codebase-video-explainer
Create evidence-backed developer explainer videos from local projects, Git repositories, or GitHub repositories. Use when the user asks to understand, onboard to, explain, visualize, or produce a video walkthrough of a codebase, architecture, request flow, module relationship, or execution path. Analyze verified source relationships first, then create architecture visuals, a storyboard, natural Chinese narration with exact TTS-derived subtitle timing, a Remotion project, and a final MP4. Prefer local Remotion, use GitHub Actions Remotion when local npm or browser access is blocked, and use FFmpeg only as the final fallback.
