skill-godot-fun-godot-framework-video-remove-audio · by godot-fun

Removes all audio and music tracks from video files 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 batch-remove audio from cutscenes.

About

Video Remove Audio

Strip all audio tracks (music, voice, SFX) from supported video files 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](../../rules/skill-dependency-manager.md) — run scripts as documented, install missing tools into .dependency/.

Quick Start

Mute a file or folder, output to silent/:

.dependency/python/python .cursor/skills/video-remove-audio/scripts/remove_audio.py path/to/video_or_folder

Example: assets/intro.mp4 → assets/silent/intro.mp4 (same video codec/container, no audio)

Batch with subfolders:

.dependency/python/python .cursor/skills/video-remove-audio/scripts/remove_audio.py Video/Cutscenes -r

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

-r · -o / --output-dir · --reencode · --dry-run · --overwrite

Force video re-encode (only if stream copy fails for the container):

.dependency/python/python .cursor/skills/video-remove-audio/scripts/remove_audio.py clip.mp4 --reencode

Never overwrite source files. The script writes only to silent/ (or -o). Supported inputs: .mp4, .mkv, .mov, .avi, .webm, .wmv, .flv, .m4v, .mpeg, .mpg, .ts, .mts, .m2ts, .3gp, .ogv, .ogg.

Agent Notes

  1. Use the bundled script, not hand-written ffmpeg -i … -an commands.
  2. Prefer stream copy — omit --reencode unless FFmpeg fails or the user asks to re-encode.
  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 silent/ 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)
