# claude-gif-convert -- Video, Image, and SVG to GIF Conversion

Four conversion modes for turning any visual source into an optimized GIF.

## Mode Detection

Determine the mode from the input:

| Input | Mode | Pipeline |
|-------|------|----------|
| `.mp4`, `.webm`, `.mov`, `.avi`, `.mkv` | A: Video to GIF | ffprobe analyze --> gif_convert.sh |
| Directory of `.png`/`.jpg`/`.webp` images | B: Image Sequence | glob + sort --> gif_frames.py |
| Text description of progressive scenes | C: AI Image Sequence | AI generate N frames --> gif_frames.py |
| `.svg` file (animated or static to animate) | D: SVG to Transparent GIF | Playwright capture --> FFmpeg palette |

---

## Mode A: Video to GIF

Convert a video file to an optimized GIF using FFmpeg two-pass palette generation.

### Procedure

1. **Analyze source video**:
```bash
ffprobe -v error -show_entries format=duration,size -show_entries stream=width,height,r_frame_rate,codec_name -of json INPUT.mp4
```

2. **Determine segment** (if video is long, ask user which portion):
   - Full video: omit `--start` and `--duration`
   - Segment: specify `--start SS --duration SS`
   - Recommendation: GIFs should be 1-5 seconds. Warn if duration > 10s.

3. **Pre-flight check**:
```bash
bash ~/.claude/skills/claude-gif/scripts/preflight.sh INPUT.mp4 OUTPUT.gif
```

4. **Convert**:
```bash
bash ~/.claude/skills/claude-gif/scripts/gif_convert.sh \
  --input INPUT.mp4 \
  --preset web \
  --output ~/Documents/gif_output/output.gif
```

5. **Report result** (gif_convert.sh outputs JSON with size, dimensions, settings).

### Preset Selection Guide

- User says "for Discord" or file must be tiny --> `--preset discord`
- User says "for Slack" --> `--preset slack`
- User says "for Twitter/X" --> `--preset twitter`
- User says "high quality" or "best quality" --> `--preset hq`
- No preference stated --> `--preset web`
- User specifies exact dimensions/fps --> omit preset, pass explicit flags

### Advanced Options

```bash
bash ~/.claude/skills/claude-gif/scripts/gif_convert.sh \
  --input INPUT.mp4 \
  --fps 12 \
  --width 320 \
  --start 5.5 \
  --duration 3 \
  --dither bayer:bayer_scale=3 \
  --stats-mode diff \
  --colors 128 \
  --loop 0 \
  --output ~/Documents/gif_output/output.gif
```

## Mode B: Image Sequence to GIF

Assemble a directory of images (PNG, JPG, WebP) into a GIF.

### Procedure

1. **Identify images**:
```bash
ls /path/to/frames/*.png | head -5
ls /path/to/frames/*.png | wc -l
```

2. **Verify order**: Images should be named with sequential numbering (e.g., `frame_001.png`, `frame_002.png`). If not, they will be sorted alphabetically.

3. **Pre-flight check**:
```bash
bash ~/.claude/skills/claude-gif/scripts/preflight.sh /path/to/frames/frame_001.png OUTPUT.gif
```

4. **Assemble**:
```bash
~/.video-skill/bin/python3 ~/.claude/skills/claude-gif/scripts/gif_frames.py \
  --input-dir /path/to/frames/ \
  --pattern "*.png" \
  --fps 15 \
  --width 480 \
  --preset web \
  --output ~/Documents/gif_output/sequence.gif
```

### Options

- `--input-dir`: Directory containing frame images
- `--pattern`: Glob pattern to match frames (default: `*.png`)
- `--fps`: Playback frame rate
- `--width`: Output width (height auto-calculated)
- `--preset`: Quality preset (discord/slack/twitter/web/hq)
- `--output`: Output GIF path
- `--sort`: Sort order: `name` (default), `mtime`, `natural`

---

## Mode C: AI Image Sequence to GIF

Generate N image frames using AI (Gemini via banana MCP or FLUX.2) with progressive
prompt changes, then assemble into a stop-motion or animated GIF.

### Procedure

1. **Plan the sequence**: Determine what changes between frames.
   - Example: "sunrise over mountains" -- 8 frames from dark blue to golden yellow
   - Example: "flower blooming" -- 12 frames from bud to full bloom

2. **Generate frames** using progressive prompts:

**Option A: Gemini via banana MCP tool** (recommended for consistency):
```
For each frame i (0 to N-1):
  gemini_generate_image with prompt:
    "Frame {i+1} of {N}: [base description], [progressive change at stage i/N],
     consistent style, flat illustration, limited color palette, square format"
```

**Option B: FLUX.2 via image_generate.py** (local, no API cost):
```bash
~/.video-skill/bin/python3 ~/.claude/skills/claude-video/scripts/image_generate.py \
  --prompt "Frame {i} of {N}: [description with progressive change]" \
  --width 512 \
  --height 512 \
  --output /tmp/claude-gif/frames/frame_{i:04d}.png
```

3. **Assemble frames**:
```bash
~/.video-skill/bin/python3 ~/.claude/skills/claude-gif/scripts/gif_frames.py \
  --input-dir /tmp/claude-gif/frames/ \
  --fps 4 \
  --width 480 \
  --preset web \
  --output ~/Documents/gif_output/ai_sequence.gif
```

Low FPS (2-6) works best for AI image sequences since each frame is a distinct "scene".

