YI 4K+ Action Camera Specs
The camera features a 12,35 MP Sony IMX377 sensor. That’s a 1/2.3″ CMOS image sensor with Exmor R ability, the same one used in YI 4K Action Camera as well as in GoPro Hero5 black.
That’s the major change! The new Ambarella Ambarella H2 chipset with Quad-core ARM®Cortex®-A53 64-bit CPU debuts in YI 4K+ Action Camera. H2 includes 10-bit High Dynamic Range (HDR) video and offers “3D electronic image stabilization”, a better electronic image stabilization now available in 4K with 30fps. YI 4K Action Camera and GoPro Hero5 black hold the older Ambarella A9 processor that limited the frame rate to 30fps in 4K resolution.
Video Resolution & Frame Rate:
4K – (3840 x 2160) – 60 / 50 / 30 / 25 fps
2.7K – (2704 x 1520) – 60 / 50 / 30 / 25 fps
1440p – (1920 x 1440) – 60 / 50 / 30 / 25 fps
1080p – (1920 x 1080) – 120 / 100 / 60 / 50 / 30 / 25 fps
960p – (1280 x 960) – 120 / 100 / 60 / 50 fps
720p – (1280 x 720) – 240 /200 fps
480p – (848 x 480) – 240 / 200 fps
Although the new chipset offers 4K in 60fps, it can’t do higher frame rates in lower resolutions.
.mp4 format, .h264 codec.
Now a bitrate up to 120Mbps is available!
12 MP resolution, so that’s a bit smaller compared to the 16MP photos of YI 1, due to the smaller sensor.
YI 4K+ is also capable of taking raw photos. I hope a firmware update will also bring raw format to YI 4K.

Focal length: 2.68mm
(same as for YI 4K Action Camera)
YI 4K Action Camera also features a display: 2,19″ diameter, 640 x 360 pixel with 330PPI resolution. GoPro Hero5 touch display is a little smaller (2″) and I think the response of the YI display is way better. Hence GoPro’s display is waterproof.
Same battery is used as in YI 4K Action Camera which is a 1400 mAh Li-Ion battery. Battery life is a huge plus for YI! GoPro Hero5 black always ran out first when comparing them. I tested YI 4K vs Hero5 during a 3 weeks trip to Iceland. You can read about my experience in this article.
microSD card support for cards up to 128GB; Class 10 recommended. (U3 recommended for 4K video!)
Connectivity & Ports:
YI 4K Action Camera uses a dual band wifi network (2.4 & 5 GHz) to ensure faster download speeds up to 30Mbps download speed.
The camera features Bluetooth 4.0 for the remote control.
Compared to YI 4K which offers microUSB, YI 4K comes with a USB 3.0 Type C port, which is also used in GoPro Hero5 black.
That allows the use of an external microphone, which was not possible with micro USB.
On the bottom of the camera there’s a door for the battery & microSD card, as well as
a 1/4″ standard photo tripod thread for mounting.
Of course YI 4K+ Action Camera comes with image stabilization, but compared to YI 4K and GoPro Hero5 it is now available up to 4K resolution and 30fps!
It’s a great feature especially for selfies. No need to connect to a remote or smartphone, just shout take a photo and you are good. Very convenient!
YI 4K+ has the same 10 operating modes as YI 4K.
- Photo – to take pictures.
- Timer, where you can set a countdown before a photo is taken.
- Burst, where you can set a a number of photos taken within a timeframe. Max. is 30 pictures within a minute.
- Video – for video recording.
- Time-Lapse Video, where a time-lapse is combined into a video file.
- Slow Motion, where you can do slow motion recording without editing the footage afterwards.
- Time-Lapse Photo, where individual photos are taken, which you can combine to a time-lapse afterwards.
- Loop Recording, where short video sequences are recorded and overwritten once the microSD card is full. e.g. to use the camera as dashboard camera.
- Video + Photo, where there are photos taken in a set interval while a video is recorded. Note: video resolution and frame rate are limited to 1080p 60fps max.
- Live Video (e.g. for Facebook & YouTube Live Streaming)
