I would like to submit a suggestion to integrate an accelerometer (dirt cheap) into the camera hardware. The acc data should be recorded as metadata, in sync with the images and preferably at at least twice the frame rate. This data could be used in post production to stabilize handheld footage or for special tracking needs in high end post. Please consider this, as the hardware should be cheap to add and the metadata would offer lots of opportunities for experimenting in post.
Cheers, George Tyszkiewicz
Apertus Axiom rocks!
