The king of panoramic action cameras, Insta360, has launched its new flagship X4. CT takes this camera, which boasts 8K high resolution and AI technology, straight to Wuling and the Mount Fuji hill climb race in Japan for extreme testing! After unboxing and detailing the key upgrades to the body, the camera is immediately mounted on a road bike for real-world verification. The footage showcases 8K fine detail, AI auto color grading, and the new flat single-lens mode, while also testing AI audio noise reduction in strong winds during long descents. Additionally, it demonstrates how to combine GPS data from a bike computer to export cool dashboard videos with one tap.
