Ambarella A12S SoC Allows For Cheaper 4K 30 fps Action Cameras, or Does it Not?

[Update: I’ve been informed that Ambarella A12S product brief from their website contains outdated information, and that A12S does indeed support 4K @ 30 fps, not only 2K @ 30 fps] [Update 2 (03/09/2016): The company has now updated the page, and I’ve myself updated the article accordingly] Some ultra cheap Allwinner V3 based cameras are advertised as 4K cameras, but in reality they are limited to 4K @ 15 fps, and on top of that the software have to extrapolate data to get to that resolution. So there are not usable for most people, unless maybe if you somehow need a 4K CCTV camera. Currently one of the cheapest “true” 4K action cameras is Yi Technology / Xiaomi Yi 2 sports camera based on Ambarella A9S SoC, capable of recording up to 4K @ 30 fps, and selling for around $250. But there’s now a new wave of cheaper “4K 30 fps cameras” based on Ambarella A12S75 Cortex A9 …

Xiaomi Yi 4K Action Camera 2 Offers an Alternative to GoPro HERO4 Black Camera

[Update: While Xiaomi is a minority investor of YI in China, and YI products are sold in Xiaomi stores, Xiaomi does not own YI Technology nor does it own, produce or design any of its products. Therefore any mentions of Xiaomi in the article should be read instead as “YI Technology.”] Xiaomi is about to launch a new 4K sports camera with Xiaomi Yi 4K powered by Ambarella A9SE dual core Cortex A9 processor and supporting video recording up to 4K @ 30 fps. The specs of the new camera is actually pretty similar to what you’ve got on GoPro HERO4 Black camera, plus some improvements as the comparison table below shows. I found the data on GeekBuying blog, so it could not be entirely unbiased, but it still gives an idea. Yi 4K Action Camera GoPro HERO4 Black Processor Ambarella A9SE Ambarella A9 Image Sensor Sony IMX377 12MP ½ 3” Sony IMX117 12MP ½ 3” Lens 7 glass, 155 …
