Video quality

HiSilicon HI3559 and Panasonic MN34120 advanced image chipsets enable recording videos in up to 4K or lower resolution. There is also a 170-degree wide angle lens and this hardware setup guarantee excellent image quality that can record even the tiniest details. Playing 4K movies recorded by REXSO Explorer K will make you feel like you are there again!

Files are encoded here with new, lossless H.265 codec that makes it smaller by 50% compared to the previous H.264 codec, and thus videos will take up much less space on MicroSD card. It’s worth mentioning that 4K movies are saved at 30 frames per second, and 60 fps mode are only available in 1080p resolution.

Six-axis stabilization ensures smooth recordings, which is especially important when making videos from high-speed sports activities like mountain biking, high diving and downhill skiing. Stabilization is achieved through a three-axis gyroscope and a three-axis accelerometer that respond in real-time to camera position movements and constantly take them into account in the image processing. This software stabilization also allows you to record perfect time lapse and slow motion videos.

Accessories and operation

2 inch display acts as camera user interface. Operation has been simplified and there is only one external button which can be pressed to start and stop recording. Scuba diving videos can be shot thanks to a rugged waterproof casing that protects the camera from water and dust.

Fast WiFi connection is a smart solution that makes it easy to transfer large video files to computer or smartphone and enables the camera to be controlled by a smartphone with a dedicated Android or iOS application. Files can be stored on a 16 to 64 GB MicroSD card (sold separately). Take note, that you should use memory card that has a correspondingly high speed class, at least U3, to allow smooth 4K video recording. Slower cards won’t keep up with power needed to process big files, which could result in lost frames and bad movie quality. 1200 mAh battery is typical for cameras of this class and when fully charged, it can work up to 90 minutes.
