video-overlay

Composite a graphic onto video — text, a logo/image, a static transparent PNG, or an animated effect — and place it accurately, including locking it to a moving subject (a face, eye, hand, object). Use whenever the user wants to add/overlay/burn-in/stick something onto footage, place a watermark or label, or position a graphic precisely. Covers transparency (RGBA), animated overlays, timed windows, and coordinate-finding.
