If you've ever wanted to create your own powerful, web-based video editor—similar to popular tools like Veed.io or Descript—you're in the right place! In this step-by-step guide, we’ll show you how to build a video editor using Remotion, Next.js, and Tailwind CSS. By the end, you’ll have a solid foundation to develop your own browser-based video editing tool.

Introduction

Web-based video editors are becoming increasingly popular because of their accessibility and ease of use. By using Remotion for video rendering, Next.js for a powerful React-based framework, and Tailwind CSS for fast and customizable styling, you can build a flexible video editing tool that operates directly in the browser.

In this guide, we’ll build a simplified version of tools like React Video Editor, allowing users to arrange video clips, add text overlays, and preview their videos in real-time.

Prerequisites

Before we dive in, ensure you have the following installed:

Node.js (v14 or later)
npm (bundled with Node.js)
Code Editor (e.g., Visual Studio Code)

Having some experience with React will be helpful, but this guide will walk you through the essentials step by step.

Setting Up the Project

Create a new Next.js project with TypeScript:

Run the following command to create a new Next.js project. We’ll be using TypeScript for better type safety:

   npx create-next-app@latest video-editor --typescript
   cd video-editor

This command sets up a fresh Next.js project named video-editor with TypeScript enabled.

Install required packages:

Next, install the dependencies we need for video rendering (Remotion), icons (Lucide), and more:

   npm install @remotion/player remotion lucide-react

These packages will allow us to create a video player (@remotion/player), handle video rendering logic (Remotion), and add icon support (Lucide).

Set up Tailwind CSS:

Follow the official Tailwind CSS installation guide to integrate Tailwind with your Next.js project. Tailwind CSS will make styling the editor faster and more flexible.

Create core component files:

Now, create a new file components/react-video-editor.tsx where we’ll build the main structure for the video editor component. We’ll break this component down into smaller pieces like the timeline and video player next.

Building the Video Editor

With the project setup complete, let's move on to creating the key components of the video editor. We'll start by building the Timeline and Player components, then combine everything in the main editor component.

Timeline Component

The Timeline is where users will arrange and visualize their video clips and text overlays. This component will receive an array of video clips and text overlays and display them on a timeline.

Here’s a basic structure for the timeline component:

// components/Timeline.tsx
import React from 'react';
import { Clip, TextOverlay } from '@/types/types';

interface TimelineProps {
  clips: Clip[]; // Array of video clips
  textOverlays: TextOverlay[]; // Array of text overlays
  totalDuration: number; // The total duration of the video
}

const Timeline: React.FC<TimelineProps> = ({ clips, textOverlays, totalDuration }) => {
  // For now, we’ll just display the length of the video and the number of clips.
  return (
    <div>
      <h2>Total Duration: {totalDuration} seconds</h2>
      <p>Number of clips: {clips.length}</p>
      <p>Number of text overlays: {textOverlays.length}</p>
    </div>
  );
};

export default Timeline;

In this example, we define a Timeline component that accepts props for the video clips, text overlays, and total video duration. In future steps, we’ll update this component to display an interactive timeline with drag-and-drop functionality.

Player Component

Next, we’ll build the Player component. This component uses Remotion to render the video clips and play the video. It takes in the video clips and text overlays and passes them to Remotion’s player.

// components/Player.tsx
import React from 'react';
import { Player } from '@remotion/player'; // Import the Player component from Remotion
import { Clip, TextOverlay } from '@/types/types';

interface PlayerProps {
  clips: Clip[]; // Array of video clips
  textOverlays: TextOverlay[]; // Array of text overlays
  totalDuration: number; // Total duration of the video
}

const VideoPlayer: React.FC<PlayerProps> = ({ clips, textOverlays, totalDuration }) => {
  // Here, the Player component from Remotion will be used to render the video clips
  return (
    <div>
      <Player
        component={() => <div>Render video here</div>} // Temporary placeholder for rendering the video
        durationInFrames={totalDuration * 30} // Assuming 30 frames per second
        compositionWidth={1920} // Standard 1080p width
        compositionHeight={1080} // Standard 1080p height
        fps={30} // Frames per second
        controls // Display play/pause and other controls
      />
    </div>
  );
};

export default VideoPlayer;

In the code above, we set up the VideoPlayer component to handle video rendering using Remotion’s Player component. We pass in props such as durationInFrames (which calculates the total duration based on 30 frames per second) and specify standard video dimensions (1920x1080).

