Use 2D Transform to apply basic axis transformations and camera shake effects to clips.
To access the 2D Transform menu, use:
Batch, then select a node from the Node bin.
Timeline, then use Batch FX (see Creating Batch FX).
Timeline, then add Timeline FX from the Effects ribbon (see Adding Timeline FX).

This node accepts a front and a matte clip, and outputs a result and an outmatte.
