TOPIC: ‘‘Frame Grabbing’ of 4K (and up) videos’
PREFACE: I have had excellent success by Videoing an event like a Graduation (using my 8MP Apple IPod Touch); and then I would use the IOS App called ‘VideoPix’ to easily view each frame in the Video, which I had captured to my IPod’s ‘camera-roll’.
=============
I then would determine which ONE frame shows the ‘precise’ moment that ALL THREE of the following are happening SIMULTANEOUSLY:
1. The Diploma is in both the Presenter’s and the Graduate’s LEFT hands; ...and,
2. The Presenter and the Graduate are shaking their right hands; ...and,
3. Both Presenter and Graduate are simultaneously looking at the Videographer; ...and,
4. Both are Smiling.
=============
I would NOW like to upgrade to a Camera (...or Camcorder ...or
Smartphone) that Videos in 4K or 6K or 8K.
=============
That way I can offer my client a HIGH Resolution 11 x 14 (or Larger) Portrait.
=============
I know that a 4K Frame yields a 8MP STILL; ...can anyone tell me what size ‘Still’ is produced by a 6K and 8K video frame.?
=============
There is an excellent treatise on the subject, however it’s now effectively three years old (March 2015)

=============
Another ‘solution’ to capturing the ‘precise-moment’ MIGHT be to use a camera like the Sony ‘a9’, which operates at 20-fps.
