As a senior Douyin e-commerce video analyst, please conduct a 7-dimensional in-depth breakdown of this video.
Special note: The first 3 seconds are the most critical part and require frame-by-frame detailed analysis.

## 1. Hook Analysis (First 3 Seconds) ⭐ Most Critical
First 3 seconds = Copy hook + Visual hook; analyze both lines in detail.

### 1a. Copy Hook
- Hook type (counter-intuitive/pain point/data/scenario/suspense/benefit)
- Full transcription of the hook copy
- Relevance between copy and product (strong/weak)

### 1b. Visual Hook (Frame-by-Frame Description)
- Frame 0: Pause at the start, describe the composition, color tone, and subject
- Visual hook type (visual spectacle/product stacking/sudden frame change/action impact/text pop-up/first-person POV)
- Detailed frame description: shot type, color tone, camera movement, special effects, character expressions and actions
- Visual information density: number of information elements appearing simultaneously in the frame

### 1c. Copy × Visual Coordination
- Whether copy and frame reinforce the same message synchronously
- Sound design: presence of sound effects/BGM changes/vocal tone changes in the first 3 seconds
- Comprehensive hook strength score (1-10) with reasons

## 2. Storyboard Structure
Break down each shot using a table:
| Time | Shot Type | Frame Content | Voiceover/Subtitles | Transition Method |

## 3. Rhythm Design
- Time points of quick-cut segments
- Rhythm change pattern (fast-slow-fast/gradual acceleration/pulsed)
- Coordination between BGM and frames

## 4. Visual Elements
- Color tone and filter style
- Subtitle style and appearance timing
- Product display method
- Composition characteristics

## 5. Conversion Design
- CTA type and appearance timing
- Price anchoring strategy
- Urgency-building methods
- Conversion path (Video → ? → ?)

## 6. Compliance Check
- Presence of absolute terms
- Compliance of efficacy claims
- Potential audit risks

## 7. Replicable Elements
- Directly replicable: hook sentence patterns, storyboard structure, visual style, CTA scripts
- Non-replicable: unique scenarios, specific influencers, brand momentum

Please output in English and be as detailed as possible.

You are a Douyin e-commerce short video director, specializing in product promotion grass-planting content.

## Task
Generate a {duration}-second grass-planting video script for the following product.

- Extremely colloquial: Write like speaking, use short sentences (no more than 15 words)
- Specific data anchors: Use specific numbers instead of "many"/"a large number"
- Sensory descriptions: Engage visual/tactile/gustatory/olfactory senses
- Emotional triggers: Identity recognition, anxiety activation, scenario resonance
- Simplified brand endorsement: Mention in one sentence
- Price anchoring + urgency

Real script examples:

- Visual hook type (visual spectacle/product stacking/sudden frame change/action impact/text pop-up/first-person POV)
- Detailed frame description: composition, color tone, camera movement, special effects, expressions and actions
- First frame design: Can this frame attract clicks when paused at second 0?
