AI YouTube Auto Cutter & Smart Framing System

This project presents a full-stack web application designed to automate the process of converting long-form YouTube videos into short, engaging vertical clips (9:16) suitable for platforms like TikTok, Reels, and Shorts.

The system integrates AI-based face detection and smart cropping to ensure that the main speaker remains the focus throughout the video, even when multiple people are present.

Key Features

• YouTube Video Integration
  Users can directly input a YouTube URL, and the system will load and process the video automatically.

• Automatic Video Cutting (Batch Processing)
  Splits long videos into multiple short clips (e.g., 90 seconds each) with batch processing support.

• Smart Face Tracking & Framing
  Uses AI to detect and follow the active speaker’s face, ensuring proper focus in vertical format (9:16).

• Multiple Aspect Ratio Support
  Supports various output formats:
  • Landscape (16:9)
  • Vertical / Story (9:16)
  • Square (1:1)
  • Tall Feed (4:5)
• Real-Time Processing Status
  Displays system status such as:
  • Live
  • Recording
  • Capturing
  • Processing
  • Finished

• Recent Recording History
  Shows recently processed video clips for quick access and monitoring.

• Downloadable Output Clips
  Users can easily download generated clips after processing is completed.

Technologies Used

• Backend: Python (Video processing, AI detection), PHP (API & server logic)
• Frontend: HTML, CSS, JavaScript
• Video Processing: FFmpeg
• AI Processing: OpenCV (Face Detection & Tracking)
• Integration: YouTube API
• UI Design: Custom dashboard interface

System Workflow

1. User inputs YouTube link
2. System loads video metadata
3. User selects:
   • Start time
   • End time
   • Clip duration
4. AI processes video:
   • Detect faces
   • Track active speaker
5. Video is automatically split into segments
6. Output clips are generated in selected aspect ratio
7. User downloads results

Outcome

This system helps:

• Automate content repurposing for social media
• Save time in manual video editing
• Improve engagement through smart framing
• Enable scalable short-form content production
