# Remotion Image & Video Masking

## Overview

This skill enables Claude to create advanced masking and layering effects in Remotion where text, images, and videos interact dynamically through composition-based masking techniques.

The workflow focuses on:
- image masking
- video masking
- layered compositions
- text occlusion effects
- depth simulation
- cinematic transitions
- frame-based masking animations

The goal is to create visually engaging scenes where elements appear naturally layered, such as text moving behind foreground objects or videos blending seamlessly through animated masks.

# Setup

Before starting:

1. Install Node.js:
   https://nodejs.org

2. Verify installation:

```bash
node -v
npm -v
```

3. Create a Remotion project:

```bash
npm init video
```

4. Start development server:

```bash
npm run dev
```

5. Open the project in VS Code.

Recommended tools:
- VS Code
- Remotion Preview
- React knowledge
- Image editing software (optional)
- PNG assets with transparency

Recommended extensions:
- ES7 React snippets
- Prettier

---

# Inputs Required

- Foreground images or videos
- Background assets
- Text overlays
- Video clips
- Animation timing information

Optional:
- Transparent PNG assets
- Alpha masks
- Branding assets
- Motion references

---

# When to Use This Skill

Use this skill when:
- creating cinematic motion graphics
- building startup launch videos
- designing layered text animations
- simulating depth in scenes
- creating premium-looking transitions
- developing social media motion content
- building visually dynamic compositions

---

# When NOT to Use

Do NOT use this skill for:
- static graphic design
- simple subtitle overlays
- non-animated compositions
- basic slideshow workflows
- projects without layered visual interaction

---

# Example Use Case

> Create a startup launch video where animated text moves behind product screenshots and video layers.

Claude should:

1. Separate foreground and background layers
2. Position masked image assets above text
3. Animate text frame-by-frame
4. Maintain clean depth illusion
5. Synchronize masking effects with scene timing
6. Ensure smooth rendering consistency

Final result should:
- feel cinematic
- create convincing depth
- maintain smooth motion
- preserve readability
- render consistently across frames

---

# Core Masking Principles

## 1. Layer Ordering Controls Depth

Masking in Remotion depends heavily on visual layer ordering.

Foreground layers should:
- sit above text
- preserve occlusion illusion
- create depth separation

Typical structure:

```plaintext
Background
↓
Animated Text
↓
Foreground Image/Video
```

Correct layer ordering creates:
- cinematic depth
- realistic occlusion
- stronger visual hierarchy

---

## 2. Use Transparent Assets Whenever Possible

PNG assets with transparency improve masking flexibility.

Best use cases:
- product cutouts
- character renders
- foreground objects
- isolated UI elements

Transparent assets make it easier to:
- hide text partially
- simulate depth
- create smooth transitions

---

## 3. Animate Everything Frame-by-Frame

All masking motion should derive from:
- `useCurrentFrame()`
- interpolation
- spring systems

Avoid:
- CSS transitions
- browser animation systems
- uncontrolled movement

Preferred APIs:
- `useCurrentFrame()`
- `spring()`
- `interpolate()`

---

## 4. Preserve Layout Stability

Masking effects often create layout instability if dimensions change during animation.

Claude should proactively prevent:
- jumping text
- resizing elements
- unstable layer positioning
- clipping artifacts

Recommended strategies:
- fixed containers
- stable positioning
- controlled transforms
- isolated animation layers

---

## 5. Use Motion to Enhance Depth

Motion should reinforce layering.

Examples:
- foreground moves slower than background
- text slides beneath objects
- masked elements reveal gradually
- layered parallax effects

Good motion design improves:
- visual clarity
- cinematic feel
- scene engagement

---

# Workflow

## 1. Plan Scene Depth

Start by identifying:
- foreground elements
- background layers
- animated text regions
- masking interactions

Define:
- which objects should hide text
- where depth transitions occur
- how motion supports layering

---

## 2. Organize Composition Structure

Separate layers clearly:

Example structure:

```plaintext
components/
  Background.tsx
  Foreground.tsx
  AnimatedText.tsx
```

Benefits:
- easier debugging
- reusable masking logic
- cleaner animation structure

---

## 3. Create Foreground Masks

Use:
- transparent PNGs
- cropped video layers
- isolated foreground elements

Position foreground layers above animated text.

This creates:
- hidden text effects
- depth simulation
- cinematic layering

---

## 4. Animate Text & Layers

Use:
- `useCurrentFrame()`
- `spring()`
- interpolation

Example animation goals:
- text sliding behind objects
- layered reveals
- cinematic transitions
- depth-enhancing motion

Preferred motion style:
- smooth
- controlled
- deterministic

Avoid:
- sudden jumps
- uncontrolled easing
- browser-dependent transitions

---

## 5. Synchronize Scene Timing

Ensure:
- masking aligns with motion
- transitions remain readable
- visual hierarchy stays clear

Subtitle timing and masking timing should remain synchronized frame-by-frame.

---

## 6. Validate Rendering Quality

Before export validate:
- masking alignment
- layer ordering
- text readability
- motion smoothness
- layout stability

Check frame-by-frame for:
- clipping issues
- unstable positioning
- visual artifacts

---

## 7. Render Final Video

Render output:

```bash
npm run build
```

or:

```bash
npx remotion render
```

Preferred export:
- MP4
- high bitrate for masking-heavy scenes

---

# Output Expectations

The final output should include:
- cinematic masking effects
- smooth layered motion
- stable compositions
- convincing depth simulation
- production-ready rendered video

The workflow itself should remain:
- reusable
- modular
- render-safe
- maintainable

---

# Execution Strategy (for AI agents)

The agent should:

1. Structure scenes around visual depth
2. Maintain clear layer hierarchy
3. Use masking to enhance storytelling
4. Animate all motion frame-by-frame
5. Preserve layout stability during transitions
6. Validate rendering consistency before export

The workflow should optimize for:
- cinematic quality
- visual clarity
- motion smoothness
- rendering consistency
- scene readability

---

# Best Practices

- Keep foreground layers clean and isolated
- Use transparent assets whenever possible
- Avoid cluttered masking compositions
- Validate scenes frame-by-frame
- Keep motion smooth and intentional
- Maintain readability during masking
- Reuse layered animation patterns

---

# Notes

- Layer ordering is critical for convincing masking effects
- Transparent assets significantly improve flexibility
- Stable layouts improve cinematic quality
- Subtle masking often looks better than aggressive effects
- Motion design strongly affects depth perception
