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
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
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:
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
import { staticFile } from "remotion";
const duration = await getVideoDuration(staticFile("video.mp4"));
