effect

Select Effect Layer. Selects an effect layer and starts a new layer segment in the request string, which is associated with the current layer.

effect= *n*

All commands within the new segment are applied to the specified effect layer. An effect layer segment is terminated by the next layer= or effect= command or by the end of the request.

n must be less than 0 for outer layer effects (i.e. effects behind the parent layer) and greater than 0 for inner layer effects (i.e. effects within the parent layer). Effect layer numbers do not have to be consecutive.

The effect layer number specifies the z-order, in case of multiple effect layers for the same parent layer. Higher-numbered layers are placed on top of lower-numbered layers.

Effect layers may be attached to layer=comp.

Properties
