A video-editing skill for turning raw clips into short 9:16 vertical reels. It uses an lc-editor server to build the timeline and FFmpeg, a video-processing tool, to render the result.

It helps import and analyze footage, find and preview strong shots, arrange clips, synchronize edits to music after confirmation, and export a vertical reel.

It gives the agent a defined workflow for selecting footage, deciding what to cut, handling sound, and exporting a reel. It also requires the user's choice between music and natural audio before editing the timeline.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00000	$0.02956
Opus 5.5	$0.00000	$0.01182

Security

Grade A, and why

lc-editor scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

lc-editor

Use this skill when asked to cut reels or YouTube videos from raw video clips. The lc-editor MCP server gives you tool calls to build a timeline; ffmpeg does the rendering. Default canvas is 9:16; standard SDR YouTube videos use project_create(preset="youtube"), which defaults to 1920×1080.

When to use

User asks you to edit video clips into a short reel
User asks for 9:16 vertical or 16:9 landscape video editing
User mentions cutting, trimming, or assembling footage

Quick start

The MCP server is lc-editor. Call its tools to build and export your reel.

If MCP tools are missing

Do not fall back to raw ffmpeg while lc-editor doctor is green. This is the #29 / #32 attach path.

Run lc-editor doctor (and lc-editor doctor --project <abs path> if you have a project). Confirm lc_editor_bin, ffmpeg/ffprobe, mcp_tools ~100, and project_create / import_file / import_folder / clip_add / export read ok. Doctor prints copy-paste Grok Bot / Cursor MCP JSON (command + args: ["serve"] + env).
Attach with that JSON. Pin command to the resolved lc_editor_bin (or lc-editor on PATH) and args serve. Plugin mcp.json already pins this so upgrades do not drop the connector. On Windows use C:/Users/you/my-reel or escaped backslashes if you add --project.
After pip install -U lc-editor, restart MCP: Cursor RestartMcpServers (or a new agent session); Grok Bot: re-attach (AddMcpServer). There is no RestartMcpServers CLI. Then confirm project_create is callable.
Fall back to ffmpeg only if doctor is red (missing ffmpeg, no MCP entrypoints) and you have told the owner LC is not attached. If only lc_editor_bin is missing, tools stay invisible until PATH / AddMcpServer — do not invent ffmpeg graphs yet; paste doctor's JSON.

Workflow

Inventory / index on import. Use import_folder or import_file. Import probes duration / size / capture date, builds the source proxy, and runs the cheap shot index (keyframes, shot bounds, motion / blur / audio-class) cached by content hash. Response includes shots, sheet (output/index_sheet.jpg), and per-file cached. Call media_list (sorted by capture date; filter shoot_day / role / min_motion) before you cut. Re-run media_analyze only to refresh; unchanged bytes are a no-op.
