Template Element

1. Shape

interface TemplateClip extends BaseClip {
  type: "template";
  template: string;
  variant?: string;
  version?: string;
  data: Record<string, unknown>;
  overrides?: {
    data?: Record<string, unknown>;
    style?: Style;
    transition?: Transition;
    zIndexOffset?: number;
  };
}

2. Supported template names

Current documented names:

• product-intro
• slideshow
• subtitle-video
• talking-head
• comparison
• countdown
• text-reveal
• news
• quote
• list

3. Runtime boundary

template clips expand into normal clips at runtime. The exact generated structure depends on the selected template and its data.

Template-level inheritance of transform, style, animations, keyframes, or transition is not documented as a stable child-clip behavior.

Use variant to select registered defaults for a template. Use overrides to merge final data, apply style to generated non-audio clips, add a default transition, or offset generated zIndex values.
