What it does
Final Pass is an agent skill from GTKottman/mortiflix-oss. Check a rendered video before anyone else sees it: format, black or frozen frames, loudness, true peak, and a frame sheet to look at. Use before submitting any animatic or final, and before mfx step done on a build.
Its SKILL.md is about 610 tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file.
It sits in Media & Creative. The repository describes itself as: A motion design studio on your own machine: Claude makes the video step by step, you approve every stage. Bring your own Claude Code or API key. The licence is AGPL-3.0.
When your agent uses it
- Media & Creative work in your project
Example prompts
- “/final-pass”
Requirements
- Node.js
Workflow steps
3 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit aea9533. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships script files (JavaScript), which the agent can run.
Shell commands in SKILL.md call:
ffmpegnode
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Final Pass loads about 613 tokens when it runs. Until then it costs about 57 tokens; SKILL.md has 294 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

- Check a rendered video before anyone else sees it: format, black or frozen frames, loudness, true peak, and a frame sheet to look at. Use before submitting any animatic or final, and before `mfx step done` on a build.
Final pass
Two halves, both required: the script checks what a machine can, and you look at what it can't.
1. Run the checks
node .claude/skills/final-pass/qc.mjs out/final.mp4 --size 1920x1080 --fps 30 --duration 60--size,--fps,--durationcome from the brief (shape, length). Duration passes within 5%.- Loudness:
--lufs -14(web default) and--true-peak -1. Change them only if the brief names a platform with other targets. --end-holdwhen the video is meant to end on a still hold (a logo that settles): that stretch then passes and its length is reported. A frozen stretch anywhere else still fails.--allow-blackonly when black mid-video is designed (a dip to black between chapters). Say so in the check note.- It writes
checks/qc-<name>.jsonandchecks/<name>-sheet.png, and exits 1 on any FAIL.
Fix every FAIL and run it again. A frozen stretch can be a designed hold: then it's a pass, and the check's note says which hold it is.
2. Look
- The frame sheet. View
checks/<name>-sheet.png(about a frame a second). Every frame must make visual sense: nothing half-loaded, no placeholder text, no element stuck at a wrong position, nothing cut off at an edge. - Three full-size frames at the busiest moments:
ffmpeg -ss 12.5 -i out/final.mp4 -frames:v 1 checks/f-12.5.png. Read every word on them. - Listen through once on the waveform's loudest and quietest parts: no clicks, pops, distortion, or words swallowed by the music.
3. Report
Map the results onto the step's error checks (mfx checks <step>): frame-sheet and format from the script plus
your look, loudness from the audio lines. Keep the JSON and the sheet in checks/. Submit the frame sheet as a
second item with every final: the owner can scan it in a second.
Fixing loudness
Two-pass loudnorm on the mix, never on a file you've already normalized:
ffmpeg -i mix.wav -af loudnorm=I=-14:TP=-1.5:LRA=11:print_format=json -f null - # read the measured values
ffmpeg -i mix.wav -af loudnorm=I=-14:TP=-1.5:LRA=11:measured_I=..:measured_TP=..:measured_LRA=..:measured_thresh=..:offset=..:linear=true mix-14.wav© GTKottman, AGPL-3.0. Rendered from Markdown: HTML in the file is shown as text, images as links, and headings moved down two levels. Raw file
