VideoGen Pipeline

PlaywrightTTSffmpeg

A generator that turns live application pages into narrated MP4 product walkthroughs, internal docs, and help-center articles from a single declarative run.

A scene engine drives Playwright through real pages; LLM-assisted selector discovery and live DOM bootstrapping keep recordings resilient when markup changes. Narration is grounded strictly in knowledge-base content, voiced via configurable TTS, and muxed with per-beat timing so audio and video stay in sync.

One run yields a video, written docs, and knowledge chunks that flow back into the platform's retrieval system.
