# Before-After — Transformation Reveal Video Prompts

Transformation content is the highest-engagement format on social media. This skill generates precise Seedance 2.0 prompts that capture the full emotional arc of change: tension, reveal, payoff.

## Input Specs

Before generating prompts, establish:

- **Subject**: What is transforming? (person, room, product, brand, body, space, logo, website)
- **From state**: Describe the before — tone, condition, mood, colors, energy
- **To state**: Describe the after — tone, condition, mood, colors, energy
- **Duration**: 4s, 6s, or 8s clip
- **Aspect ratio**: 9:16 (Reels/TikTok), 1:1 (feed), 16:9 (YouTube)
- **Transition style**: hard cut, wipe, morph dissolve, object match, time-lapse compress
- **Platform destination**: Instagram Reels, TikTok, YouTube Shorts, LinkedIn

## Material References

- Use `@material[image1]` for the "before" state photo
- Use `@material[image2]` for the "after" state photo
- Use `@material[video1]` for existing transformation footage
- Use `@material[audio1]` for background music or sound effects

## Platform Optimization

- **TikTok (9:16):** Hook by 1.5s. Transition at 2-3s mark. Text overlays in center 80%. Bottom 20% obscured by UI.
- **Instagram Reels (9:16):** Hook by 2s. Higher polish expected. Cover frame must work as grid image — pick the "after" hero moment.
- **YouTube Shorts (9:16):** Hook by 2-3s. Can run longer (up to 60s). Description provides context.
- **LinkedIn (16:9 or 1:1):** Professional tone. Slower transitions acceptable. Text overlays should include metric/result.

## 2-Second Hook Structures

### 1. The Flash Compare
Show both states in rapid alternation — before/after/before — within the first 1.5 seconds. The brain registers contrast before the viewer consciously decides to watch.

**Prompt element**: "rapid flash cut between [before state] and [after state], alternating twice in the first 1.5 seconds, creating a visual stutter effect that forces viewer attention"

### 2. The Slow Morph
Start on the "after" state. Hold for 1 second. Then slowly morph backward to the "before." Pause. Then morph forward to the "after" again. The reversal creates confusion and curiosity.

**Prompt element**: "begins on [after state], slow morph backward to [before state] over 1 second, pause, then forward morph to [after state], implying the transformation is reversible and therefore real"

### 3. The Destruction-to-Beauty
Open on maximum chaos, mess, or dysfunction. Hold for 0.5 seconds. Then a single triggering event (a hand gesture, a snap, a door opening) initiates the transformation sequence.

**Prompt element**: "opens on maximum [chaos/mess/dysfunction] state, 0.5 second hold, then [triggering gesture] initiates instant or rapid transformation to [beauty/order/completion]"

### 4. The Timeline Collapse
Show a compressed version of the entire journey — weeks or months — in the first 2 seconds via extreme time-lapse, then hold on the final result.

**Prompt element**: "hyper-compressed time-lapse of the full transformation journey in 2 seconds, frantic pace of change, then sudden freeze on the completed [after state] with a sharp focus pull"

## Transition Techniques

The transition is the emotional peak of the video. Choose deliberately.

### Hard Cut
An instantaneous frame-by-frame switch from before to after. Maximum impact. Best for dramatic, high-contrast transformations where the gap between states is enormous.

- Use when: renovation reveals, body transformations, complete brand overhauls
- Prompt element: "instantaneous hard cut from [before] to [after] at the exact midpoint of the clip, no transition frames, pure contrast"
- Timing: place at 50-60% through the video to maximize buildup

### Wipe
A directional reveal that sweeps across the frame, uncovering the after state beneath. The wipe direction carries meaning: left-to-right suggests progress, bottom-to-top suggests growth, diagonal suggests dynamism.

- Use when: room makeovers, website redesigns, product packaging updates
- Prompt element: "smooth [left-to-right / bottom-to-top / diagonal] wipe transition revealing [after state] beneath [before state], wipe speed synchronized with the beat of the background audio"
- Timing: wipe should take 0.3–0.8 seconds depending on clip length

### Morph Dissolve
The before state softly dissolves into the after, sharing screen real estate briefly. Creates an emotional, dreamy quality. Best when the transformation is about growth or healing rather than correction.

- Use when: fitness transformations, personal growth, nature transformations, seasonal changes
- Prompt element: "soft cross-dissolve morph from [before state] to [after state] over 0.8 seconds, both states share the frame at the midpoint creating an ethereal double-exposure moment"
- Avoid: high-contrast color shifts (creates muddy midpoint)

### Object Match
A specific object in the before state (a door handle, a can of paint, a barbell, a before photo) is used as a visual pivot. The camera or action traces that object, and the transition occurs mid-motion, hiding the cut in movement.

- Use when: product reveals, personal trainer content, design work
- Prompt element: "camera tracks [specific object] in continuous motion, transition hidden within the movement at the moment [object] is fully in frame, [before environment] seamlessly becomes [after environment] without breaking the motion"

### Time-Lapse Compress
The transformation itself is shown at extreme speed — real footage or simulated — collapsing hours or months into seconds. Creates a visceral sense of effort and progress.

- Use when: construction, fitness, creative projects, plant growth, cooking
- Prompt element: "extreme time-lapse compression of [transformation process], 10x to 100x speed, motion blur on hands/tools/materials, smooth deceleration to real-time upon reaching the completed [after state]"
