&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;PIX_FMT_YUV420P contains three channels (or components):&lt;br /&gt;
* Y' ([[luminance]]) channel&lt;br /&gt;
* Cb ([[chrominance]] blue) channel&lt;br /&gt;
* Cr ([[chrominance]] red) channel.&lt;br /&gt;
&lt;br /&gt;
The [[chrominance]] is [[subsampled]] using the '''420''' scheme:&lt;br /&gt;
&lt;br /&gt;
 Note: Be careful not to confuse this pixel format with [[PIX_FMT_YUVJ420P]].&lt;br /&gt;
&lt;br /&gt;
YCbCr 4:2:0 indicates a planar [[YCbCr]] colorspace where a 2x2 block of pixels in an image is represented by 4 Y samples, 1 for each pixel, but all 4 pixels share a Cb sample and a Cr sample.&lt;br /&gt;
&lt;br /&gt;
 Note: The '''P''' in YUV420P indicates '''[[planar]]''' not [[progressive]] or [[palette]] or [[packed]].&lt;br /&gt;
&lt;br /&gt;
It has the following characteristics:&lt;br /&gt;
* YUV colorspace.&lt;br /&gt;
* 12bits per pixel '''average'''.&lt;br /&gt;
