Fields

Name Description
Cmyk

CMYK colorspace (cyan, magenta, yellow, and key black) intended for printing.

Note: Not supported by the encoder.
Luminance

Single channel, luminance.
Rgb

The pixel data will be preserved as RGB without any sub sampling.
YCbCrRatio410

YCbCr (luminance, blue chroma, red chroma) color as defined in the ITU-T T.871 specification. This ratio uses half of the vertical and one-fourth the horizontal color resolutions.

Note: Not supported by the encoder.
YCbCrRatio411

YCbCr (luminance, blue chroma, red chroma) color as defined in the ITU-T T.871 specification. In 4:1:1 chroma subsampling, the horizontal color resolution is quartered.

Note: Not supported by the encoder.
YCbCrRatio420

YCbCr (luminance, blue chroma, red chroma) color as defined in the ITU-T T.871 specification. Medium Quality - The horizontal sampling is halved and the Cb and Cr channels are only sampled on each alternate line.
YCbCrRatio422

YCbCr (luminance, blue chroma, red chroma) color as defined in the ITU-T T.871 specification. The two chroma components are sampled at half the horizontal sample rate of luma while vertically it has full resolution.

Note: Not supported by the encoder.
YCbCrRatio444

YCbCr (luminance, blue chroma, red chroma) color as defined in the ITU-T T.871 specification. High Quality - Each of the three Y'CbCr components have the same sample rate, thus there is no chroma subsampling.
