was what the demo showed...

"...algorithmically deteriorated..." Or the person holding the camera was shaking like mad to demonstrate the abilities of the algorithm. Artistically speaking, shake removal is also authenticity removal. But most times, personal videos are shot by people with no eye for framing and stability. And most times, artistic (and professionals) videos are shot with an eye toward these things. I can't foresee a reason not to…

If you look carefully, the shakes appear too uniform to be a person shaking the camera. It looks like the camera always "shakes" in a circular motion around the center of the original camera location.

Probably a staged setup, inducing a regular shaking pattern, but I think generating rolling shutter algorithmicly would be a stretch for them, so I call physical but maybe voluntary shake.

Seems to work well- I just tried it on a tiger cub vid, which I've had for years and was taken with an el-cheapo digital camera: Shaky version: http://youtu.be/g5P9WwHdOSI Stabilised version http://youtu.be/wXfbRUk_1Bg

There is some motion blur (around 24 seconds, when the momma tiger lies down) which is a bit puzzling once the image has been stabilised. But hey, it's better than it was before.

They should apply this during movie fighting scenes. Then we might actually see the fight instead of the blur caused by "exciting cameras".

I wish my tv/movie playback devices had a "de-lensflare" filter.

Are you referring to JJ Abrams recent flirts with anisotropic lenses?

I'd like to see this come in Android so you can automatically shoot and record videos without the shaking in them. It would be a great selling point in my opinion.

You should already start to see that working its way out: the iPhone 4S does video stabilisation, I am sure high-end Android phones do or will start to do the same.

The algorithm being discussed here is specifically designed for when information about the camera or environment is not available: there are much better ways of carrying out digital image stabilisation on the device itself, such as using the accelerometer data to compensate, or in significantly advanced cameras (DSLRs, for example) compensating by moving the lens itself.
