Xiaomi Yi 4K the GoPro 4 Killer

As I remember, Xiaomi Yi was the first camera that I introduced here on Best Action Camera. Now it’s time to write some words about the newer upgraded Xiaomi Yi 4K model. In my opinion, this Yi 4K camera 2 looks like a completely new product, not like an upgraded version of its predecessor.

Unlike any other GoPro clones, this Xiaomi Yi 4K features a generous 2.19″ live-view LCD screen with touch screen and Gorilla Glass.

Thanks to the Ambarella A9 SoC imaging processor, which is also used on the GoPro Hero 4 Black edition, this Xiaomi Yi camera 2 is capable to record videos with 4K resolution at 30 frames per second.

While the previous Xioami camera featuread a 16 MP Sony imaging sensor this new Yi 4K features a 12.53 MP one (Sony  IMX377).

In order to record some cool slow motion footage, this camera allows to capture Full HD 1080P videos at 120FPS and HD 720P videos at 240FPS.

As I’m a drone enthusiast, I’m curious if it will have AV-out for first person view flights.

Images with the Xiaomi Yi 4K cam


  1. It not has exactly the same CPU as the GoPro 4!
    BTW, the estimated price of the Xiaomi Yi 4K is $ 250, pretty expensive for a Chinese product…

  2. Used both GoPro 4 black and this Xiaomi Yi 4K.
    I find it really good. Could not complain. As DoBro said expensive for Chinese. He may have issues based on his experience but gopro4b is also made in China by “American company”.

    I liked it on my bike & in car results are as good as GoPro 4B

  3. The real question is the video out… it look amazing… but will we be able to connect to USB and see what we are capturing is the question I want to know.

    The new stabilisation also looks amazing.

  4. Apparently there will be a usb cable for av out but it may not be out yet.
    I’m looking at my options to buy a cx-20 or similar quadcopter and add the yi 4k camera to it for fpv but I’m still looking.
    Where do you guys hang out mostly? FB? G+? Tw?
