Official!

YI Technology, the leading, international provider of advanced, intelligent imaging technologies, today announced plans to unveil the YI 4K+ at CES 2017, the first action camera to capture 4K photos and videos at 60 frames per second (fps). The company also plans to fly the YI Erida drone, the world’s fastest tricopter, for the first time live in the U.S.

“2016 has been a whirlwind of product launches including several new action and home security cameras, the YI Erida drone, our first mirrorless camera the YI M1, as well as an exciting partnership with Google to develop a virtual reality camera rig,” said Sean Da, CEO of YI Technology. “CES 2017 is an important milestone for us as we look to demonstrate our full product line and reveal novelty solutions. As a challenger brand in the changing imaging technology market, we are constantly looking for ways to push the boundaries and set new standards for the global industry.”

Based on the award winning YI 4K, the YI 4K+ is the third action camera in YI’s successful line of high quality and affordable solutions. The faster frame rate of 60fps is double that of competitor’s products and allows for more realistic, high quality video content.

YI will demonstrate its full line of connected imaging technology solutions, including the YI Erida drone, YI 4K+ Action Camera, home security cameras, dash camera, and the professional grade mirrorless camera, the YI M1, at two different locations during CES 2017:

Pepcom’s Digital Experience!: Wednesday, January 4, 7pm – 10:30pm PT, The Mirage Hotel The Sands, Tech West: January 5-8, Booth #46324

The gimbal comes with two batteries and a two-battery charger. The batteries are supposed to last 12+ hours. I did not test that (a waste of my time), but basically this means that even if the actual time is 8 hours and not 12, you can just turn the thing on and leave it on all during your shoot. Again, you can just treat the gimbal like it was a stick. No worrying about power. Leave it on, forget it uses power.

The form factor is like any other 3-axis gimbal, with perhaps a longish handle (to fit those batteries). It has a joystick for pans, tilts, etc. and for selecting one of three modes, just like all modern motorized gimbals. The motors are basically silent (I can't hear them). But...

The way you mount the camera is to push one end of the camera right up against one of the gimbal motors (the tilt). This gives the best balance, and also makes it easy to figure out how to place the camera. However, one of the two internal mics of the Yi 4K+ is on that side! With the mic pushed up against the motor, guess what? - you get motor noise or at least motor vibration noise. You cannot therefore use the internal mics for audio while using the gimbal. Hence, you need to use an external mic. And the Yi 4K+ can take an external mic (mono).

My small and lightweight portable "kit' consists of the Yi 4K+, a Sony ECM-CS3 mic and the gimbal. Why this mic? it is tiny and light and, most importantly, has an alligator clip that lets me attach the mic directly to the brace between two of the motors - on the gimbal. Not the handle, so no handle noise, and as I said, the motors are basically silent, so no motor noise. My kit therefore gives me quiet (and good) audio, better stabilization than any camera or camcorder (BOSS, IBIS, whatever) with no digital degradation, and 4K video at 60 fps. The camera is $339, the gimbal is $178, and the mic is $17. Perfectly stabilized handheld video, allowing camera movement, audio with no noise and 60 fps 4K for below $550.

Why is 60 fps important? Well for normal video, you get smoother motion. But, more importantly, you can slow down the video which really smooths out movement with the camera, and you can still have 4K (at 30p).

Ok, maybe I am just a shil, trying to sell you on this combo. So, really, how good is the 4K video? is the audio really without noise? can the gimbal really give you steady handheld shots? how smooth is the movement?

See for yourself:

The Youtube version streams at 2160 60p, and if you have the bandwidth, you should choose that setting to view no matter what the resolution of your viewing device (monitor). If you cannot do this smoothly, try 1440 60p. You will see that Youtube compression does NOT ruin the quality (and that a true 4K video looks better at all viewing resolutions). This video has static shots and walking while shooting, and for audio - a saxophone, guitar, fountains, and construction noise.

I don't know if the Vimeo version streams at 4K 60p (it certainly streams at 4K), but you can download the original 173 Mbps UHD 60p original (as I made it).

How does walking with the camera look slowed down? This video was rendered at 4K 30P, but contains slowed down portion so you can see the effect:

In these shoots I did not once expereince any gimbal glitches (sudden spontaneous gimbal movements). Oh, and there is a bluetooth remote for the Yi 4K+, so you can start and stop the video without touching the camera. It works fine.

And here is a test vs The Xiaomi Yi 2:

I ordered my H8 Plus (with 720p240 and 1080p60 stabilized) for 119$ on banggood. There is a "ProTune" mod in the works here: https://dashcamtalk.com/forum/threads/eken-h8-pro-finally-real-4k.21605/page-2

Adding a 36$ 90°FOV lens, and some higher bitrates, this thing is a brilliant bang for the buck! Anyone have any experience with it?

Everything is in excellent condition and it comes with original packaging.

PM if interested.
