If you are using an RGB color space, you will want to use the \textit{RGBShift} effect instead. Figure~\ref{fig:yuvshift} (top) shows the blue \textit{U} component aligned too far to the right/down. And the red \textit{V} component is misaligned too far to the right/down. Note the \textit{U\_dx} current slider bar set to $0$ as shown by the input box value in the YUVShift plugin window. All components are currently at zero. A corrected video image is shown in the bottom. Now the red and blue colors are correctly aligned. Note how \textit{U\_dx} is now at $+26$ and \textit{V\_dx} is now $+41$ to realign the image.
