    Video showing side-by-side comparison of 4K-recording capable (or claimed as capable) action cams based on different SoCs.

    Hardware tested (4k footage specs). No brands or models here:

    Ambarella A12 action camera (3840x2160p30, h264, 60Mbps),
    Novatek NT96660 based cam (2880x2160p24, h264, 32Mbps),
    Allwinner V3 powered device (3200x1800p30, h264, 26Mbps),
    Sunplus SPCA6350 cam (3840x2160p25, MJPEG, 60Mbps).

    Framerates were aligned to 29.97. Videos were cropped without resizing or any other filters and combined into side-by-side layout. Resulting video was encoded with h265 codec (HEVC) at ~80Mbps bitrate, so your PC should be powerful enough to play it without lags (I suggest to use MPC or VLC video player).

    Looks like ambarella and v3 both lift the shadows, novatek exposes like I have the V3 set up to do now. Does A12 have real 30fps?

      Yes, A12 records 4k30 with no tricks like frame skipping. It also can do 2.7k60 and [email protected]

      By the way A12 and V3 cams I tested here share kinda similar BSI sensors from Sony.

        A12 also shows the least sharpening. NTK and v3 you can tell its cranked up. Even better that A12 can be edited like allwinner for even higher quality. I can probably match it 90% at 2k in good lighting but a do-over would have me buying the A12.

          I'm pretty sure if A12 firmware could be tuned to have more details in highlights (autoknee and EV corrections) and shadows (moderate WDR/HDR) it would compete any Ambarella A9 or any other actual 4k h264 SoC solution.

            EIS (1080p60 ) CAMparison. Gyro-enabled A12 vs NT96660 side by side.



            Note: Both cams were equipped with same lenses.

              hia, thanks muchly for the high quality encode. had to use frame by frame or 0.1 speed cus it didnt play back smoothly on this hardware . frame by frame worked well for comparing the cams though. very informative it was for me.

              a suggestion would be to use MKV for the container next time. avi only really works with wav,mp3,mpeg4. Matroska (.mkv) is a lot more flexible and is a open standard + good wide support.

              I transferred the video into a mkv container, see the links.
              no re-encoding was done but it fixed it. so it now plays back in mpv too
              I used the command:
              Code:
              ffmpeg -c:v hevc -i '~/Downloads/Action Cams/camparison-4k-part1.avi' -c copy '~/Downloads/Action Cams/camparison-4k-part1.mkv'
              other download link, should be around for a long time due to no expire time.
