video-edit is a skill for Claude Code, Codex from floomhq/moto. It costs 117 tokens per session (2,480 once invoked), scanned A, original, MIT.

A video-editing toolkit based on FFmpeg, a program for processing video and audio files. It can cut and join clips, change speed, add text or images, mix audio, create voiceovers, add transitions, and export videos.

In plain words
What is it for?
Use it to trim or combine clips, add captions or watermarks, mix sound, generate voiceovers, add fades, review videos, and export for social platforms.
Why use it?
It turns common video changes into repeatable commands while leaving the original files untouched. Optional AI review can suggest edits and score video quality.

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.

Security

Grade A, and why

video-edit 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 6d 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.

Architecture

All editing uses ffmpeg under the hood. The Python scripts generate and execute ffmpeg commands, keeping edits non-destructive (original files untouched).

Input video/images --> Edit operations --> ffmpeg command --> Output video
                          ^
                    Gemini AI review (optional)

Workflow

Step 1: Plan the edit

Either describe what you want, or use ai-review to get suggestions:

python3 ~/.claude/skills/video-edit/scripts/video_edit.py ai-review <video_path>

This extracts frames, sends to Gemini, and returns structured edit suggestions.

Step 2: Execute edits

Chain operations. Each produces a new file (non-destructive):

# Trim to 30 seconds
python3 ~/.claude/skills/video-edit/scripts/video_edit.py trim <input> -o <output> --start 0 --end 30

# Add text overlay
python3 ~/.claude/skills/video-edit/scripts/video_edit.py text <input> -o <output> \
  --text "Your text here" --position bottom --start 0 --end 5 --style subtitle

# Mix audio
python3 ~/.claude/skills/video-edit/scripts/video_edit.py audio-mix <input> -o <output> \
  --tracks '{"voiceover.mp3": {"volume": 1.0}, "music.mp3": {"volume": 0.15, "fade_out": 3}}'

# Generate voiceover
python3 ~/.claude/skills/video-edit/scripts/video_edit.py voiceover \
  --text "Script here" --voice sarah --output voiceover.mp3

# Export for LinkedIn
python3 ~/.claude/skills/video-edit/scripts/video_edit.py export <input> -o <output> --preset linkedin

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
