"Timed Shot" - very limited interval

I was was already surpised when I tested my Inspire 1 Pro a year ago. While it is capable to record 4K video, it cannot shoot more than one image every two seconds.

Now I must learn that the exact same limitation applies for the P4P too.
Why?

Why is it possible to record a 4K / 60 frames video and, at the same time, it takes 2 seconds to process/store one single still image (jpg). Even worse, when it comes to RAW/DNG: The minimm interval is then set to 5 seconds...

The SD card cannot be the limiting factor, that's the only thing I know for sure.

(With my 6 years old Olympus E-M5 camera I can shoot 2 images or more every second for an unlimited time, using average-speed SD cards.)

Simple answer is a video frame contains about a tenth of the information that a still image has. If you ever compared a single video frame against a still image you'll see how poor it really is. A TV is pretty poor on quality against some high resolution printer where you can see individual strands of hair which is almost impossible to see on a 4K TV.

Plus, the rolling shutter for video takes about 1/10 second to scan a video frame even though your shutter speed might be set to 1/8000 sec. Try to do that time with a video frame to equal a still resolution would make it about a second or slower with the buffering.

More explanation is here: Camera/Still Resolution vs Video Resolution

Thanks for your explanantion.

I'm not expecting a 60 shots per second frame rate for 20 MP still images, of course. But maybe 1 or 2 images per second, that's feasible and pretty common, even for lower-end compact cams.
Example: "Canon ELPH 350 HS's max continuous shooting speed is 2.1fps slower than the average Compact camera shooting speed."
