What it does

Video Remove Audio is an agent skill from godot-fun/gai. Removes all audio and music tracks from a single video file using FFmpeg, keeping the video stream (stream copy by default). Use when the user wants to mute a video, strip audio, remove soundtrack/BGM/music from MP4/MKV/MOV/WebM, export silent video, or remove audio from a cutscene clip.

Its SKILL.md is about 740 tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `reference.md`).

It sits in Media & Creative, covering Video production and Music and audio generation. It works with FFmpeg and Python. The repository describes itself as: A lightweight AI agent and skill workflow framework built with Godot. The licence is MIT.

When your agent uses it

The user wants to mute a video
Remove soundtrack/BGM/music from MP4/MKV/MOV/WebM
Export silent video

Example prompts

“Use the video-remove-audio skill to remove all audio and music tracks from a single video file using FFmpeg, keeping the video stream (stream copy…”
“/video-remove-audio”

Requirements

Python 3

Workflow steps

7 steps, taken from the first numbered list in SKILL.md.

Use the bundled script, not hand-written ffmpeg -i … -an commands.
Always uses stream copy for video (-c:v copy -an).
This removes all audio; it does not isolate or mute music while keeping dialogue (no stem separation).
Missing Python/FFmpeg → populate .dependency/ per skill-dependency-manager, retry same command.
Do not copy, move, or replace the source with muted output — tell the user where video-remove-audio/ files are; they swap assets manually…
Need audio extracted instead of removed → use video-to-wav.
FFmpeg details: reference.md

What it can do on your machine

Read from SKILL.md and the folder at commit aa1ac71. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
- python
- ffmpeg
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Video Remove Audio loads about 740 tokens when it runs. Until then it costs about 77 tokens; SKILL.md has 269 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~77
When it runs · the whole SKILL.md, loaded when a task matches: ~740

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

name: video-remove-audio
description: Removes all audio and music tracks from a single video file using FFmpeg, keeping the video stream (stream copy by default). Use when the user wants to mute a video, strip audio, remove soundtrack/BGM/music from MP4/MKV/MOV/WebM, export silent video, or remove audio from a cutscene clip.

Video Remove Audio

Strip all audio tracks (music, voice, SFX) from a supported video file via FFmpeg. Defaults preserve the video bitstream — stream-copy video (-c:v copy), drop audio (-an), no re-encode.

Rules

When this skill applies, read and follow skill-dependency-manager — run scripts as documented, install missing tools into .dependency/.

Run remove_audio.py through .dependency/python/python.exe. Never use host python / ffmpeg.
Never overwrite sources. Outputs go under video-remove-audio/.
Use the bundled script — do not hand-write equivalent FFmpeg commands.
One file per run — pass --video with a single file; repeat for each clip in a batch.

Quick Start

bash

.dependency/python/python .ai/video-remove-audio/remove_audio.py --video path/to/clip.mp4

Example:

assets/intro.mp4
  → assets/video-remove-audio/intro.mp4

Same video codec/container, no audio.

Format Defaults

Setting	Default	Notes
Video	Stream copy	No quality loss; same codec/resolution/fps
Audio	Removed (`-an`)	Drops every audio stream
Container	Same as source	Extension preserved
Already silent	Skipped	Reports `[skip]` when no audio streams

Common Flags

--video · -o / --output

bash

.dependency/python/python .ai/video-remove-audio/remove_audio.py --video clip.mp4
.dependency/python/python .ai/video-remove-audio/remove_audio.py --video clip.mp4 -o out/silent.mp4

Never overwrite source files. Input must be a single video file (--video), not a directory. Supported inputs: .mp4, .mkv, .mov, .avi, .webm, .wmv, .flv, .m4v, .mpeg, .mpg, .ts, .mts, .m2ts, .3gp, .ogv.

Agent Notes

Use the bundled script, not hand-written ffmpeg -i … -an commands.
Always uses stream copy for video (-c:v copy -an).
This removes all audio; it does not isolate or mute music while keeping dialogue (no stem separation).
Missing Python/FFmpeg → populate .dependency/ per skill-dependency-manager, retry same command.
Do not copy, move, or replace the source with muted output — tell the user where video-remove-audio/ files are; they swap assets manually when ready.
Need audio extracted instead of removed → use video-to-wav.
