.YUV File Extension

Image created in the YUV format, which splits color across Y, U, and V components; stores the brightness (luminance) as the Y value, and the color (chrominance) as U and V values; can be used for storing color information more accurately than the direct RGB representation.

The YUV format is often written Y'UV.

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.
