16:9:
8,18 gb
16:48 lenght
width: 3840
hight: 2160
So 4:3 capture larger area (focal length are smaller), but don't use 4K.
16:9 take video with tiner area (focal length are smaller), and use 4K.
4K video as defined by Digital Cinema Initiatives has an aspect ratio of 256:135 close to 1.9:1. 4096 pixels x 2160 pixels.
If you want a higher pixel resolution 4:3 digital video, you can, though having a high resolution 4:3 pixel density doesn’t make practical sense, since ordinary 4:3 video as defined by NTSC has 640 pixels x 480 pixels.
Think of aspect ratio this way: 4” wide by 3” high or any multiple of that ratio such as 8”x6”, 16”x12”, 40”x30”, or with pixels: 640 pixels wide x 480 pixels high, 320 pixels x 240 pixels. The higher the pixel count, the higher the resolution, even 4000 pixels x 3000 pixels. In my opinion, for your 4:3 video to be most compatible with as many viewers as possible on as many devices, 4:3 should be 640 pixels x 480 pixels.
