Lingjian: Local AI Short Video Workflow with Human Approval
aigclink · x · 2026-07-20
blcaptain-lingjian-video (Lingjian) is an open-source Chinese short video generation skill. Unlike black-box "one-click generation" tools that blindly retry, it focuses on an auditable, editable, and traceable workflow.
Core Mechanics:
- Three Human Approval Gates: User confirmation is required before scripting, voiceover, and rendering. Approvals are cryptographically bound to the content; modifying content invalidates the approval.
- Local Director Console: A local console displays candidate shots for preview and confirmation without relying on third-party libraries or external requests.
- Data Security: Keys are read exclusively from the local environment, outputs are stored locally, and it supports inheriting logged-in Claude/Codex CLI sessions.
Technical Highlights:
- Distinguishes between "release-grade" and "preview-grade" using FFmpeg for hardware rendering, subtitle burning, and loudness normalization.
- Uses Whisper for word-level alignment to generate accurate timelines, syncing visuals precisely with audio via silencedetect.
- Supports detecting Volcengine Ark keys to directly call Seedance for dynamic video generation; falls back to local LLMs and Kokoro for sample generation if no key is found.
