name: board-sync
description: Animate explainer boards to the presenter's voice. Takes the board HTMLs from Claude Design (04-boards), the final-cut WAV and its words.tsv, the marked script and the board brief; makes every element land on its spoken word; renders one clip per board and a full-length board-track.mp4; checks itself (qa-report.md with contact sheets); and writes the editor timeline for DaVinci Resolve (FCPXML) and Premiere (FCP7 XML) with the camera in the bottom-right zone. Step 5 of the explainer pipeline. Use when the editor says "animate the boards", "sync the boards to his voice", "board video", "render the boards", "build the editor timeline", re-runs one board after a fix, or asks why a board lands early, sits static or covers the camera zone. Runs end to end on Windows and Mac with one setup command (Python via uv, ffmpeg, the installed Edge or Chrome).

# board-sync

Step 5 of the explainer pipeline: the boards from Claude Design plus the final-cut audio become a board video where
every element appears on the word that names it, and a timeline the editor opens in DaVinci Resolve or Premiere.

## What it needs (the video's folder)

```
02-cut\<name> - final cut.wav            the final audio (the only sound in the video)
02-cut\<name> - final cut words.tsv      word timings from your editor (if missing, board-sync transcribes the WAV)
02-cut\<name> - final cut.mp4            optional: the 4K cut, only to name it in the timeline
03-board-brief\script-marked.md          the script with [▸ SLIDE n · title] and [CAMERA] markers
03-board-brief\brief.md                  the board brief (builds, anchors, numbers' roles, fillers)
04-boards\NN-Name.html + assets\         one HTML per board from Claude Design, with its assets folder
```

## Setup (once per computer)

Windows, in PowerShell inside this skill's folder:

```
powershell -ExecutionPolicy Bypass -File .\setup.ps1
```

Mac: `bash setup.sh`. Both are safe to run again. They install uv, a Python 3.12 environment with the packages,
ffmpeg, and check for Edge or Chrome (Playwright's own Chromium is downloaded only if neither is there). The first
transcription, if one is ever needed, downloads the speech model (about 1.6 GB). The setup ends by printing the exact
run command for this computer.

## Run (from the video's folder)

```
& "<skill>\.venv\Scripts\python.exe" "<skill>\board_sync.py" --boards "04-boards" --wav "02-cut\<name> - final cut.wav" --words "02-cut\<name> - final cut words.tsv" --script "03-board-brief\script-marked.md" --brief "03-board-brief\brief.md" --out "05-board-sync\out"
