  "duration": 10,
  "format": "h264"
}

• Full resolution
• Reduced FPS to allow more light per frame
• 1/250s shutter (slower but still captures motion)
• May need additional lighting

  "height": 864,
  "fps": 120,
  "shutter_speed": 2000,
  "duration": 15,
  "format": "h264",
  "upload_enabled": true,
  "upload_destination": "s3://your-bucket/practice-sessions"
}

• Balanced quality and file size
• Longer duration to capture full practice swing
• Automatic upload to keep SD card clear

Best for: Fine-tuning your setup

{
  "width": 1456,
  "height": 1088,
  "fps": 60,
  "shutter_speed": 2000,
  "duration": 5,
  "format": "h264"
}

• Lower FPS for faster testing
• Short duration for quick iterations
• Full resolution to evaluate quality

Golf club speeds vary by club and player. Here's a guide:

Rule of thumb:

• Brighter conditions = faster shutter possible
• Indoor/cloudy = slower shutter needed (may get motion blur)
• If video is too dark, increase shutter_speed value (slower shutter)
• If motion is blurry, decrease shutter_speed value (faster shutter)

The camera has a maximum data rate. Higher resolution requires lower FPS and vice versa:

Approximate file sizes for 10-second recordings:

On a 64GB SD card:

• Full quality: ~5,300 recordings (884 hours at 10s each)
• Balanced: ~6,400 recordings (1,067 hours)
• Maximum speed: ~10,600 recordings (1,767 hours)

For best results:

1. Outdoor Bright Sun

   • Use fastest shutter speeds (1/800s - 1/1000s)
   • Maximum FPS possible
   • Consider polarizing filter to reduce glare

2. Outdoor Cloudy/Shade

   • Medium shutter speeds (1/400s - 1/500s)
   • May need to reduce FPS slightly
   • Good natural diffused light

3. Indoor

   • Slower shutter speeds (1/200s - 1/333s)
   • Reduce FPS to 90-120
   • Add LED panels (5000K-6500K color temp)
   • Need at least 2-3 lights for even coverage

4. Indoor Practice Net

   • Minimum 2x 50W LED panels
   • Position lights at 45° angles to subject
   • Avoid harsh shadows
   • May need to compromise on FPS

After changing config.json, test it:

source venv/bin/activate
python swing_camera.py --name "test_config"

Check the video:

1. Transfer to computer: scp pi@raspberrypi.local:~/swing-cam/recordings/test_config.h264 .
2. Play in VLC Media Player
3. Evaluate:
   • Is motion frozen clearly?
   • Is lighting adequate?
   • Is frame rate smooth in slow motion?
   • Is resolution detailed enough?

Adjust settings and repeat until satisfied!
