Geek Edit: Simplifying Audio and Video Processing

Geek Edit is a web platform designed to simplify the often complex processes of video and audio editing. Unlike traditional editing tools, which require downloading and have a steep learning curve, Geek Edit allows users to quickly and intuitively edit their videos and audios from their browsers. With a user-friendly interface and a range of features, Geek Edit aims to Make Content creation accessible to everyone.

Project Overview

Geek Edit is a web platform that offers a Simplified approach to audio and video processing. The project is led by a dedicated team that has developed a seamless editing experience for users. By eliminating the need for specialized software and technical expertise, Geek Edit democratizes the editing process, enabling anyone to Create professional-quality content.

Geek Edit Web Platform

The Geek Edit platform provides users with a hassle-free way to edit their videos and audios. By harnessing the power of web-Based technologies, Geek Edit removes the barriers that often accompany traditional editing software. With a simple and intuitive user interface, users can seamlessly upload their media files and start editing within seconds.

Tech Stack

Geek Edit utilizes a combination of cutting-edge technologies to deliver a seamless editing experience for users. The tech stack includes:

Front-end: React.js and TypeScript

The front-end of Geek Edit is built using React.js and TypeScript. These technologies provide a robust and flexible foundation for the platform, allowing for efficient development and optimal user experience.

MediaPipe Selfie Segmentation

Geek Edit leverages MediaPipe Selfie Segmentation to handle the removal of backgrounds from videos. This lightweight and fast machine learning solution, provided by Google, enables users to effortlessly add virtual backgrounds to their videos.

FFmpeg Command Line Tool

FFmpeg, a powerful command line tool, is used in the editor component of Geek Edit. FFmpeg provides a vast array of functions for video and audio editing, making it a versatile tool for manipulating media files.

Firebase Backend

Geek Edit employs Firebase as its backend solution. Developed by Google, Firebase offers a backend-as-a-service (BaaS) platform that provides authentication and data storage capabilities. In Geek Edit, Firebase is used for user authentication and storage of user data.

How It Works

Geek Edit is divided into two main components: the recording and the editor. Let's explore each component in Detail.

Recording

In the recording component, users have the ability to capture video and audio. This is achieved by utilizing web APIs such as Navigator.mediaDevices.getUserMedia, which retrieves the video and audio streams from the browser. Additionally, Geek Edit offers screen recording functionality using the getDisplayMedia API.

To enhance the recording experience, Geek Edit incorporates virtual background capabilities through the use of MediaPipe Selfie Segmentation. This advanced technology, also employed by Google Meet, segments the background from the user's video feed in real time. By leveraging this powerful feature, users can easily change their background or add visual effects during the recording process.

Editor

The editor component of Geek Edit provides users with a seamless interface to edit their recorded videos and audios. The front-end GUI layer emulates the changes made by users without the need to generate a new video with each alteration.

Users can perform various editing tasks, such as trimming videos, merging multiple videos, and resizing and repositioning videos. These operations are achieved by manipulating the DOM and utilizing native web APIs such as HTMLVideoElement.currentTime, play, pause, and replaceChild.

To render the final output, Geek Edit utilizes the powerful FFmpeg command line tool. By generating an FFmpeg recipe command, the desired edits are applied to the video, resulting in the creation of the final edited video.

Challenges and Learnings

Throughout the development process, the Geek Edit team encountered several challenges. These challenges served as opportunities for growth and learning. Some of the notable challenges and learnings include:

• Continuous API calling: To ensure seamless frame-by-frame calling of the Selfie Segmentation API, the team utilized web workers, allowing for background thread processing and preventing interruptions caused by tab switching.
• Efficient frame extraction: Initially, frame extraction using the FFmpeg Package proved to be time-consuming. To overcome this, the team implemented frame extraction using the Seek functionality, making the process considerably faster and more efficient.
• Syncing video and audio: Keeping video and audio in sync while allowing for separate manipulation presented a challenge. By adopting appropriate techniques, the team was able to achieve synchronization on the front-end GUI, providing users with an accurate representation of their edits.
• New learnings: Developing Geek Edit involved gaining expertise in various technologies, including Media APIs, FFmpeg, and the HTML5 canvas. The team embraced these new technologies, realizing their potential and harnessing their power to deliver a robust and user-friendly platform.

Future Aspects

Geek Edit is continuously evolving to cater to the ever-changing needs of content Creators. Some features that the team plans to implement in the future include:

• Screen recording: Introducing the ability to record the screen adds another dimension to content creation, allowing users to capture video footage directly from their screens.
• Transitions and background videos: Enhancing the editing experience by enabling users to Apply seamless transitions between video clips and add dynamic background videos.
• Adding background audio: Integrating the option to include background audio or a voiceover to enhance the overall quality and impact of the edited videos.
• Adding subtitles: Providing users with the ability to add subtitles to their videos through the utilization of text-to-speech web APIs.
• Stickers, text, and GIFs: Expanding the creative possibilities by incorporating features like stickers, text overlays, and GIFs to make videos more engaging and interactive.
• Real-time collaboration: Enabling multi-user editing in real time to facilitate collaboration on video projects.

With these future aspects in mind, Geek Edit aims to empower content creators with an increasingly versatile and user-friendly editing platform.
