video-remove-audio: Design & UI for AI Agents | OpenAgentSkill

Overview

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.

Read full documentation

Source documentation, not instructions for this website. Review permissions before running any commands.

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

.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

.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.

# 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](../skill-dependency-manager.md) — 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

1. Use the bundled script, not hand-written `ffmpeg -i … -an` commands.
2. Always uses **stream copy** for video (`-c:v copy -an`).
3. This removes **all** audio; it does **not** isolate or mute music while keeping dialogue (no stem separation).
4. Missing Python/FFmpeg → populate `.dependency/` per skill-dependency-manager, retry same command.
5. **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.
6. Need audio extracted instead of removed → use **video-to-wav**.
7. FFmpeg details: [reference.md](reference.md)

Listed tools are metadata hints, not tested compatibility. Agent prompts are suggested handoffs.

Start with one small task

1Read the source. Confirm the input, expected output, dependencies and permissions.
2Ask your agent for a plan. Approve setup and any costs before running a small isolated test.
3Check the output and changed files. Report only what actually ran; keep the source revision for reproduction.

Check the source for dependencies, API keys and third-party costs. A public repository does not mean every service is free.
