next-video

Next video is a react component for adding video to your next.js application. It extends both the <video> element and your Next app with features for automatic video optimization.

• Smart storage: Store large video files outside of your git repo
• Auto optimized: Optimize video files and deliver via CDN for better playback performance and quality
• Customizable UI: Choose from themes or build your own player controls
• Posters & Previews: Zero-config placeholder images and timeline hover thumbnails
• Wider compatibility: Use videos that aren’t supported natively by all browsers
• Analytics built-in (optional): See how often videos get watched and track video performance
• AI-powered: Add auto-generated captions to your videos and use transcripts

import Video from 'next-video';
import getStarted from '/videos/get-started.mp4';

export default function Page() {
  return <Video src={getStarted} />;
}

Setup

Automatic Setup

In the root of your Next.js project, run:

npx -y next-video init

This will (with prompting):

• install next-video as a dependency
• update your next.config.js file
• if you're using TypeScript, add types for your video file imports
• create a /videos directory in your project which is where you will put all video source files.

It will also update your .gitignore file to ignore video files in the /videos directory. Videos, particularly any of reasonable size, shouldn't be stored/tracked by git. Alternatively, if you'd like to store the original files you can remove the added gitignore lines and install git-lfs.

Remote storage and optimization

Vercel recommends using a dedicated content platform for video because video files are large and can lead to excessive bandwidth usage. By default, next-video uses Mux (a video API for developers), which is built by the the creators of Video.js, powers popular streaming apps like Patreon, and whose video performance monitoring is used on the largest live events in the world.

• Sign up for Mux
• Create an access token
• Add environment variables to .env.local (or however you export local env variables)

# .env.local
MUX_TOKEN_ID=[YOUR_TOKEN_ID]
MUX_TOKEN_SECRET=[YOUR_TOKEN_SECRET]

Manual Setup

Install the package

cd your-next-app

# If your project is using NPM (the default for Next.js)
npm install next-video

# If your project is using Yarn
yarn add next-video

# If your project is using pnpm
pnpm add next-video

Add Next Video to your Next.js config

next.config.js

If you're using CommonJS modules:

const { withNextVideo } = require('next-video/process');

/** @type {import('next').NextConfig} */
const nextConfig = {}; // Your current Next Config object

module.exports = withNextVideo(nextConfig);

next.config.mjs

If you're using ES modules:

import { withNextVideo } from 'next-video/process';

/** @type {import('next').NextConfig} */
const nextConfig = {};

export default withNextVideo(nextConfig);

Add video import types to tsconfig.json

This is only required if you're using TypeScript, and makes sure your video file imports don't yell at you for missing types. video.d.ts should have been created in your project root when you ran npx next-video init, if not you can create it manually:

// video.d.ts
/// <reference types="next-video/video-types/global" />

Then add that file to the include array in tsconfig.json.

{
  // ...
  "include": ["video.d.ts", "next-env.d.ts", /* ... */ ]
  // ...
}

Usage

Local videos (Demo)

Add videos locally to the /videos directory then run npx next-video sync. The videos will be automatically uploaded to remote storage and optimized. You'll notice /videos/[file-name].json files are also created. These are used to map your local video files to the new, remote-hosted video assets. These json files must be checked into git.

npx next-video sync

You can also add next-video sync -w to the dev script to automatically sync videos as they're added to /videos while the dev server is running.

// package.json
"scripts": {
  "dev": "next dev & npx next-video sync -w",
},

Now you can use the <Video> component in your application. Let's say you've added a file called awesome-video.mp4 to /videos

import Video from 'next-video';
import awesomeVideo from '/videos/awesome-video.mp4';

export default function Page() {
  return <Video src={awesomeVideo} />;
}

While a video is being uploaded and processed, <Video> will attempt to play the local file. This only happens during local development because the local file is never uploaded to your git repo.

