Measured entry

magicui-hero-video-dialog

hero-effect3dmotion on file

A client-side React thumbnail that opens an embedded video in an animated full-screen overlay. It ships as a shadcn registry component and relies on Tailwind utility classes, the shared cn helper, Motion for transitions, and Lucide for its play and close icons.

Verdict

A solid visual starting point that built, mounted, and stayed within its tested viewports. It needs a shadcn-style setup, and teams with strict modal accessibility requirements should add proper dialog behavior and focus management before shipping.

Use it if

  • You need a hero thumbnail that launches an iframe video without navigating away.
  • Your app already uses shadcn conventions, Tailwind utilities, Motion, and Lucide icons.
  • You want selectable entrance and exit directions without designing the animation states yourself.

Skip it if

  • You need full dialog semantics, focus trapping, focus restoration, or background scroll locking out of the box.
  • You want a native video element rather than content hosted in an iframe.
  • You are minimizing animation and icon dependencies for a single video trigger.

In a non-shadcn project, add Tailwind with the expected theme tokens, Motion, Lucide React, and a compatible cn class-merging helper. Configure the source alias or replace that import, mark the component for client rendering where required, and supply permitted thumbnail and iframe URLs.
