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.

Found one. The Sony DSC-RX10 can output uncompressed 4:2:2 video over HDMI.

GH4 is the first on my wishlist, Brad.

The Panasonic GH4 offers 4:2:2 but maybe only on the external output to an external recorder?

Welcome! Even Nikon D7100 has 4:2:0. Maybe my D90 is the only one with 4:2:2 ?!

16 bpp is better than 12 bpp. This tell more about the quality of the camera than what will you shoot with it.

Yes, 4:2:2 is better than 4:2:0. The bigger the numbers the better the encoding. But, your explanation is a bit misleading and I recommend people to read:

Chroma Subsampling on Wikipedia

This is worth taking care mostly when you shoot green screen, else is not that much important.

Nikon D5100 also bad, 4:2:0.
Will have to test some better and new Nikon cameras, like D600 or even D7100/D5200/D5300.

You're right, a good concept is better than a top machine. You have 3 usefuls now, lol.

My d90 has 4.2.2 but it is not full HD. I think that a good concept video is better than my abstract theory. Buyers use mobile phones to get our product, they miss a lot of colors... :) Thanks for useful, I think you are the only one.

Just checked mine and is Planar 4:2:0 Yuv full scale. Its a Nikon D3100. Ouch!

Checked my brother camera an is also the same. He has a Canon EOS 650D.

So I guess an even higher price camera could have that other 4:2:2 Yuv ?

Good to know though, thank you Your Highness the King!
