What it does

Storyboard Av Mix is an agent skill from godot-fun/gai. Muxes per-shot storyboard video with Chinese and English voice-over by retiming video to match VO duration (setpts), writing Video-Chinese/ and Video-English/ (matched by shot id 01, 02, …). Use when the user wants storyboard A/V mix, storyboard A/V mix, VO dubbing mix, video retime to audio, Video-Chinese, Video-English, bilingual VO on cut video, or batch mux Video/ + Chinese/ + English/.

Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Media & Creative, covering Comics and storyboards, Text to speech and voice and Translation. The repository describes itself as: A lightweight AI agent and skill workflow framework built with Godot. The licence is MIT.

When your agent uses it

The user wants storyboard A/V mix
Storyboard A/V mix
Video retime to audio
Bilingual VO on cut video

Example prompts

“Use the storyboard-av-mix skill to mux per-shot storyboard video with Chinese and English voice-over by retiming video to match VO duration…”
“/storyboard-av-mix”

Requirements

Python 3

Workflow steps

7 steps, taken from the first numbered list in SKILL.md.

VO timing is immutable. Never stretch, shrink, pad, trim, or atempo the voice-over. Duration of the VO file is the master clock.
Video serves audio. Only change video duration (FFmpeg setpts) so it equals that shot’s VO length, then mux.
Drop all audio from the source video; replace with the VO track. Prefer -c:a copy; if the container cannot hold the VO codec (e.g…
Do not downgrade video. setpts requires a re-encode, but match the source: codec family (H.265 Main10 when source is 10-bit HEVC)…
Match shots by filename stem (01.mp4 ↔ 01.wav).
Batch only via .ai/storyboard-av-mix/mix.py — do not hand-write FFmpeg mux/retime commands.
Never overwrite inputs under Video/, Chinese/, or English/.

What it can do on your machine

Read from SKILL.md and the folder at commit 6394686. 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
Shell commands in SKILL.md call:
- python
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

Storyboard Av Mix loads about 1.1k tokens when it runs. Until then it costs about 103 tokens; SKILL.md has 415 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~103
When it runs · the whole SKILL.md, loaded when a task matches: ~1.1k

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.

Storyboard AV Mix

Take a work directory with per-shot video and bilingual VO. For each shot, retime the video to the full VO duration (audio master), drop original video audio, mux, and write language-specific folders.

Input	Path
Shot video	`<root>/Video/<shot-id>.*`
Chinese VO	`<root>/Chinese/<shot-id>.*`
English VO	`<root>/English/<shot-id>.*`

Output	Path
Chinese mux	`<root>/Video-Chinese/<shot-id>.<video-ext>`
English mux	`<root>/Video-English/<shot-id>.<video-ext>`

Rules

When this skill applies, read and follow skill-dependency-manager — run scripts as documented, install missing tools into .dependency/.

VO timing is immutable. Never stretch, shrink, pad, trim, or atempo the voice-over. Duration of the VO file is the master clock.
Video serves audio. Only change video duration (FFmpeg setpts) so it equals that shot’s VO length, then mux.
Drop all audio from the source video; replace with the VO track. Prefer -c:a copy; if the container cannot hold the VO codec (e.g. WAV→MP4), encode AAC without changing length.
Do not downgrade video. setpts requires a re-encode, but match the source: codec family (H.265 Main10 when source is 10-bit HEVC), pix_fmt, bitrate, color tags, and HDR side data (mastering display / MaxCLL). Copy container + video-stream metadata from the source clip.
Match shots by filename stem (01.mp4 ↔ 01.wav).
Batch only via .ai/storyboard-av-mix/mix.py — do not hand-write FFmpeg mux/retime commands.
Never overwrite inputs under Video/, Chinese/, or English/.

Quick Start

From project root:

bash

.dependency/python/python .ai/storyboard-av-mix/mix.py path/to/<root>

Single language:

bash

.dependency/python/python .ai/storyboard-av-mix/mix.py path/to/<root> --lang chinese

Per shot / language the script:

Probes VO duration (source of truth) and video duration
Applies setpts=PTS*(vo_dur/video_dur) — stretch or compress video only (plus short freeze-tail so video ≥ VO)
Muxes with -shortest so container duration == VO duration
Writes <root>/Video-Chinese| or Video-English/ / <shot-id>.<same-ext>

Layout

<root>/
  Video/
    01.mp4
    02.mp4
  Chinese/
    01.wav
    02.wav
  English/
    01.wav
    02.wav
  Video-Chinese/     # written by this skill
    01.mp4
    02.mp4
  Video-English/
    01.mp4
    02.mp4

Typical <root> is a storyboard-tts audio dir that also has a sibling or nested Video/ of cut clips — confirm the folder that contains Video/, Chinese/, and English/.

Common Flags

Flag	Notes
`root`	Work dir with `Video/`, `Chinese/`, `English/`
`--lang`	`both` (default), `chinese`, `english`

Existing outputs are overwritten. Missing VO for a language → skip that job with a warning. Missing video → skip shot.

Agent Notes

Audio first: if durations disagree, change video, never VO.
Prefer one mix.py run for the whole board.
Re-encode must preserve source quality tags (Main10 / HDR / bitrate) — never force 8-bit H.264.
Chat summary: <root>, jobs done / skipped, paths to Video-Chinese/ and Video-English/.
Upstream VO usually from storyboard-tts; this skill does not synthesize speech.
Missing Python/FFmpeg → populate .dependency/ per skill-dependency-manager, retry same command.

Tests

From repo root:

bash

.dependency/python/python .ai/storyboard-av-mix/test_mix.py

storyboard-tts — bilingual VO under Chinese/ / English/
storyboard — source markdown
