# capcut-edit

## What it does

The skill sits on top of the `capcut` CLI, which reads and writes the project files: `draft_content.json`, `draft_info.json`, `draft_meta_info.json` and `template-2.tmp`. Version 0.11 detects readable timelines and keeps them in sync, so edits do not drift between copies. Drafts live in `~/Movies/CapCut/User Data/Projects/com.lveditor.draft/<project>/` on macOS and `%LOCALAPPDATA%\CapCut\User Data\Projects\com.lveditor.draft\<project>\` on Windows; JianYing uses a `JianyingPro` path instead.

Inside is a client library under `scripts/`. `anim.sh` attaches one of 9 CapCut intro and outro animations, with `fade-in.sh` and `fade-out.sh` as thin wrappers. `ken-burns.sh` builds scale and pan keyframes, `long-to-short.sh` cuts a range and stamps a title plus CTA, `stamp-cta.sh` applies a saved text template. The scripts resolve the `capcut` entry point themselves: `$CAPCUT_CLI` first, then the repo build, then an installed `node_modules/capcut-cli`, then `capcut-cli` or `capcut` on `PATH`.

Close the project in CapCut before editing and reopen it after — an open editor is the usual reason a write conflicts. Every write is conflict-checked, prepared atomically, and leaves a `.bak` plus rolling history snapshots. Do not reach for `--force-write` unless you accept overwriting state that changed on disk. On audio segments `clip` is `null`, since opacity and scale do not apply there. Batch writes are transactional: one failing operation writes nothing at all.

```bash
npx skills add renezander030/capcut-cli --skill capcut-edit -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/capcut-edit/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/renezander030/capcut-cli/tree/HEAD/skills/capcut-edit/SKILL.md

## When to use it
- rewrite subtitle text inside a CapCut draft
- shift every segment timing by half a second
- cut a long video into a short with a title and CTA
- attach a fade-in or ken-burns move to one clip
- generate karaoke captions from an audio track

## Example prompts
- list the tracks in my-video and find every text segment
- shift all segments by +0.5s and set volume 0.5 on d4e5f6
- cut long-video into a short with a title and a CTA

description: Edit CapCut / JianYing video projects — read and write subtitles, timing, speed, volume, templates, animations (fade/ken-burns), and cut long-form to shorts. Use when the user mentions capcut, jianying, subtitles, video editing, draft_content.json, draft_info.json, or cutting videos — in English or Chinese (剪映, 字幕, 草稿, 剪辑, 切片, 视频编辑).

# capcut-edit

CLI for editing CapCut / JianYing drafts through a version-aware store. v0.11 detects and synchronizes readable timelines across `draft_content.json`, `draft_info.json`, `draft_meta_info.json`, and `template-2.tmp`.

## Project locations

- **macOS**: `~/Movies/CapCut/User Data/Projects/com.lveditor.draft/<project>/`
- **Windows**: `%LOCALAPPDATA%\CapCut\User Data\Projects\com.lveditor.draft\<project>\`
- **Windows (JianYing / 剪映)**: `%LOCALAPPDATA%\JianyingPro\User Data\Projects\com.lveditor.draft\<project>\`

## Core principle — deterministic scripts

Any recipe involving more than one `capcut` call, any arithmetic, or any branching ships as a parameterised shell script in `scripts/`. Claude invokes the script with inputs; the script runs a fixed sequence. If a recipe can be a script, it **must** be a script — not a narrative in `references/`.

`references/workflows.md` documents *which script to call and why*, never a reconstructable sequence.

## Progressive disclosure

Start broad, drill into what you need. Never dump full project JSON.

```bash
capcut info <project> -H           # overview
capcut doctor -H                   # installed media/transcription capabilities
capcut diagnose <project> -H       # canonical files, divergence, editor safety
capcut tracks <project> -H         # all tracks
capcut materials <project> -H      # material summary
capcut segments <project> -H       # segments with timing
capcut segment <project> <id>      # one item, full detail
```

## Output modes

- **JSON** (default): pipe to `jq`, feed to scripts.
- **`-H`**: human-readable tables.
- **`-q`**: quiet, exit code only — for write commands in scripts.

## Batch writes

```bash
echo '{"cmd":"set-text","id":"a1b2c3","text":"Fixed"}
{"cmd":"volume","id":"d4e5f6","volume":0.5}' | capcut batch <project>
```

Operations: `set-text`, `shift`, `shift-all`, `speed`, `volume`, `opacity`, `trim`.
