video-cut (Plan-driven Video Cutting)

Executes an agent-authored clip plan: validates clip_plan.json, snaps cut boundaries safely, and concatenates the selected ranges into edited_source.mp4.

Image & VideoAdvanced★ 541⑂ 103AI score 8/10Last updated: Sep 28, 2026

What it does

  • Validates and normalizes work_dir/clip_plan.json, emitting clip_plan_validated.json with clip_id, source/output times and durations.
  • Snaps boundaries away from flash-frame risk near hard scene cuts, then final-snaps to reliable sentence ends or natural pauses so dialogue is never cut mid-sentence.
  • Concatenates the chosen ranges into edited_source.mp4 with no extra re-encoding beyond what stitching requires.
  • Blocks overlapping/duplicate ranges by default (--allow-overlap to opt in) and hard-blocks unsafe boundaries with unsafe_clip_sentence_boundary.
  • Legacy single-stage path also maps source-time narration.json into narration_mapped.json.

Who it's for

  • Creators building movie/series recap videos through a semi-automated pipeline.
  • Editors who want scene selection and cutting to be reproducible via scripts.
  • Users of the companion skills in the same repo (ASR anchors, recap_story_plan).

Examples

  • Condense a 2-hour film into a 10-minute source: python3 scripts/cut.py movie.mp4 --work-dir work --target-duration 10m --no-narration-map
  • Record intent in reason: b02 | turn | power: A→B | POV=heroine | in=after the question lands | out=silence ends.
  • Reuse the same shot twice: enable --allow-overlap and disambiguate narration with source_clip_id.

Let Claude do it — paste this into Claude Code

Install the skill I found on Claude Skill Mart.
Copy the skills/video-cut folder from the GitHub repo worldwonderer/video-recap-skills into my ~/.claude/skills/video-cut/.
When it's done, tell me in one line what this skill can do.

Install with a command instead

git clone https://github.com/worldwonderer/video-recap-skills.git && mkdir -p ~/.claude/skills && cp -r video-recap-skills/skills/* ~/.claude/skills/

⚠ This is a third-party skill. Check the source repository before installing.

  1. Open a terminal and go to a folder of your choice.
  2. Clone the repo: git clone https://github.com/worldwonderer/video-recap-skills.git
  3. Create the skills folder: mkdir -p ~/.claude/skills
  4. Copy the skills: cp -r video-recap-skills/skills/* ~/.claude/skills/ (copy the whole set — video-cut consumes artifacts from sibling skills).
  5. Verify prerequisites: python3 -V and ffmpeg -version.
  6. Restart Claude Code and ask something like "cut this video for a recap". Note this skill is not user-invocable; it is triggered by the orchestrating recap workflow.
