Video length：5 min, 20 min, 60 min, 120 min, Max

Built-in 3 axis gyroscope and 3 axis accelerometer. Uses a cross-border compensation algorithm to compensate the motion change to produce stable video quality

Resolutions supported：2.5K/30FPS, 1440P/60FPS, 1080P/60FPS, 1080S/60FPS, 960FPS/60FPS, 720S/60FPS

With a normal camera, the user must manually adjust the parameters according to different light conditions. YI 4K Action Camera makes it easy for you, it senses the change of the light condition with CMOS, and ISP processor will adjust the frame rate and parameters automatically and to produce the highest image quality at low light.

Shutter settings：Auto, 2s, 5s, 10s, 20s, 30s

Shooting speed：1/4096s to 30s

YI 4K Action Camera has multiple high-level settings such as shutter at an exposure time of 30 seconds; Exposure Value compensation setting (EV), Setting of level of sensitivity (ISO); Metering Mode; White Balance (WB); etc. Together with the choice of 9 shooting modes, you can make impressive work like a professional photographer.

Users can adjust the white balance settings to change the overall color of the video or photo.

Change the camera photosensitivity in low light environmental conditions to enhance the brightness for the video or photo. In low light environmental conditions, the higher the ISO value, the brightness the captured video or photo, the greater the signal noise, grainy strong, and vice-versa.

It influences the brightness of the video or photo. When shooting in a contrasting light environmental conditions, you can adjust this parameter to control the brightness of the video or photo. Value adjustment will increase the brightness of the video or photo based on the default basis.

-2.0, -1.5, -1.0, -0.5, 0（Default）, +0.5, +1.0, +1.5, +2.0

Divided into two metering modes: spot and center.

Divided into high, medium and low grades.

High-density lithium polymer battery, battery specification is 3.85V, 1400/1430mAH(min/typ), 5.39/5.51Wh(min/typ), 8 hours standby. The sensor and ISP sleep in the low-power mode, a significant reduction in power consumption, up to 8 hours of standby time. The camera is ready to shoot video or photo in just 3 seconds from the off mode. The customized power management chip from Texas Instruments is designed to create minimum heat at working condition and enables quick radiation of heat. Continue recording for 110 min, but the camera will not overheat. Input Current: 1A Input Voltage: 5V.

The chart below indicates the approximate continuous recording time (hour:min) you can expect when shooting in various video modes using a fully charged battery.

It's easy to preview and play back of videos and photos on the LCD.
