I wasn't trying to turn this into a video thread, just thought it was interesting in regards to what most people's interests are here.
In regards to still to video and file size, well you can never have too much data, not matter what the final or how small you will rez it down.
This was done for our reel and shot with a p21+ and Contax. I like the look.

(The banding you see here comes from the web purposed clip which is of low bitrate.)
If I had time I'd probably go back and processes it out flatter to kill some of the banding, though in full 4:2:2 pro rez it's fine.
Anyway, a lot of video we have done through the years are moving more and more to multi media projects and less pure motion only pieces, because the world of imagery has become more multimedia in style.
In fact when we have a brief to shoot only motion we sill cover every scene in stills and it is always picked up and used.
In regards to RED our cameras have a lot of dr truly useable 14 stops, but RED is more tilted towards the highlights where the Arri is more tilted towards the whole range.
DR talk, still or motion, of 12, 14 to 18 stops sounds good on paper, but a lot of that talk is just that, on paper. It's what those useable stops look like.
I don't find it a one camera world yet, or where a digital motion camera can produce stills the quality of a dedicated still camera.
Even cameras like the Panasonic g3 which is probably the best of the low cost hybrid cameras has tilted there efforts towards the motion imagery more than the still imagery.
Olympus with there new 4/3 camera took the opposite track so maybe it's not possible to optimize the camera to do both well.
We'll see.
IMO
