Yes, they can be used for both video and stills, but they are optimised for their main usage. A video sensor will be low res to avoid line skipping as an example ?
Video sensors are no different than stills sensors but video sensors need to support much higher read-out speeds (60-120 fps for video vs 10-12 fps for stills).
One way to cope with the data throughputs at such speeds is of course to have a lower resolution sensor or to do line skipping (or 'thinning', as I've seen it called).
This is something that technology will definitely solve in the future, though.
A hi-res sensor designed to do pixel-binning (or some other trick) instead of line skipping will avoid many of the aliasing issues that current DSLR sensors have for video.
The Reds, and the other dedicated video cameras have a video specialised sensor and I am claiming that they are more expensive due to this.
I disagree with that.
Economies of scale surely play a role in sensor costs but the REDs are so expensive mostly for business/marketing reasons.
RED are establishing themselves as the Ferrari/Lamborghini in their market.
So, you will never see low cost cameras from them.
