The Offset effect pans the image within a layer. Visual information pushed off one side of the image appears on the opposite side. One use of the Offset effect is to create a looping background from a layer. At Best quality, the offset is performed with subpixel precision.

Lloyd Alvarez provides a simple expression for the Offset effect to simulate a poorly timed film projector: www.adobe.com/go/learn_ae_lloydoffsetprojector.

Shift Center To

The new position of the original image’s center point.

Blend With Original

The effect’s transparency. The result of the effect is blended with the original image, with the effect result composited on top. The higher you set this value, the less the effect affects the layer. For example, if you set this value to 100%, the effect has no visible result on the layer; if you set this value to 0%, the original image doesn’t show through.

This effect works with 8-bpc and 16-bpc color.
