}Auto-generate zooms from mouse activity
Generates tracking zooms from the mouse clicks in the clip’s screen recording — the API twin of the editor’s “Generate zooms”. Every click opens a zoom window; nearby windows are merged. Requires the clip to contain a screen recording; returns an empty list when it has no usable mouse clicks.

Clip identifier
"cl_xyz789ghi012"
Body
Automatically generate tracking zooms from the mouse clicks in the clip's screen recording — the API twin of the editor's "Generate zooms". Warning: by default this replaces the clip's existing tracking zooms (see replaceExisting).
How aggressively to zoom. slow opens fewer, longer windows; fast opens shorter, tighter ones at a higher scale. Defaults to medium.
slow, medium, fast "medium"
Defaults to true: the clip's existing tracking zooms are REMOVED before the generated ones are added, so repeated calls regenerate instead of stacking. Pass false to keep existing tracking zooms. Manual zooms are never touched.
true
Override the magnification factor (1 = no zoom, 3.5 = max). Defaults to the intensity preset's scale (1.5 for slow/medium, 2 for fast).
1 <= x <= 3.51.5
Response
OK
Zooms generated from the clip's mouse activity
The generated tracking zooms, in ms on the clip's playback timeline (cuts applied). Empty when the screen recording has no usable mouse clicks.
Hide child attributes
Hide child attributes
Duration in ms of playback. 0 when the zoom's footage is entirely cut out.
x >= 02000
Zoom ID
"ef_abc123"
Start time in ms on the clip's playback timeline (cuts applied)
x >= 01000
manualZoom zooms into a fixed focusPoint on the screen. trackingZoom automatically follows the cursor in the screen recording.
manualZoom, trackingZoom "manualZoom"
Point on the zoomed footage to zoom into, expressed as percentages of its dimensions. Required for manualZoom; ignored for trackingZoom.
Magnification factor (1 = no zoom, 3.5 = max).
1 <= x <= 3.52
