About video codecs YUV 4.2.0 v. 4.2.2
Hi. Do you want to start selling video footage and don't know what camera to buy? Forget about prices, check this first! Take a SD Card with you and ask seller to let you shoot a small video. Come home and check video codec (use VLC for this, Tools - Codec information).
You will see something like Planar 4:2:0 YUV or Planar 4:2:2 YUV.
What this means?
Short explanation: 4:2:2 is better than 4:2:0. So, that camera is the winner.
Long explanation: 4:2:0 format requires 4*8+8+8=48 bits for 4 pixels, so its color depth is 12 bits per pixel.
For 4:2:2, depth is 4*8+2*8+2*8 = 64 bits per 4 pixels, so 16 bits per pixel.
YUV is the name of the color space that is common to all "YUV" pixel formats. YUV colors are represented with one "luminance" component called Y (equivalent to grey scale) and two "chrominance" components, called U (blue projection) and V (red projection) respectively.
Hope this help. King out.
