Build a Angular Video Cutter & Trimmer Editor Using FFMPEG WASM in Browser Using TypeScript

Introduction

In this article, we will explore how to develop a video trimmer and cutter application using Angular, TypeScript, and FFMPEG WebAssembly (WASM). This project allows users to trim and cut videos directly in their web browser without the need for any desktop software.

Overview of the Application

The Angular video trimming application is straightforward and efficient. You can run the application on your local machine using localhost:3000, or you can access the live demo hosted on my website, where you can see the same functionality in action.

Key Features

Video Upload: Users can select any video file for editing.
Trimming Controls: Two sliders allow the user to specify the start and end times for the video they wish to trim.
Processing: Once the selection is made, the application processes the video and trims it to the specified length.
Download Option: Users can download the trimmed video in MP4 format.
Technology Stack: The application makes use of Angular 16, TypeScript, and the FFMPEG WebAssembly library, enabling it to function efficiently within the browser.

Getting Started

To deploy the application, you can run it locally by following these steps:

Navigate to the dist folder of the project.
Start the server using the command:
```
node more index.js
```
The server listens on port 3000, and you can access it via your web browser.

Application Structure

The Angular project comprises several key components:

Base Component: The main layout of the application.
Slider Component: Handles the input for the trim start and end times.
Video Trimmer Component: Manages the primary functionality of trimming the video based on user inputs.

Handling Video Files

Users select video files through a file input field that triggers an event handler. The selected file is then processed in memory using FFMPEG WebAssembly to handle the trimming operation efficiently without re-encoding the video, therefore speeding up the process significantly.

How FFMPEG WASM Works

FFMPEG WebAssembly allows the usage of FFMPEG directly in the browser. By not re-encoding the trimmed video segment, the process remains quick and responsive. Using the command structure provided by FFMPEG, we can effectively manage the video manipulation directly from the web application.

Benefits of This Project

This video trimmer and cutter application is an excellent project for both beginners and advanced developers. It integrates practical knowledge of video processing, web development with Angular, and TypeScript usage.
