There's no practical difference between YUV and YCbCr: sort of more like "RGB" and "BGR".

    99- RGB distinguishes color pixel values into 3 components: Red, Green, Blue. (hence the name)
    1010- YUV uses a different representation schema that represents color pixel values in: Luma (Y, or brightness), Chroma (U and V, two color differences). This format exploits the fact that humans are able to better notice details in luminance (approximated by luma) than in chroma. ^(Note: YUV represents color in 3 components)^

    13 '''Note:''' The term "YUV" is ambiguous and often used wrongly, including the definition of pixel formats in FFmpeg. A more accurate term for how color is stored in digital video would be [https://en.wikipedia.org/wiki/YCbCr YCbCr]. Y'UV on other other hand specifies a colorspace consisting of luma (Y') and chrominance (UV) components. For more info read [https://en.wikipedia.org/wiki/YUV the respective Wikipedia article]. In the following, the term YUV is used as in the FFmpeg pixel formats, referring to YCbCr in digital video.
