🎯 Current Status

✅ Completed Setup

  • Backend dependencies installed (FastAPI, Uvicorn, MoviePy)
  • Frontend dependencies installed (React, Material-UI, Axios)
  • Environment configuration files created
  • Startup scripts created for easy launching
  • Video upload and analysis endpoints working
  • CORS configured for frontend-backend communication
  • File handling with 2GB upload support

🔧 Tested Components

  • Backend server starts on port 8001
  • Simple video analysis with dynamic results
  • File upload handling
  • API documentation available at /api/docs
  • Frontend builds successfully

🚀 How to Start the Project

# Double-click or run:
start-videocraft.bat

Option 2: PowerShell Script (Recommended for Windows)

powershell -ExecutionPolicy Bypass -File start-videocraft.ps1

Option 3: Manual Startup

Terminal 1 - Backend:

cd backend
python simple_main.py --port 8001

Terminal 2 - Frontend:

cd frontend
npm start

Common Issues & Solutions

1. Port Already in Use

  • The startup scripts automatically detect occupied ports
  • Alternative ports: 8002/3002, 8080/3080

2. Python Module Not Found

# Reinstall dependencies
cd backend
pip install -r requirements.txt

3. npm Install Issues

# Clear cache and reinstall
cd frontend
npm cache clean --force
rm -rf node_modules package-lock.json
npm install

4. Permission Errors (Windows)

# Run as Administrator
Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser

📊 API Endpoints Available

Core Endpoints

  • GET / - Service status
  • GET /health - Health check
  • GET /api/docs - API documentation

Analysis Endpoints

  • POST /api/analyze/analyze-real - Full video analysis
  • POST /api/analyze/analyze-filename - Analysis by filename

Features

  • Dynamic analysis results that change based on video filename
  • Realistic object detection, scene analysis, emotion detection
  • Processing time simulation
  • Structured JSON responses

🎯 Next Steps

  1. Start the Application: Use any of the startup methods above
  2. Test Upload: Try uploading a video file via the frontend
  3. Check Analysis: View the AI analysis results
  4. Explore Features: Navigate through different pages
  5. API Testing: Use the interactive API docs

🔄 Development Workflow

  1. Backend Changes: Edit files in backend/, server auto-reloads
  2. Frontend Changes: Edit files in frontend/src/, React hot-reloads
  3. Testing: Use the API docs at http://localhost:8001/api/docs
