## CRITICAL GUIDELINES

### Windows File Path Requirements

**MANDATORY: Always Use Backslashes on Windows for File Paths**

When using Edit or Write tools on Windows, you MUST use backslashes (`\`) in file paths, NOT forward slashes (`/`).

### Documentation Guidelines

**NEVER create new documentation files unless explicitly requested by the user.**

---

## Quick Reference

| Shape | Filter | Command Example |
|-------|--------|-----------------|
| Rectangle | `drawbox` | `-vf "drawbox=x=100:y=100:w=200:h=150:color=red:t=fill"` |
| Grid | `drawgrid` | `-vf "drawgrid=w=iw/3:h=ih/3:t=2:color=white"` |
| Text | `drawtext` | `-vf "drawtext=text='Hello':x=10:y=10:fontsize=24"` |
| Watermark | `overlay` | `[0:v][1:v]overlay=W-w-10:10` |

| Position | Expression |
|----------|------------|
| Centered | `x=(iw-200)/2:y=(ih-150)/2` |
| Bottom-right | `x=iw-w-10:y=ih-h-10` |
| Full-width bar | `x=0:y=0:w=iw:h=80` |

## When to Use This Skill

Use for **graphics and shape overlays**:
- Drawing rectangles, boxes, borders
- Adding watermarks and logos
- Lower third graphics
- Progress bars and indicators
- Grid overlays and safe area guides

```

## Drawing Circles and Ellipses (geq)

### Using geq Filter for Circles

```bash
# Draw circle outline
ffmpeg -i video.mp4 \
  -vf "geq=lum='if(between(sqrt(pow(X-iw/2,2)+pow(Y-ih/2,2)),100,105),255,lum(X,Y))':cb='cb(X,Y)':cr='cr(X,Y)'" \
  circle_outline.mp4

# Filled circle (white)
ffmpeg -i video.mp4 \
  -filter_complex "\
    color=c=white:s=1920x1080[c];\
    [c]geq=lum='if(lt(sqrt(pow(X-W/2,2)+pow(Y-H/2,2)),200),255,0)':cb=128:cr=128[mask];\
    [0:v][mask]overlay[v]" \
  -map "[v]" \
  filled_circle.mp4
```

### Using Overlay with Circle Images

```bash
# More practical: overlay a circle image
# First create circle image
ffmpeg -f lavfi \
  -i "color=c=red:s=200x200" \
  -vf "geq=lum='if(lt(sqrt(pow(X-100,2)+pow(Y-100,2)),100),255,0)':cb=128:cr=128,format=rgba,colorchannelmixer=aa='if(lt(sqrt(pow(X-100,2)+pow(Y-100,2)),100),1,0)'" \
  -frames:v 1 \
  circle.png

# Overlay circle on video
ffmpeg -i video.mp4 -i circle.png \
  -filter_complex "[0:v][1:v]overlay=100:100" \
  video_with_circle.mp4
```

### Generate Shape Patterns

```bash
# Radial gradient
ffmpeg -f lavfi \
  -i "color=c=black:s=500x500,geq=lum='255*sqrt(pow(X-W/2,2)+pow(Y-H/2,2))/(W/2)':cb=128:cr=128" \
  -frames:v 1 \
  radial_gradient.png

# Checkerboard pattern
ffmpeg -f lavfi \
  -i "color=c=white:s=800x800,geq=lum='if(mod(floor(X/100)+floor(Y/100),2),255,0)':cb=128:cr=128" \
  -frames:v 1 \
  checkerboard.png

# Diagonal stripes
ffmpeg -f lavfi \
  -i "color=c=black:s=800x600,geq=lum='if(mod(X+Y,100)<50,255,0)':cb=128:cr=128" \
  -frames:v 1 \
  stripes.png
```

    [a]curves=preset=lighter[light];\
    [1:v]format=gray[mask];\
    [light][b][mask]maskedmerge" \
  masked_effect.mp4
```

