How RepoClip Generates Videos from GitHub Repos
A detailed walkthrough of RepoClip's AI pipeline — from pasting a GitHub URL to getting a finished promotional video in minutes.
What Happens When You Paste a GitHub URL?
RepoClip's entire workflow starts with a single GitHub URL. You paste it into the dashboard, optionally add custom instructions, and click Generate. Behind the scenes, a multi-stage AI pipeline takes over. The system fetches your source code, analyzes it with AI, generates images and narration, and renders a finished video. The whole process typically takes under 5 minutes.
Step 1: Code Fetching
RepoClip reads your repository's file tree and selects relevant source files. It supports TypeScript, JavaScript, Python, Go, Rust, Java, Kotlin, Swift, and more. Documentation files like README and YAML configs are also included to understand project context. Files are filtered by size and relevance — test files, build artifacts, and dependencies are excluded automatically.
Step 2: AI Code Analysis
The fetched code is sent to Gemini 2.5 Flash, which analyzes the codebase structure, identifies key features, and generates a video script. The AI determines what your project does, who it is for, and what makes it unique. It creates a scene-by-scene breakdown including narration text, visual descriptions, and timing. If you provided custom instructions — such as focusing on a specific feature or using a particular tone — the AI incorporates those into the script.
Step 3: Asset Generation
Images and narration are generated in parallel for each scene. Visuals are created using Nano Banana 2 (via Fal.ai), producing original illustrations that match each scene's theme. Narration is generated using OpenAI's text-to-speech API with a voice selected by the AI based on your project's character. You can also request a specific voice or style through custom instructions.
Step 4: Video Rendering
All assets are composed into a final video using Remotion, rendered on AWS Lambda. The output is a professional MP4 file with synchronized narration, scene transitions, and background music. Resolution depends on your plan: 720p for Free and Starter, 1080p for Pro, and 4K for Agency.
Private Repositories
RepoClip supports both public and private GitHub repositories. For private repos, you connect your GitHub account via OAuth during sign-up. RepoClip only requests the minimal permissions needed to read your code for analysis. Your code is used solely for video generation and is never stored permanently.
