::{{Par2| |clip| }}
:::Input clip.
:::PixelShiftRGB: all RGB(A) colorspaces are supported.
:::PixelShiftY(UV): all YUV(A) colorspaces are supported.
<br>
::{{Par2|RX, RY, GX, GY, BX, BY, AX, AY|float|0.0}}
::{{Par2|YX, YY, UX, UY, VX, VY, AX, AY|float|0.0}}
:::Specify the shift amount in each  (R, G, B, A) or (Y, U, V, A) plane.
:::*(X) horizontal shift: positive values shift left, negative values right.
:::* (Y) vertical shift: positive values shift upwards, negative values downwards.
:::Note that the shifting direction will be reversed if <code>Inverse=true</code>.
<br>
::{{Par2|Resizer|string|"Spline36"}}
:::Resizer to use to shift planes.
:::Available options: <code>"Bicubic", "Bilinear", "Blackman", "Gauss", "Lanczos", "Lanczos4", "Point", "Sinc", "Spline16", "Spline36", "Spline64"</code>.
:::Note that <code>"Point"</code> cannot do subpixel shifting because it uses only integer pixel coordinates, float values will be rounded.
<br>
::{{Par2|ChromaPixels|bool|false}}
:::By default, the X and Y shift values of the chroma planes are shifted in "luma pixels", meaning that the shift values are divided by the subsampling ratio of the input clip.
:::For example:
:::*YUV420, the X and Y shift values are divided by 2 since the chroma planes are half the width and height of the luma plane.
:::*YUV422 or YUV411, only the X shift value is divided by 2 and 4, respectively.
:::*YUV444, has no effect since the chroma planes are the same size as the luma.
:::When set to true, the X and Y shift values are not divided.
<br>
::{{Par2|Mode|int|1}}
:::Border mode:
:::* 0 : "fillmargins" - top and bottom borders are filled with a weighted average of its three neighbours from the previous line. Left and right borders are repeated, as in mode 1.
:::* 1 : "repeat" - fills the borders using the outermost line or column.
:::* 2 : "mirror" - fills the borders by mirroring.
:::* 3 : "reflect" - fills the borders by reflecting (whole sample symmetric).
:::* 4 : "wrap" - fills the borders by wrapping.
:::* 5 : "fade" - fills the borders to constant value.
:::* 6 : "fixborders" - A direction "aware" modification of FillMargins. It also works on all four sides.
:::Default: 1 (all other modes require the [[FillBorders]] plugin)
<br>
::{{Par2|Inverse|int|false}}
:::If true, it will reverse the shifting direction:
:::*(X) horizontal shift: negative values shift left, positive values right.
:::*(Y) vertical shift: negative values shift upwards, positive values downwards.