Main Editor Component

Now, let's combine the Timeline and Player components in the main editor component. This is where the state for video clips and overlays will be managed, and both components will be rendered together.

// components/react-video-editor.tsx
import React, { useState } from 'react';
import Timeline from './Timeline';
import VideoPlayer from './Player';
import { Clip, TextOverlay } from '@/types/types';

const ReactVideoEditor: React.FC = () => {
  // State to hold video clips, text overlays, and total duration
  const [clips, setClips] = useState<Clip[]>([]); // Initial state: an empty array of video clips
  const [textOverlays, setTextOverlays] = useState<TextOverlay[]>([]); // Initial state: an empty array of text overlays
  const [totalDuration, setTotalDuration] = useState(10); // Example initial duration (in seconds)

  // For now, we’ll render the VideoPlayer and Timeline components
  return (
    <div className="flex flex-col text-white">
      <VideoPlayer clips={clips} textOverlays={textOverlays} totalDuration={totalDuration} />
      <Timeline clips={clips} textOverlays={textOverlays} totalDuration={totalDuration} />
      {/* Additional controls for adding clips and overlays will go here */}
    </div>
  );
};

export default ReactVideoEditor;

In this main editor component, we manage the state of the video clips, text overlays, and total duration using React’s useState hook. For now, the state is initialized with empty arrays for clips and overlays. The VideoPlayer and Timeline components are rendered with the appropriate props.

Customizing and Extending

Now that you’ve got the basic structure of your video editor, you can begin to extend and customize its functionality. Here are a few ideas to get you started:

Drag-and-drop functionality: Enable users to rearrange clips on the timeline.
Advanced text overlays: Add support for changing fonts, colors, and animations for text.
Audio support: Allow users to upload and manage background music tracks.
Video transitions: Implement smooth transitions between different video clips.

These features will help your editor become more interactive and user-friendly, comparable to professional editing tools like Veed.io or Descript. If you are feeling stuck feel free to pull down the open source version here. Or have a play with the live version here.

Why I Created the React Video Editor

Sam Bowen-Hughes — Tue, 10 Sep 2024 03:12:53 +0000

Building a video editor from scratch is incredibly challenging. Between handling video rendering, timelines, drag-and-drop functionality, and complex user interactions, there are countless moving parts to manage. I realized early on how hard it can be, even with powerful tools like Remotion and Next.js.

The Power of Remotion and Next.js

Remotion brings incredible capabilities to the world of web-based video editing. It allows you to programmatically render videos using React components, and its flexibility means you can create truly custom video experiences. Combine this with the server-rendering and speed of Next.js, and you have the potential to build something great.

However, as powerful as these tools are, creating a video editor still requires an enormous amount of effort and expertise. Just getting the timeline functionality right — syncing frames, allowing users to edit segments, and previewing changes in real time — can feel overwhelming. These aren't things you can just "plug in and play"; they require custom solutions for each use case.

Why We Built This React Video Editor Component

After wrestling with these challenges ourselves, I set out to create a solution: a React Video Editor component that gives developers a solid foundation to build upon. By handling the most difficult parts of video editing — such as drag-and-drop timelines, Remotion integration, and video clip trimming — I allow developers to focus on what makes their product unique, rather than reinventing the wheel.

Our goal is to speed up development, providing you with a customizable and extendable codebase that you can use to build great video editing products. This component isn't just a utility; it's designed to be a building block for your next big idea, offering flexibility while taking care of the technical complexities behind the scenes.

Why Is Building a Video Editor So Hard?

Creating a video editor involves a lot more than just handling media files. The following challenges are some of the reasons why I decided to create this foundational component:

Timelines: Managing a timeline where users can adjust video segments, trim clips, and overlay text is complex. Syncing these elements with real-time video playback requires a deep understanding of both JavaScript and React state management.
Rendering and Performance: Remotion is powerful but requires careful handling to ensure smooth rendering and performance, especially when working with multiple clips and elements.
Drag-and-Drop Functionality: Creating a seamless drag-and-drop experience for video clips and text overlays is another major hurdle. Ensuring that the UI feels intuitive while also being robust in handling different media types requires a solid design and technical implementation.
