Usage
usage.tsx
import CropperVideoDemo from "@/registry/examples/cropper-video-demo";export default function Example() { return <CropperVideoDemo />;}- Use as a reference for cropping uploaded or remote video content.
- Use when demonstrating controlled crop coordinates and zoom state.
- Use when a fixed 16:9 output frame and visual crop grid are needed.
- Use as a starting point for adding video playback controls around a cropper.
Examples
Contained demo
Render the demo inside a constrained content column.
contained-demo.tsx
import CropperVideoDemo from "@/registry/examples/cropper-video-demo";export default function VideoCropPage() { return ( <main className="mx-auto w-full max-w-3xl p-6"> <CropperVideoDemo /> </main> );}Full-height workspace
Give the demo a larger responsive workspace.
full-height-workspace.tsx
import CropperVideoDemo from "@/registry/examples/cropper-video-demo";export default function VideoEditor() { return ( <section className="min-h-screen bg-muted/30 p-4 md:p-8"> <div className="mx-auto h-full max-w-5xl"> <CropperVideoDemo /> </div> </section> );}Card presentation
Present the cropper as part of an editor card.
card-presentation.tsx
import CropperVideoDemo from "@/registry/examples/cropper-video-demo";export default function VideoCropCard() { return ( <div className="rounded-xl border bg-card p-4 shadow-sm"> <CropperVideoDemo /> </div> );}Accessibility
- The playback control is a native button with visible Pause and Play text, so its purpose is available without relying on the icons.
- The demo does not provide captions, a transcript, or alternative content for the remote video; add a caption track or equivalent accessible description for production media.
- The video has no native controls in this demo. Provide an accessible playback interface if users need more than the included play/pause action.
- Ensure the cropper's drag and zoom interactions have an equivalent keyboard-accessible workflow when used in an end-user editor.
- The remote video is loaded with crossOrigin="anonymous"; ensure the host permits the required cross-origin access in production.
