Can someone educate me?

This question is by far a background question, but if some kind sole could point me at a read I would be grateful.

In still mode the lens focuses on to the full sensor surface.

In video mode it must do the same thing.

The question is: how is the video recording handing the differences in pixels recorded, eg does video 'simply' bin pixels? And if so is there an advantage in S/N, ie more captured photon at each site.

As I say, a background question.

My best guess: http://www.magiclantern.fm/forum/index.php?topic=10111.msg118232#msg118232

It's only halfway confirmed experimentally; I'm still waiting for some tests, so feel free to contribute. No need to compile anything, just take some pictures in some controlled settings, as described in the thread.

P.S. next time please use meaningful subject headers.
