lightflow-video-render-edit

# LightFlow Video Render Edit Use `lightflow.video_render_edit` to render a `lightflow.video.edit-plan.v1` plan. `lfw run` executes the package-owned runner, which validates media bounds, normalizes video and audio streams, preserves source audio, supplies silence for clips without audio, and atomically installs the MP4. It rejects an `output_path` that resolves to any source media file. ## Runtime The workflow crate contains a Rust-native `runner.v1` binary. The runner must return all declared outputs, existing artifact files, and a replay fingerprint. ## Contract - Workflow id: `lightflow.video_render_edit` - Required input `edit_plan`: JSON edit decision plan. - Required input `output_path`: destination MP4 path. - Output `video`: rendered video artifact metadata. - Output `video_path`: rendered MP4 path. - Output `render_summary`: readable render summary. ## CLI Usage ```bash lfw run lightflow.video_render_edit \ --input edit_plan='{"schema":"lightflow.video.edit-plan.v1","timeline":[{"clip_id":"intro","path":"media/intro.mp4","start":0,"end":2.5,"title":"Hook"}],"output":{"aspect_ratio":"16:9","fps":30,"width":1280,"height":720,"max_duration_seconds":30}}' \ --input output_path='"output/auto-edit-demo.mp4"' ``` ## API Usage ```bash curl -sS -X POST http://127.0.0.1:5174/workflows/lightflow.video_render_edit/run \ -H 'content-type: application/json' \ -d '{"inputs":{"edit_plan":{"schema":"lightflow.video.edit-plan.v1","timeline":[{"clip_id":"intro","path":"media/intro.mp4","start":0,"end":2.5,"title":"Hook"}],"output":{"aspect_ratio":"16:9","fps":30,"width":1280,"height":720,"max_duration_seconds":30}},"output_path":"output/auto-edit-demo.mp4"}}' ``` Update this skill whenever the edit plan schema, render command, inputs, outputs, or runtime behavior changes. Run the crate's Rust tests and Clippy after any renderer change.
