===
This effect is used for YUV input video from older cameras using 3 sensors. It is possible to have misalignment of the 3 sets of numbers: Y, which represents the luminance or brightness component, and for U and V representing the chrominance (color) components. If they were misaligned in the video, you can use YUVShift to realign. To move a specific component up/down, modify the dy value using the slider bar in the RGBShift window.

I think here specifically it must say YUVShift?
