Body
Update an existing overlay
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.

0 < x <= 9007199254740991Top-left corner of the overlay, as a percentage of the video canvas (0-100). Relative so the anchor survives video aspect ratio changes.

Start time. Milliseconds on the clip playback timeline (with cuts applied) — the same timeline as the cut transcript.
0 <= x <= 9007199254740991Intro/outro animation: smooth fades the overlay in at its start and out at its end, hard_cut pops it in and out.
