video-builder-skill

Create short narrated videos from text scripts, simple timelines, or still images using Python and ffmpeg, with optional edge-tts voiceover. Use when the user asks for an MP4 render, narration generation, or a simple explainer video build.

Render and validate an MP4 from an existing `video-builder` spec JSON using the bundled Python pipeline. Use when a spec already exists and the job is actual rendering, not story or spec design.

Build a minimal JSON render spec for the local video pipeline from script lines, still images, or narration assets. Use when the spec artifact must exist before any MP4 render can run.
