A zoom on a clip
A zoom effect applied to the clip's screen layer (does not affect the camera). Use manualZoom with a focusPoint, or trackingZoom to follow the cursor automatically. Times are in ms on the clip's playback timeline (cuts applied). Internally the zoom stays anchored to the footage, so it doesn't drift when cuts change later.
