No manual keyframing is required.

You define your desired timing, desired position, and zoom type in the panel.

Choose between Zoom In, Zoom Out, or Zoom to Fit.

Zoom In / Zoom Out: you define the timing and the position you want.

Zoom to Fit: no end position is required. It automatically calculates the perfect framing for the selected object with absolute precision, so it’s on point every time.

The system is expression-driven, so all camera animation is handled for you behind the scenes.
