The Xiaomi Yi 4k+ Camera announced today at CES is revolutionary just barely by it’s 4k 60fps spec which is ahead of all other action cameras in the market. However 1080p and 720p resolutions have not seen a bump in frame rates with the cameras still doing the same specs as last year’s Yi 4k camera which is in turn the same spec as the GoPro Hero 4, 5 and Sony X3000 Action cameras.
The YI 4K+ uses the newest Amba H2 SOC, the first 14nm video processing/encoding SOC part which is quite fast and on the spec list fast enough for 120fps at 4k on AVCHD encode. This pixel rate is fast enough for 240fps at full 1080p or 480fps at 720p without maxing the system. Yi 4k+ however has remained conservative due to hardware limitations in other areas like imaging sensor and memory allocation to just 4k 60p recording.[...]
