# GIF Sticker Maker

Convert user photos into 4 animated GIF stickers (Funko Pop / Pop Mart style).

## Style Spec

- Funko Pop / Pop Mart blind box 3D figurine
- C4D / Octane rendering quality
- White background, soft studio lighting
- Caption: black text + white outline, bottom of image

## Prerequisites

Before starting any generation step, ensure:

1. **Python venv** is activated with dependencies from [requirements.txt](references/requirements.txt) installed
2. **`MINIMAX_API_KEY`** is exported (e.g. `export MINIMAX_API_KEY='your-key'`)
3. **`ffmpeg`** is available on PATH (for Step 3 GIF conversion)

If any prerequisite is missing, set it up first. Do NOT proceed to generation without all three.

## Workflow

### Step 0: Collect Captions

Ask user (in their language):
> "Would you like to customize the captions for your stickers, or use the defaults?"

- **Custom**: Collect 4 short captions (1–3 words). Actions auto-match caption meaning.
- **Default**: Look up [captions table](references/captions.md) by **detected user language**. **Never mix languages.**

### Step 1: Generate 4 Static Sticker Images

**Tool**: `scripts/minimax_image.py`

1. Analyze the user's photo — identify subject type (person / animal / object / logo).
2. For each of the 4 stickers, build a prompt from [image-prompt-template.txt](assets/image-prompt-template.txt) by filling `{action}` and `{caption}`.
3. **If subject is a person**: pass `--subject-ref <user_photo_path>` so the generated figurine preserves the person's actual facial likeness.
4. Generate (all 4 are independent — **run concurrently**):

```bash
python3 scripts/minimax_image.py "<prompt>" -o output/sticker_hi.png --ratio 1:1 --subject-ref <photo>
python3 scripts/minimax_image.py "<prompt>" -o output/sticker_laugh.png --ratio 1:1 --subject-ref <photo>
python3 scripts/minimax_image.py "<prompt>" -o output/sticker_cry.png --ratio 1:1 --subject-ref <photo>
python3 scripts/minimax_image.py "<prompt>" -o output/sticker_love.png --ratio 1:1 --subject-ref <photo>
```

> `--subject-ref` only works for person subjects (API limitation: type=character).
> For animals/objects/logos, omit the flag and rely on text description.

### Step 2: Animate Each Image → Video

**Tool**: `scripts/minimax_video.py` with `--image` flag (image-to-video mode)

For each sticker image, build a prompt from [video-prompt-template.txt](assets/video-prompt-template.txt), then:

```bash
python3 scripts/minimax_video.py "<prompt>" --image output/sticker_hi.png -o output/sticker_hi.mp4
python3 scripts/minimax_video.py "<prompt>" --image output/sticker_laugh.png -o output/sticker_laugh.mp4
python3 scripts/minimax_video.py "<prompt>" --image output/sticker_cry.png -o output/sticker_cry.mp4
python3 scripts/minimax_video.py "<prompt>" --image output/sticker_love.png -o output/sticker_love.mp4
```

All 4 calls are independent — **run concurrently**.

### Step 3: Convert Videos → GIF

**Tool**: `scripts/convert_mp4_to_gif.py`

```bash
python3 scripts/convert_mp4_to_gif.py output/sticker_hi.mp4 output/sticker_laugh.mp4 output/sticker_cry.mp4 output/sticker_love.mp4
```

Outputs GIF files alongside each MP4 (e.g. `sticker_hi.gif`).

### Step 4: Deliver

Output format (strict order):
1. Brief status line (e.g. "4 stickers created:")
2. `<deliver_assets>` block with all GIF files
3. **NO text after deliver_assets**

```xml
<deliver_assets>
<item><path>output/sticker_hi.gif</path></item>
<item><path>output/sticker_laugh.gif</path></item>
<item><path>output/sticker_cry.gif</path></item>
<item><path>output/sticker_love.gif</path></item>
</deliver_assets>
```

## Default Actions

| # | Action | Filename ID | Animation |
|---|--------|-------------|-----------|
| 1 | Happy waving | hi | Wave hand, slight head tilt |
| 2 | Laughing hard | laugh | Shake with laughter, eyes squint |
| 3 | Crying tears | cry | Tears stream, body trembles |
| 4 | Heart gesture | love | Heart hands, eyes sparkle |

See [references/captions.md](references/captions.md) for multilingual caption defaults.

## Rules

- Detect user's language, all outputs follow it
- Captions MUST come from [captions.md](references/captions.md) matching user's language column — never mix languages
- All image prompts must be in **English** regardless of user language (only caption text is localized)
- `<deliver_assets>` must be LAST in response, no text after
