Slots & Motion Tracking

How text slots function with animated bounding box motion tracking.

Slot Structure

Each slot contains localized text content in multiple languages, optional styling, and optional tracking data for animations.

Motion Tracking Data

Tracking data is represented as an array of keyframes, each defining a quadrilateral bounding box at a specific timestamp. The video player linearly interpolates between adjacent keyframes to render smooth overlays.

See the OVM Metadata Schema for detailed field definitions.
