Slow motion, 4K, and night:


From 4K60P. Neat video was used to reduce noise.

Mark, what's the difference between the 4K+ and the 4K? An extra hundred bucks, and I can't tell a difference in specs or build.

Re: Report on the Yi 4K+
 

The Yi 4K+ has 4K 60P, the Yi 4K only goes up to 4K 30P. Faster frame rate, smoother action.

The Yi 4K+ provides electronic image stabilization in 4K (30P), the Yi 4K does not have stabilization in 4K

You can shoot raw images in the 4K+.

Live streaming in the Yi 4K+ in HD.

Because the Yi 4K+ has a more powerful processor, performance is better in all dimensions - video noise, for example, and faster transfer speeds via usb.

Mark,
Is there a way to run the camera from AC or an external power pack for extended time lapse work?
Special cable, etc?
Thanks.
Ken

Re: Report on the Yi 4K+
 

Absolutely - normal USB-C cable to normal USB 5V AC adaptor, min 1.5 amps, or to external USB 5V 1.5A battery pack. You can run the camera this way indefinitely, even without a battery installed.

Thanks Mark.
I only need to run the camera in time lapse mode for a week at a time, so that should work. Power banks are pretty cheap now.

What are you using as a lens cap for your YI cameras? I found a lens cap/case that's in the $15 range but I have no interest in the case and $15 seems spendy for a silicone lens cap the size of my fingertip.

I find the fisheye lenses on these action cameras get beat up easily because they're convex and they protrude, so I prefer to keep them covered.
