Ok, I had a break to investigate a bit.
The content of the article in EOSHD is absolutly correct if readed carefully. You have the answer in the Samsung executive interview that's linked and saw a couple of clarifications in some spanish sites too. What leads to confusion is the EOSHD article title.
This camera is interesting and at the same time not. Interesting because it's a glimpse of what's to come (the guy's article also says that), and not, because it's just a glimpse.
So what it does is this:
- the camera processes a 4K (12MP) image 30 times per second.
- It writes on the sd card a donwsampled 1080 footage (from this? mystery)
- whenever you click while filming, the camera would write a 12MP still image too without interupting the filming.
In other words, you can film HD and do 12MP stills works at the same time. No dslr features that, that I know, and I doubt any compact today. If I'm wrong please correct me.
This is a unique feature indeed being able to film and do a truth still work at the same time, imagine that in a 5D2, that truly can be usefull but it's obviously not 4K video, and the original from what is donwsampled to full HD remains a "secret" to date. (the Samsung executive doesn't want to reveal too much on that matter)
So I have to rewrite my post title. There was indeed a semantic confusion.
At the same time, it is interesting to note that such a compact "toy" is able to process 4K at 30/sec, and the question that asks the guy's article seems to me appropriate.
Back to work. Bye.
