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

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
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
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.
