What is this yuv file?

The .yuv file extension is a color encoding scheme representation, which is made up of color blocks, that measure eight by eight pixels and used as a storage space for the encoding of both graphics, and video formats. The human eye is normally less sensitive when it comes to color, compared to light which accounts for fewer chrominance samples (U and V) for each occurrence of the luminance sample (Y). The file extension .yuv commonly falls under two distinct categories: the packed category, where the samples are compressed together to macropixels and stored in one array; and the planar format category, wherein every component is saved in a separate array with the final image resulting from the fusing of three distinct planes.The file extension .yuv is an actual representation of the encoded YUV image file that stores the respective color attributes for the brightness (represented by Y), and the chrominance (represented by the U and V) elements. The .yuv file extension is a more accurate color information storage format compared with the other popular format RGB, and is also used in relation to the representation of video files using the YUV format. In the context of video files, the file extension .yuv saves the sequences of the YUV image in one video file commonly using the 4:4:4, 4:2:2, and the 4:2:0 formats which can be interpreted by H.264 and MPEG-4 based decoders.The model represented by the file extension .yuv is an actual definition of the color space elements, in the context of composite color video standards like SECAM, PAL, and NTSC. The older black and white color systems only utilized the Y data, thus, requiring the incorporation of the U and V components to produce color pictures in normal black and white format for these types of receivers. The file extension .yuv also served as the foundation for digital video versions, which are the result of the derivatives formed from the axes of grey on blue/ yellow and red/ cyan, as well as the usage of blue and red luminance attributes.The YUV format supported by the file extension .yuv was primarily brought about by the desire of engineers to produce color television broadcast, using current black and white infrastructures of the time.

What is this yuv file?

Video file encoded in the YUV format; stores a sequence of YUV images as a single video file (see above description); may be saved in YUV 4:2:0, 4:2:2, 4:4:4 formats; some YUV video files may be decoded by MPEG-4 and H.264 decoders.
