# Prompt Guide: Nano Banana 2 → Grok Video Pipeline

## Image Prompts (Nano Banana 2)

Design for animatability — pick subjects with clear motion potential.

**Good subjects:**
- Landscapes with atmospheric elements (mist, water, clouds, fire)
- Portraits with ambient lighting
- Cityscapes with movement opportunities (traffic, crowds, rain)
- Nature scenes (ocean, forest, sky)

**Color palette control:**
- Specify hex codes: `"using #f6f4f0 as background, #2d6dc3 as main blue"`
- Name palettes: `"warm amber and deep teal palette"`
- Style anchors: `"Chinese ink wash", "Mughal miniature", "Japanese woodblock"`

## Animation Prompts (Grok Imagine)

Describe **motion**, **camera**, and **atmosphere** — not the scene (that's already in the image).

**Motion vocabulary:**
- `gentle ripples`, `slowly drifts`, `softly sways`, `light flickers`
- `subtle breathing motion`, `leaves rustling`, `steam rising`

**Camera vocabulary:**
- `slow push-in`, `gentle pan left`, `slow aerial descent`
- `handheld feel`, `static shot`, `orbiting slowly`

**Atmosphere:**
- `golden hour light shifts`, `clouds pass overhead`
- `fog thickens`, `rain begins to fall`, `wind picks up`

## Example Pipelines

### Cultural landscape series
```bash
./pipeline.sh \
  "A serene mountain and water scene, Chinese ink wash painting style, misty peaks, #f6f4f0 background" \
  "Mist slowly drifts between peaks, water ripples gently, slow push-in camera" \
  chinese-landscape
```

### Cinematic portrait
```bash
./pipeline.sh \
  "Portrait of an elderly scientist in warm laboratory light, painterly oil style" \
  "Subtle breathing, warm light shifts, camera slowly orbits" \
  scientist-portrait
```

### Urban night scene
```bash
./pipeline.sh \
  "Tokyo street at night, neon reflections on wet pavement, cyberpunk palette" \
  "Rain falls, neon signs flicker, pedestrians pass, slow pan right" \
  tokyo-night
