depth

enum<string>

Where the overlay sits relative to the presenter: the person in the clip's camera recording, or in its uploaded footage when the clip has no camera. front paints over everything. behind_presenter paints it behind the person but over everything else: in any layout the person is matted out of their footage and redrawn above the overlay. Fullscreen and framed layouts keep the recorded room around them; a cut-out layout replaces the room with the clip background. New overlays start on front. Without a presenter the overlay paints in front either way.

Available options:

front,

behind_presenter

Example:

"behind_presenter"

dimensions

object

Overlay size in artboard pixels. Absolute (not a percentage) so the overlay shape never distorts when the artboard dimensions change. Both sides must be greater than 0 — the renderer lays the overlay out into this box, so a zero or negative side has no valid meaning.

point

Top-left corner of the overlay, as a percentage of the video canvas (0-100). Relative so the anchor survives video aspect ratio changes.

Example:

30

point.yPct

number

required

Example:

startTimeMs

integer

Start time. Milliseconds on the clip playback timeline (with cuts applied) — the same timeline as the cut transcript.

Required range: 0 <= x <= 9007199254740991

transition

enum<string>

Intro/outro animation: smooth fades the overlay in at its start and out at its end, hard_cut pops it in and out. An animation replaces it while set; setting transition without animation removes the animation.

Available options:

smooth,

hard_cut

Example:

"smooth"

zIndex

integer

Stacking position among the clip's image, video and text overlays: 0 is the backmost. depth applies first — a behind_presenter overlay stays behind the presenter whatever its zIndex — so the order only matters among overlays at the same depth. Lottie overlays share the stack but aren't listed, so listed values can skip a number. A value past the top moves the overlay to the front; the other overlays keep their relative order.

Required range: 0 <= x <= 9007199254740991

Example:

0
