FFmpeg CLI
PassAudited by ClawScan on May 1, 2026.
Overview
This is a straightforward FFmpeg wrapper for local media processing, with the main caution that it can overwrite the output files you choose.
This skill appears safe for normal local FFmpeg use. Before installing or running it, make sure ffmpeg and bc come from a trusted package source, review any generated command, and avoid choosing output paths that would overwrite important files.

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.
If the chosen output path already exists, the script can replace that file during media processing.
The script invokes the local ffmpeg tool on caller-supplied input and output paths and uses -y, which overwrites the specified output file without an additional prompt. This is consistent with the media-conversion purpose but is important for users to notice.
ffmpeg -i "$INPUT" -c:v libx264 -crf 23 -c:a aac -b:a 128k -y "$OUTPUT"
Use a new output filename or confirm backups before running the wrappers, especially when accepting an agent-suggested command.
The speed-adjustment command may fail or require an extra local utility that is not clearly declared in the registry metadata.
The speed script relies on the local bc utility in addition to ffmpeg, while the supplied registry requirement fields list no required binaries and SKILL.md metadata only names ffmpeg. This is an undeclared local dependency, not evidence of hidden installation or remote code.

Install ffmpeg and any needed local utilities such as bc from trusted package sources; publishers should declare all required binaries.
