If you mean discrete frames you could extract in post- yes of course. If you mean stills that are larger in resolution than 1080p or 720p- no. For that- you should have a dedicated digital still camera as that is what they excel at. That said, I’ve gotten excellent 300 DPI stills with post sharpening out of the SDX900 which is 480p. So I’d expect even better results from 720 and 1080.