Remote videos

For videos that are already hosted remotely (for example on AWS S3), import the remote URL and refresh the page. This creates a local JSON file in the /videos folder and the sync script will start uploading the video.

import Video from 'next-video';
import awesomeVideo from 'https://www.mydomain.com/remote-video.mp4';

export default function Page() {
  return <Video src={awesomeVideo} />;
}

If the hosted video is a single file like an MP4, the file will be automatically optimized for better deliverability and compatibility.

Remote videos with string source URL

In some cases you might not have the remote video URL's available at the time of import.

That can be solved by creating a new API endpoint in your Next.js app for /api/video with the following code.

App router (Next.js >=13)

// app/api/video/route.js
export { GET } from 'next-video/request-handler';

Pages router (Next.js)

// pages/api/video/[[...handler]].js
export { default } from 'next-video/request-handler';

Then set the src attribute to the URL of the remote video, refresh the page and the video will start processing.

import Video from 'next-video';

export default function Page() {
  return <Video src="https://www.mydomain.com/remote-video.mp4" />;
}

Player only (Demo)

Since v1.1.0 you can import the player component directly and use it without any upload and processing features.

import Player from 'next-video/player';
// or
import BackgroundPlayer from 'next-video/background-player';

export default function Page() {
  return <Player
    src="https://www.mydomain.com/remote-video.mp4"
    poster="https://www.mydomain.com/remote-poster.webp"
    blurDataURL="data:image/webp;base64,UklGRlA..."
  />;
}

Custom poster and blurDataURL

You can add a custom poster and blurDataURL to the video by passing them as props.

import Video from 'next-video';
import awesomeVideo from '/videos/awesome-video.mp4';
import awesomePoster from '../public/images/awesome-poster.jpg';

export default function Page() {
  return <Video 
    src={awesomeVideo} 
    poster={awesomePoster.src} 
    blurDataURL={awesomePoster.blurDataURL} 
  />;
}

This is a good solution but it will not provide the same level of optimization as the automatic poster and blurDataURL by the default provider.

To get the same level of optimization you can use a slotted poster element.

Slotted poster image element (Demo)

Add a slotted poster image element (like next/image) to the video by passing it as a child with a slot="poster" attribute.

Now your image will get all the benefits of the used image component and it will be nicely placed behind the video player controls.

import Image from 'next/image';
import Video from 'next-video';
import awesomeVideo from '/videos/awesome-video.mp4';
import awesomePoster from '../public/images/awesome-poster.jpg';

export default function Page() {
  return (
    <Video src={awesomeVideo}>
      <Image 
        slot="poster" 
        src={awesomePoster}
        placeholder="blur"
        alt="Some peeps doing something awesome"
      />
    </Video>
  );
}

Custom Player (Demo)

You can customize the player by passing a custom player component to the as prop.
The custom player component accepts the following props:

• asset: The asset that is processed, contains useful asset metadata and upload status.
• src: A string video source URL if the asset is ready.
• poster: A string image source URL if the asset is ready.
• blurDataURL: A string base64 image source URL that can be used as a placeholder.

import Video from 'next-video';
import ReactPlayer from './player';
import awesomeVideo from '/videos/awesome-video.mp4';

export default function Page() {
  return <Video as={ReactPlayer} src={awesomeVideo} />;
}

// player.tsx
'use client';

import type { PlayerProps } from 'next-video';
import ReactPlayer from 'react-player';

export default function Player(props: PlayerProps) {
  let { asset, src, poster, blurDataURL, thumbnailTime, ...rest } = props;
  let config = { file: { attributes: { poster } } };

  return <ReactPlayer
    url={src}
    config={config}
    width="100%"
    height="100%"
    {...rest}
  />;
}

Background Video (Demo)

You can use a <BackgroundVideo> component to add a video as a background with no player controls. This saves about 50% of the JS player size and is optimized for background video usage.

The <BackgroundVideo> component is a custom player like you saw in the previous section.

