This is from 4K video.I realized you can't enlarge it cause it is not online. But detail is very sharp like yours.

In between i only take images from 4k videos, this gives me the possibility to get the perfect moment (for example like the moment with a short reflection in the eye of the Silverback or a cool fascial expression). Of course these shots are only in 75 dpi, but the image quality in full resolution is so amazing, even after additional stabilisation with Mercalli plugin. I never got a nearby HD quality of video images from HD camcorder.
Can make also single photos with 300 dpi, but that's not the (my) job here! ;)
I'm sure that your FZ1000 shots should offer the same quality. As i wrote you before, at any time i'll buy it as secondary camera for inkognito walks.

You are absolutely correct. Panasonic's 4K camera is exactly for this purpose. Take your 4K video and extract the image from it. The image quality of 4K is good enough as a 8mb picture. That is it.