### Tips for AI Image Sequences

- **Consistency is hard**: AI models may vary style between frames. Mitigate by:
  - Including strong style anchors in every prompt ("pixel art style", "watercolor style")
  - Using the same seed if the tool supports it
  - Keeping the composition simple and consistent
- **Frame count**: 6-12 frames is the sweet spot (more = more variation = less consistent)
- **Low FPS**: 2-6 fps gives a charming stop-motion look and hides inter-frame inconsistency

## Mode D: Animated SVG to Transparent GIF

Convert an animated SVG (CSS animations, SMIL, or JavaScript) to a GIF with
transparency support. Uses Playwright headless Chromium to capture frames.

### When to Use

- Converting SVG animations from the `svg-animate` skill to shareable GIFs
- Creating transparent logo animations for embedding
- Making animated icons, stickers, or UI elements with transparency
- Any SVG with `<animate>`, `@keyframes`, or GSAP animations

### Procedure

1. **Analyze the SVG**: Check for animation type and duration.
```bash
grep -E '<animate|@keyframes|animation:|requestAnimationFrame' input.svg | head -5
```

2. **Determine animation duration**: Parse from CSS `animation-duration` or SMIL `dur` attribute.

3. **Create Playwright capture script**:
```bash
cat > /tmp/claude-gif/capture_svg.js << 'SCRIPT'
const { chromium } = require('playwright');

(async () => {
  const svgPath = process.argv[2];
  const outputDir = process.argv[3];
  const fps = parseInt(process.argv[4] || '15');
  const durationMs = parseInt(process.argv[5] || '3000');
  const width = parseInt(process.argv[6] || '480');
  const height = parseInt(process.argv[7] || '480');

  const totalFrames = Math.ceil((durationMs / 1000) * fps);
  const frameInterval = durationMs / totalFrames;

  const browser = await chromium.launch();
  const page = await browser.newPage();
  await page.setViewportSize({ width, height });

  // Load SVG with transparent background
  const svgUrl = `file://${svgPath}`;
  await page.goto(svgUrl, { waitUntil: 'networkidle' });

  // Inject transparent background
  await page.evaluate(() => {
    document.body.style.background = 'transparent';
    document.documentElement.style.background = 'transparent';
  });

  // Capture frames
  for (let i = 0; i < totalFrames; i++) {
    const frameNum = String(i).padStart(4, '0');
    await page.screenshot({
      path: `${outputDir}/frame_${frameNum}.png`,
      omitBackground: true,  // Transparency support
    });
    await page.waitForTimeout(frameInterval);
  }

  await browser.close();
  console.log(JSON.stringify({ frames: totalFrames, fps, duration_ms: durationMs }));
})();
SCRIPT
```

4. **Capture frames**:
```bash
mkdir -p /tmp/claude-gif/svg_frames
node /tmp/claude-gif/capture_svg.js \
  "$(realpath input.svg)" \
  /tmp/claude-gif/svg_frames \
  15 \
  3000 \
  480 \
  480
```

5. **Assemble with transparency** using FFmpeg two-pass with `reserve_transparent=1`:
```bash
# Pass 1: Generate palette with transparency reserved
ffmpeg -y -framerate 15 -i /tmp/claude-gif/svg_frames/frame_%04d.png \
  -vf "palettegen=reserve_transparent=1:stats_mode=diff:max_colors=255" \
  /tmp/claude-gif/palette.png

# Pass 2: Apply palette with transparency
ffmpeg -n -framerate 15 -i /tmp/claude-gif/svg_frames/frame_%04d.png \
  -i /tmp/claude-gif/palette.png \
  -lavfi "paletteuse=dither=bayer:bayer_scale=3:alpha_threshold=128" \
  -loop 0 \
  ~/Documents/gif_output/transparent.gif
```

Key FFmpeg flags for transparent GIFs:
- `reserve_transparent=1`: Reserves one palette slot for transparency
- `max_colors=255`: 255 colors + 1 transparent = 256 total
- `stats_mode=diff`: Only analyze changing pixels (optimal for animations)
- `alpha_threshold=128`: Pixels with alpha < 128 become transparent (adjust 0-255)
- `dither=bayer:bayer_scale=3`: Ordered dithering works best with transparency

6. **Cleanup**:
```bash
rm -rf /tmp/claude-gif/svg_frames /tmp/claude-gif/capture_svg.js /tmp/claude-gif/palette.png
```

### SVG Preparation Tips

- SVGs should have explicit `width` and `height` attributes (not just `viewBox`)
- If the SVG uses percentage-based sizing, wrap it in an HTML file:
```html
<!DOCTYPE html>
<html><head><style>
  body { margin: 0; background: transparent; overflow: hidden; }
  svg { width: 480px; height: 480px; }
</style></head>
<body>
  <!-- SVG content here -->
</body></html>
```
- CSS animations: ensure `animation-iteration-count: infinite` for seamless capture
- SMIL animations: set `repeatCount="indefinite"`

---

## Output Conventions

- Default output directory: `~/Documents/gif_output/`
- Naming: descriptive, lowercase, underscores: `campfire_loop.gif`, `logo_transparent.gif`
- Always report final file size, dimensions, frame count, and duration
- If result exceeds target platform size, suggest running through `claude-gif-optimize`

## Error Recovery

| Error | Cause | Fix |
|-------|-------|-----|
| `No such file or directory` | Input path wrong | Verify with `ls`, use absolute paths |
| Huge GIF (>20MB) | Long video, high res | Trim duration, reduce width, use preset |
| No transparency in output | SVG has opaque background | Add `omitBackground: true`, check SVG has no `<rect>` background |
| Playwright not installed | Missing dependency | `npx playwright install chromium` |
| Frames out of order | Non-sequential naming | Use `--sort natural` in gif_frames.py |
| Choppy animation | Too few frames or low FPS | Increase FPS or capture more frames |
