+# Getting video duration with Mediabunny
+
+Mediabunny can extract the duration of a video file. It works in browser, Node.js, and Bun environments.
+
+## Getting video duration
+
+```tsx
+import { Input, ALL_FORMATS, UrlSource } from "mediabunny";
+
+export const getVideoDuration = async (src: string) => {
+  const input = new Input({
+    formats: ALL_FORMATS,
+    source: new UrlSource(src, {
+      getRetryDelay: () => null,
+    }),
+  });
+
+  const durationInSeconds = await input.computeDuration();
+  return durationInSeconds;
+};
+```
+
+## Usage
+
+```tsx
+const duration = await getVideoDuration("https://remotion.media/video.mp4");
+console.log(duration); // e.g. 10.5 (seconds)
+```
+
+## Using with local files
+
+For local files, use `FileSource` instead of `UrlSource`:
+
+```tsx
+import { Input, ALL_FORMATS, FileSource } from "mediabunny";
+
+const input = new Input({
+  formats: ALL_FORMATS,
+  source: new FileSource(file), // File object from input or drag-drop
+});
+
+const durationInSeconds = await input.computeDuration();
+```
+
+## Using with staticFile in Remotion
+
+```tsx
+import { staticFile } from "remotion";
+
+const duration = await getVideoDuration(staticFile("video.mp4"));
+```