## Generating Graphics Programmatically

### Color Bars and Test Patterns

```bash
# SMPTE color bars
ffmpeg -f lavfi -i "smptebars=size=1920x1080:duration=10" \
  -c:v libx264 -pix_fmt yuv420p \
  colorbars.mp4

# Test pattern with grid
ffmpeg -f lavfi -i "testsrc=size=1920x1080:duration=10" \
  -c:v libx264 -pix_fmt yuv420p \
  testpattern.mp4

# Solid color
ffmpeg -f lavfi -i "color=c=red:s=1920x1080:d=5" \
  -c:v libx264 -pix_fmt yuv420p \
  red.mp4
```

### Gradient Backgrounds

```bash
# Horizontal gradient
ffmpeg -f lavfi -i "gradients=s=1920x1080:c0=0x000033:c1=0x003366:duration=5" \
  -c:v libx264 -pix_fmt yuv420p \
  gradient.mp4

# Radial gradient (using geq)
ffmpeg -f lavfi \
  -i "color=c=black:s=1920x1080:d=5,geq=lum='255-255*sqrt(pow(X-W/2,2)+pow(Y-H/2,2))/sqrt(pow(W/2,2)+pow(H/2,2))':cb=128:cr=128" \
  -c:v libx264 -pix_fmt yuv420p \
  radial.mp4
```

### Noise and Texture

```bash
# Noise overlay
ffmpeg -f lavfi -i "nullsrc=size=1920x1080:duration=5,geq=lum='random(1)*255':cb=128:cr=128" \
  -c:v libx264 -pix_fmt yuv420p \
  noise.mp4

# Film grain effect
ffmpeg -i video.mp4 -f lavfi -i "nullsrc=size=1920x1080,geq=lum='random(1)*20+lum(X,Y)':cb=128:cr=128" \
  -filter_complex "[0:v][1:v]blend=all_mode=addition:all_opacity=0.1" \
  grainy.mp4
```

## Performance Tips

### Optimize Drawing Operations

```bash
# Use enable parameter to limit processing
ffmpeg -i video.mp4 \
  -vf "drawbox=x=100:y=100:w=200:h=150:color=red:t=fill:enable='between(t,5,10)'" \
  optimized.mp4

# Pre-render static graphics
# Instead of complex real-time drawing, overlay pre-made images
ffmpeg -i video.mp4 -i prerendered_graphic.png \
  -filter_complex "[0:v][1:v]overlay=10:10" \
  faster.mp4
```

### Hardware Acceleration

```bash
# Use hardware encoding for graphics-heavy output
ffmpeg -i video.mp4 \
  -vf "drawbox=x=100:y=100:w=200:h=150:color=red:t=fill" \
  -c:v h264_nvenc -preset fast \
  output.mp4
```

## Troubleshooting

### Common Issues

**"Expression syntax error"**
```bash
# Escape special characters properly
# Use single quotes around expression values
ffmpeg -i video.mp4 \
  -vf "drawbox=x='iw/2':y='ih/2':w=100:h=100:color=red:t=fill" \
  output.mp4
```

**Overlay not visible**
```bash
# Check PNG has alpha channel
ffprobe -v error -select_streams v -show_entries stream=pix_fmt overlay.png

# Convert to RGBA if needed
ffmpeg -i overlay.png -pix_fmt rgba overlay_rgba.png
```

**Text not rendering**
```bash
# Specify font file explicitly
ffmpeg -i video.mp4 \
  -vf "drawtext=text='Hello':fontfile=/path/to/font.ttf:fontsize=24:fontcolor=white" \
  output.mp4

# List available fonts
fc-list : family | sort | uniq
```

**Performance issues with complex filters**
```bash
# Reduce filter chain complexity
# Pre-render graphics
# Use lower resolution for preview
ffmpeg -i video.mp4 \
  -vf "scale=640:360,drawbox=..." \
  -preset ultrafast \
  preview.mp4
```

## Best Practices

### Design
1. Use transparency (RGBA) for overlays
2. Match overlay resolution to video
3. Use appropriate colors for visibility
4. Test on various backgrounds

### Performance
1. Pre-render complex graphics as images
2. Use enable parameter for timed effects
