ImageRGBToYUV - ComfyUI Built-in Node Documentation - ComfyUI

The ImageRGBToYUV node converts an RGB image into YUV-style color components using an RGB-to-YCbCr color conversion. It splits the result into three separate images — Y (luminance, or brightness), U (blue-difference chroma), and V (red-difference chroma) — and returns each component at the same width and height as the input.

Inputs

Parameter	Description	Data Type	Required	Range
`image`	The input RGB image to convert into Y, U, and V components. If the image contains an alpha channel, only the first three (RGB) channels are used.	IMAGE	Yes	-

Outputs

Output Name	Description	Data Type
`Y`	The luminance (brightness) component of the YUV color space, returned as a three-channel image	IMAGE
`U`	The blue-difference chroma component of the YUV color space, returned as a three-channel image	IMAGE
`V`	The red-difference chroma component of the YUV color space, returned as a three-channel image	IMAGE

Each output has the same width and height as the input image. The corresponding Y, U, or V component is repeated across all three channels so that every output is returned as a standard three-channel image.
