What's the frame dimensions for 4K in Pentax? According to this link:
What is 4K Video | 4K Download Full Aperture 4k | 4096x3112 | 12,746,752 pixels |
Academy 4k | 3656x2664 | 9,739,584 pixels |
Digital Cinema 4k | 4096x1714 | 7,020,544 pixels |
Digital Cinema Aperture 4k | 3996x2160 | 8,631,360 pixels |
4K means it has approx 4K
horizontal pixels, not the number of
vertical pixels like in "1080p".
Not sure about the frame size yet. It's not mentioned in the K-3 manual. It looks like 16:9 and, if it uses square pixels, it would be probably be 3840 x 2160 = 8,294,400 pixels per frame.
Since it was originally shot in Motion JPEG (for interval movie mode only), the original video should have been very HQ, but enormous.
