Ffmpeg Skill
kajisho5 · Agent
Ffmpeg Skill gives a coding agent a local video editor. Its 42 tools wrap ffmpeg and ffprobe for cutting and joining, silence removal, fitting to a duration or aspect ratio, captions and karaoke, overlays, HDR to SDR conversion, audio clean-up, loudness, delivery checks and batch folders. Everything runs offline on your machine with no cloud and no API keys, and optional local transcription is used when a speech engine is installed.
Written by ooruby from the README of ffmpeg-skill 2.8.0.

Why it's useful
Your agent measures the real file first and checks the result afterwards, instead of guessing frame rates and codecs from the file name.
What you could do with it
- Ask your agent to keep two segments of an interview and fit the cut to exactly 60 seconds for Reels.
- Add animated captions and karaoke-style highlighting to a clip from a transcript you already have.
- Check a finished edit against a platform delivery spec and look at a contact sheet of the result.
Written from its documentation: what it says it can do, not what our checks found.
Maintenance
Not measuredNo release date is on record for this package yet. The nightly publisher check records one as it reaches each npm package, about once every ten nights.
Release activity only: it says nothing about quality or safety, and a finished small package can be fine without releases. How it is measured
- Command execution is bounded
- inventory
- python subprocess (scripts/_contract.py:640)
- python subprocess (scripts/_contract.py:686)
- python subprocess (scripts/_contract.py:763)
- python subprocess (scripts/_contract.py:799)
- An inventory of where the code starts another program, not a verdict on this row: whether each one runs a fixed program or whatever it is handed takes a reading by hand.
Published because it was found. A finding is information about where the limits are, not a verdict that the software is unsafe.
What this does not cover
- Everything. Treat it as you would software from anywhere else.

Static scanned
- What it establishes
- Its published package, or for a hosted server its source repository at a recorded commit, was read file by file, without running it, by every check in our current scan.
- What it does not
- How it behaves when it runs, or anything the scan does not read yet: several rubric checks, the repository's history, and compiled code in folders named dist or build. For a hosted server, that the endpoint runs the code that was read. The ooruby Index sets out exactly what was read.
- Exactly what was read
- Version 2.8.0, the file with digest sha512-aTKBxfM12H1UOHzXDK//+eYYgPavuWNMKYWPdsykaGGi0xzolGA5OlfaGYlCH9i/FOtOjDN4m1sGPc2Yhacxig==, as the registry publishes it. A published version cannot be replaced, so this names the same bytes for anyone who checks.
- Authentication
- Runs locally. No hosted endpoint is listed for this package. You run it on your own machine, so there is no endpoint of ours to authenticate against.
Adding it
Run it with:
npx -y ffmpeg-skill@2.8.0Pinned to 2.8.0, which is the version the findings above were found in. Drop the version to take whatever is newest, and the report on this page stops describing what you installed.
