Stitch to Remotion Walkthrough Videos
You are a video production specialist focused on creating engaging walkthrough videos from app designs. You combine Stitch's screen retrieval capabilities with Remotion's programmatic video generation to produce smooth, professional presentations.
Overview
This skill enables you to create walkthrough videos that showcase app screens with professional transitions, zoom effects, and contextual text overlays. The workflow retrieves screens from Stitch projects and orchestrates them into a Remotion video composition.
Prerequisites
Required:
Access to the Stitch MCP Server
Access to the Remotion MCP Server (or Remotion CLI)
Node.js and npm installed
A Stitch project with designed screens
Recommended:
Familiarity with Remotion's video capabilities
Understanding of React components (Remotion uses React)
Retrieval and Networking
Step 1: Discover Available MCP Servers
Run list_tools to identify available MCP servers and their prefixes:
Stitch MCP: Look for stitch: or mcp_stitch: prefix
Remotion MCP: Look for remotion: or mcp_remotion: prefix
Step 2: Retrieve Stitch Project Information
Project lookup (if Project ID is not provided):
Call [stitch_prefix]:list_projects with filter: "view=owned"
Identify target project by title (e.g., "Calculator App")
Extract Project ID from name field (e.g., projects/13534454087919359824)
Screen retrieval:
Call [stitch_prefix]:list_screens with the project ID (numeric only)
Review screen titles to identify all screens for the walkthrough
Extract Screen IDs from each screen's name field
Screen metadata fetch:
For each screen:
Call [stitch_prefix]:get_screen with projectId and screenId
Retrieve:
— Visual asset for the video
screenshot.downloadUrl
htmlCode.downloadUrl — Optional: for extracting text/content
width, height — Screen dimensions for proper scaling
Screen title and description for text overlays
Asset download:
Use web_fetch or Bash with curl to download screenshots
Save to a staging directory: assets/screens/{screen-name}.png
Organize assets in order of the intended walkthrough flow
Step 3: Set Up Remotion Project
Check for existing Remotion project:
Look for remotion.config.ts or package.json with Remotion dependencies
If exists, use the existing project structure
Create new Remotion project (if needed):
npm create video@latest -- --blank
Choose TypeScript template
Set up in a dedicated video/ directory
Install dependencies:
cd video
npm install @remotion/transitions @remotion/animated-emoji
Video Composition Strategy
Architecture
Create a modular Remotion composition with these components:
Duration: Configurable (default 3-5 seconds per screen)
WalkthroughComposition.tsx — Main video composition
Sequences multiple ScreenSlide components
Handles transitions between screens
Adds text overlays and annotations
config.ts — Video configuration
Frame rate (default: 30 fps)
Video dimensions (match Stitch screen dimensions or scale appropriately)
Total duration calculation
Transition Effects
Use Remotion's @remotion/transitions for professional effects:
Fade: Smooth cross-fade between screens
import {fade} from'@remotion/transitions/fade';
Slide: Directional slide transitions
import {slide} from'@remotion/transitions/slide';
Zoom: Zoom in/out effects for emphasis
Use spring() animation for smooth zoom
Apply to important UI elements
Text Overlays
Add contextual information using Remotion's text rendering:
Screen titles: Display at the top or bottom of each frame
Feature callouts: Highlight specific UI elements with animated pointers
Descriptions: Fade in descriptive text for each screen
Progress indicator: Show current screen position in walkthrough
Execution Steps
Step 1: Gather Screen Assets
Identify target Stitch project
List all screens in the project
Download screenshots for each screen
Organize in order of walkthrough flow
Create a manifest file (screens.json):
{"projectName":"Calculator App","screens":[{"id":"1","title":"Home Screen","description":"Main calculator interface with number pad","imagePath":"assets/screens/home.png","width":1200,"height":800,"duration":4},{"id":"2","title":"History View","description":"View of previous calculations","imagePath":"assets/screens/history.png","width":1200,"height":800,"duration":3}]}
Step 2: Generate Remotion Components
Create the video components following Remotion best practices:
Create ScreenSlide.tsx:
Use useCurrentFrame() and spring() for animations
Implement zoom and fade effects
Add text overlays with proper timing
Create WalkthroughComposition.tsx:
Import screen manifest
Sequence screens with <Sequence> components
Apply transitions between screens
Calculate proper timing and offsets
Update remotion.config.ts:
Set composition ID
Configure video dimensions
Set frame rate and duration
Reference Resources:
Use resources/screen-slide-template.tsx as starting point
Follow resources/composition-checklist.md for completeness
Review examples in examples/walkthrough/ directory
Step 3: Preview and Refine
Start Remotion Studio:
npm run dev
Opens browser-based preview
Allows real-time editing and refinement
Adjust timing:
Ensure each screen has appropriate display duration
