  • A simple 2.7K 50p/60p mode with low compression. Thats honestly all that attracts me to the GP4 now. Why can't one company make this ?

    Do not worry, upcoming sensors and chips - will do many things.

    May be it even will have mode you so wish, and bitrate will be certainly hacked.

  • I hope they improve dynamic range this time... I hate images that look like a cell phone vídeo.

    It was for the original Xiaomi Yi camera.

  • Announced officially - price is not so small - around $200

  • '7 layers all glass lens' and it's still a fisheye?

  • Is there 24p mode?

  • I especially like the "daily impact" and "fashion accessory" features. Though seriously I think I am gonna try one...might even pre-order. For the stuff I do (fishing) the 240 fps at 720p could be really good.

  • In the video comments it says they will be adding a protune-style recording mode.

  • US press release

    SEATTLE--(BUSINESS WIRE) -- Just in time for Amazon Prime Day on July 12, YI Technology, the leading, international provider of advanced, intelligent imaging technologies, will launch the YI 4K Action Camera, the latest in its successful line of action and home cameras. The new device is the only action camera on the market today that combines 4K30 video recording, up to 120 minutes of recording time and an integrated, high-resolution touchscreen, all at the unmatched price point of $249.

    The YI 4K Action Camera will be used later this year as a core component of a virtual reality camera, developed by Google and YI. The camera will support 3D-360-degree imagery for virtual reality capture and experiences. This partnership was previously announced at Google I/O.

    The YI 4K Action Camera is built with Sony’s 12MP IMX377 CMOS image sensor and the latest A9SE75 processor from Ambarella, allowing users to capture and share moments with increased speed and lower power consumption – including 4K30 video recording at 30fps. The built-in Lens Distortion Correction and Electronic Image Stabilization mean videos are clear and natural. And when it’s time to slow the action down, there is a built-in Slow Motion mode, with no need to edit video later.

    “Today’s action videographers demand both long recording times and the best image quality,” said Sean Da, Co-Founder and CEO of, YI Technology. “That’s why we’ve packed the YI 4K Action Camera with the best components the industry has to offer, to deliver truly outstanding performance at an affordable price.”

    But shooting thrilling videos is about more than just images. That’s why the YI 4K Action Camera features a new, integrated dual microphone, so movies have audio that is just as clear and vivid as what is on the screen.

    Controlling the YI 4K Action Camera is a breeze thanks to its integrated 2.19-inch, 640x360 resolution touchscreen at 330ppi. With a full 160-degree viewing angle, the display ensures users can preview their videos on the fly and never miss a shot. A Bluetooth 4.0 remote control is available for shooting from a distance. And the accompanying apps for iOS and Android allow people to not just shoot, but also edit and share professional-quality pictures and videos on the fly – no separate PC needed.

    “The action camera market is still a hotly contested one, with established players meeting challenges from emerging entrants,” said Alan Bullock, Associate Director of Connected Imaging Trends service, InfoTrends. “YI Technology’s entry into the 4K action camera field is sure to heat up that competition as consumers demand ever more features and higher overall image quality.”

    A wide range of YI accessories that are compatible with the YI 4K Action Camera are already available, including an expandable selfie-stick, Bluetooth 4.0 remote control, waterproof camera housing, and a harness for wearing or mounting the action camera.

    YI Technology already offers its core products such as Action Camera and Home IP Camera internationally. YI cameras are powerful and lightweight and packed with industry leading image processors and all products offer the ability to capture full high definition videos and photos.

    Later this year, YI will release a developer kit that will allow even more innovators to use its camera technology in exciting new ways.

  • Wow, thanks. Need to try it.

  • Yi 4K Action Camera vs Samsung NX1

  • Still did not get it. Hope to find detailed review on all aspects of this little cam.

  • I do not see anything innovative here: No 4K60p, no HFR beyond 120p, no 2.5K at 60p. And, of course, the stabilization does not work in 4K (neither does the distortion fix or low light). So, this is just a knock-off of the Hero 4 Black, with some nice features (LCD), but indeed at a very good price and the quality in 4K looks good.

    The Sony FDRX300 (available in Japan) has BOSS stabilization in 4K - that's an innovation.

  • @markr041

    Are you sure? As BOSS is gimbal like stabilization in their video line.

    Most probably it is juts optical and electronic stabilization.

  • Well, here is the Google translation of what Sony says:

    "Even moving the camera body, float in space the optical unit of the lens and the sensor as an integral, are mounted on the Handycam of Sony "space optical camera shake correction". It was equipped with newly developed ultra-small size of this unique technology for the action cam. In addition, we realized the blur no stable recording than conventional by tuning the correction capability for the action cam. Such as a bicycle or drive, you can also stable image is to reduce camera shake and blurring the scene blur occurs. This overwhelming shake correction function, users can be working in 4K shooting and high-speed recording." [emphasis mine]

    And here is the link to that page, with a diagram of what is going on.

    Seems like free-floating sensor/lens to me, just like BOSS. And that it works in 4K (which for sure it says it does)suggests that it is purely optical/mechanical - no digital at all.

  • Yes, big thanks.

    It is very good system. Best stabilizer amount all camcorders.

    Only gimbal can compete.

  • New beta firmware for Yi 4K have flat color profile, can be obtained at
