Publish Video Vocal Remover
PassAudited by ClawScan on May 8, 2026.
Overview
This instruction-only skill gives disclosed ffmpeg commands for reducing voice frequencies in videos, with some normal local install and batch-file risks to review before running.
This skill appears safe and purpose-aligned as an instruction-only ffmpeg recipe. Before installing or using it, make sure you trust the ffmpeg installation source, run commands only on copies or intended files, and be careful with the batch folder and overwrite options.

Artifact-based informational review of SKILL.md, metadata, install specs, static scan signals, and capability signals. ClawScan does not execute the skill or run runtime probes.
A user may not see the ffmpeg dependency from metadata alone and may need to install software before using the skill.
The skill depends on ffmpeg and gives installation commands, while the registry metadata declares no required binaries or install spec. This is a metadata/provenance gap, but the dependency is clearly disclosed and central to the skill.
需要 ffmpeg。如果未安装： ... sudo apt-get install -y ffmpeg ... brew install ffmpeg ... conda install -y ffmpeg
Review the setup instructions before running them, install ffmpeg only from a trusted package manager, and consider declaring ffmpeg as a required binary in the skill metadata.
Running the command will consume local CPU/disk resources and create or overwrite the named output video file.
The skill instructs the agent/user to run local ffmpeg shell commands. This is expected for video/audio processing, but it is still local command execution and file writing.
ffmpeg -i "INPUT.mp4" ... -af "equalizer=f=500..." ... -y "INPUT_novoice.mp4"
Run the command only on intended files, verify the input/output paths, and remove '-y' if you want ffmpeg to ask before overwriting an existing output.
If pointed at the wrong folder, it can process many videos and replace prior generated outputs, using storage and compute time.
The batch workflow recursively processes all matching MP4 files under a chosen folder and uses '-y', which can overwrite existing '_novoice' outputs. This is disclosed and purpose-aligned, but broader than a single-file edit.
find "FOLDER_PATH" -type f -name "*.mp4" ! -name "*_novoice.mp4" -print0 | while ... ffmpeg ... -y "${f%.mp4}_novoice.mp4"Test on one file first, choose a narrow folder path, back up important media, and manually confirm before using the optional 'mv' step to replace originals.
