the clips (and perhaps even other layers) contained within and the “bounding box” that
represents the nest in the Motion canvas is drawn on the fly. Nested comps in After
Effects do have a size, however, and Pro Import AE needs to calculate what that is.
Pro Import AE considers Position and Scale when it calculates what the size of the
nested comp needs to be.
In the following example, three clips of a ski jumper are nested into a layer and the layer
is scaled so the three clips appear on screen together. This creates a nest in After
Effects for the three jumpers.
You can see above that the nested composition is created at such a size so that you
see all three jumper layers.
Other parameters in Motion can affect the size the size of the bounding box, but that
wonʼt affect the size of the nested comp in After Effects. Rotation is a good example.
