composio-community 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

- 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

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:
- Separate foreground and background layers
- Position masked image assets above text
- Animate text frame-by-frame
- Maintain clean depth illusion
- Synchronize masking effects with scene timing
- 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:
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:
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:
npm run build
or:
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:
- Structure scenes around visual depth
- Maintain clear layer hierarchy
- Use masking to enhance storytelling
- Animate all motion frame-by-frame
- Preserve layout stability during transitions
- 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