The thumbnailTime query parameter in the example below is used to generate a poster image and blur up image at the specified time in the video (limited to usage with the mux provider).

import BackgroundVideo from 'next-video/background-video';
import getStarted from '/videos/country-clouds.mp4?thumbnailTime=0';

export default function Page() {
  return (
    <BackgroundVideo src={getStarted}>
      <h1>next-video</h1>
      <p>
        A React component for adding video to your Next.js application.
        It extends both the video element and your Next app with features
        for automatic video optimization.
      </p>
    </BackgroundVideo>
  );
}

Hosting & Processing Providers

You can choose between different providers for video processing and hosting. The default provider is Mux. To change the provider you can add a provider option in the next-video config. Some providers require additional configuration which can be passed in the providerConfig property.

// next.config.js
const { withNextVideo } = require('next-video/process');

/** @type {import('next').NextConfig} */
const nextConfig = {};

module.exports = withNextVideo(nextConfig, {
  provider: 'backblaze',
  providerConfig: {
    backblaze: { endpoint: 'https://s3.us-west-000.backblazeb2.com' }
  }
});

Supported providers with their required environment variables:

Asset metadata storage hooks (callbacks)

By default the asset metadata is stored in a JSON file in the /videos directory. If you want to store the metadata in a database or elsewhere you can customize the storage hooks in a separate next-video config file.

The below example config shows the default storage hooks for the JSON file storage.

These hooks can be customized to fit your needs by changing the body of the loadAsset, saveAsset, and updateAsset functions.

// next-video.mjs
import { NextVideo } from 'next-video/process';
import path from 'node:path';
import { mkdir, readFile, writeFile } from 'node:fs/promises';

export const { GET, POST, handler, withNextVideo } = NextVideo({
  // Other next-video config options should be added here if using a next-video config file. 
  // folder: 'videos',
  // path: '/api/video',

  loadAsset: async function (assetPath) {
    const file = await readFile(assetPath);
    const asset = JSON.parse(file.toString());
    return asset;
  },
  saveAsset: async function (assetPath, asset) {
    try {
      await mkdir(path.dirname(assetPath), { recursive: true });
      await writeFile(assetPath, JSON.stringify(asset), {
        flag: 'wx',
      });
    } catch (err) {
      if (err.code === 'EEXIST') {
        // The file already exists, and that's ok in this case. Ignore the error.
        return;
      }
      throw err;
    }
  },
  updateAsset: async function (assetPath, asset) {
    await writeFile(assetPath, JSON.stringify(asset));
  }
});

Then import the withNextVideo function in your next.config.mjs file.

// next.config.mjs
import { withNextVideo } from './next-video.mjs';

/** @type {import('next').NextConfig} */
const nextConfig = {};

export default withNextVideo(nextConfig);

Lastly import the GET and POST, or handler functions in your API routes as you see fit. The handlers expect a url query or body parameter with the video source URL.

These are the most minimal examples for the handlers, typically you would add more error handling and validation, authentication and authorization.

App router (Next.js >=13)

// app/api/video/route.js
export { GET, POST } from '@/next-video';

Pages router (Next.js)

// pages/api/video/[[...handler]].js
export { handler as default } from '@/next-video';

Required Permissions for Amazon S3

If you're using Amazon S3 as the provider, you'll need to create a new IAM user with the following permissions:

{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Action": [
        "s3:ListAllMyBuckets",
        "s3:CreateBucket",
        "s3:PutBucketOwnershipControls"
      ],
      "Resource": "*"
    },
    {
      "Effect": "Allow",
      "Action": [
        "s3:PutBucketPublicAccessBlock",
        "s3:PutBucketAcl",
        "s3:PutBucketCORS",
        "s3:GetObject",
        "s3:PutObject",
        "s3:PutObjectAcl",
        "s3:ListBucket"
      ],
      "Resource": "arn:aws:s3:::next-videos-*"
    }
  ]
}
