OP here. I spent 6 months engineering this video pipeline. It replaces Opus Pro/Vizard.

The Stack: - Orchestration: N8N (Self-hosted) + Redis. - AI: Gemini 2.5 Flash (Scoring) + MediaPipe (Face tracking). - Engine: Custom FFmpeg build for auto-reframing & subtitle burn-in. - Infra: Docker Compose (7 microservices).

It's running in production. I've decided to move on to other projects, so I packaged the entire architecture/source code as a starter kit for devs who want to study or fork it.
