If you play the video with VLC it has the facility to take a frame grab.
It's really simple: Menu option 'Video' > 'Take Snapshot'.

It can also be done in camera, e.g. with a K-3, play the movie, pause, and press AE-L (check the manual.)

Ian, I guess if you are posting the question, then you are probably asking for encouragement to upgrade. I agree with the above comments, you probably wouldn't notice the difference in print quality or indeed screen quality of images. It upgrading won't make you a better photographer, anyway, that's clearly not a problem. In any case, it is generally recognised that upgrading lenses can do more for one photography than changing bodies. Having said all that, there are other issues that might be worth thinking about. Let's imagine you upgraded to a K-70 - it's the best value for money new Pentax that is currently in the shops at under £600.

You have identified weather resistance - that's a big plus if you don't mind getting yourself wet. For landscape photography this is a fantastic Pentax feature - but of course needs these WR lenses to make any sense.
The adjustable rear screen is a feature that for me was well worth upgrading for. (also folds in when not in use so is protected)
Improved video resolution might be a consideration
Better low light capability (much higher iso)
More pixels (twice as many) means better cropping options + its a bit like a built in telephoto zoom
Pentaprism always betters mirror in viewfinder (KR) because it is larger and brighter
Focus peaking - especially useful with manual focus lenses
Wi-fi if you want it
Nicer grip
Not more autofocus points but sensitivity improved from -1 to -3 EV
More options in menu
Sharper pics because no anti-aliasing filter
Bigger +/- bracketing range
Pixel shift for super resolution low noise still images
Any colour as long as its black
but most important of all, it does great selfies!

Now if none of the above attracts you, stick with the camera you have and treat yourself to something else.

Only K-r > K-70 drawback I can think of is that it is slightly heavier (+90g)

Now I don't own a K-70, but it combines most of the best features of two which I have - K-S2 and K-3ii. so in a way you get two good cameras in one!

Having said all that, look first at your lenses and ask if they are giving you what you want.

I agree with John when he says "I'm not sure that if one's current camera does what one wants it needs to be replaced."

However, I upgraded 4 years ago from a K-r to a K-5iis, and i justified to myself for two reasons. Firstly, I wanted the WR features of the K-5iis, and secondly I wanted better low light capabilities. I got both, and also a marked increase in image quality.

Am I tempted to upgrade again? Not at the moment, but I would never say never!
