Ok I think you answered my question with your post.
So, shutter speed and the resulting sharpness of frame grabs will not really have anything to do with shutter speed we select in video, fps is all that matters!
If I understand the above correctly... the opposite!
Think of the video frame frame as being how often you press the shutter button. The shutter speed is how long the shutter stays open, and that's what will control sharpness of moving objects.
A high frame rate simply means you're taking more photos per second.
What you can't do is have a shutter speed that's slower than the frame rate, as the camera couldn't take enough frames in the time required.
For video work, a shutter speed of twice the frame rate (e.g. 1/50th for 25fps) tends to make what we consider "natural" video. For screen grabs you'll likely want a higher shutter speed to get sharp individual frames, at the expense of slightly odd looking video.
I suppose in time someone may develop tools that look at video frames and smear them such that you can take 30fps video with a 1/1000th shutter speed (for sharp stills) but then produce an edit that looks smooth for video playback. Someone's already mentioned the possibility of cool stuff with Twixor.

I also think composite photography is a joke as well but I'm not going to go off topic.
Remember that Ansel Adams did an awful lot of editing in his day

I'm not clear on why Canon's 4k file size is 4 to 5 times the size of Nikon & Sony? And if I read the reviews correctly, the extra large files provide nothing in return except to be a PIA in processing and taking up enormous capacity on your cf cards.
Maybe I missed it in this thread.
It effectively stores a flick book of individual JPEG photos, with no compression of moving objects between the frames (i.e. it's interframe only, rather than inter and intra like MPEG).
That makes it good for image quality and extracting stills, but not so good for compression (the file sizes are big).

IQ was the same.
I expect the mk4 to be only slightly better in IQ.
I'm not expecting huge high ISO improvements, but I am expecting some serious steps forward in low ISO DR and noise character. The 80D and 1Dx2 have achieved that; I want that too!
