Use when the user has 2+ video / audio recordings of the same event captured by different devices (cameras, phones, separate audio recorders) and wants them aligned to a single common timeline. Outputs only a lightweight `.sync.json` sidecar per input — original files are never re-encoded. Triggers — "多机位同步", "对齐这几个机位", "match camera timelines", "sync these angles", "audio drift between cameras", "separate audio recorder", "Riverside / Zoom recording that needs to line up".
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# wjs-syncing-multicam Compute a single time offset for each multi-source recording of the same event using audio cross-correlation, and emit a `.sync.json` sidecar next to each original. **Originals are never modified, copied, or re-encoded.** Downstream tools use `-itsoffset` to apply the offset at consume time. ## Setup & commands The implementation lives in the open-source **`polysync`** pip package (<https://pypi.org/project/polysync/> · <https://github.com/jianshuo/polysync>) — this skill no longer ships its own scripts. Ensure it's installed, then drive it via its CLI: ```bash python3 -m pip install -U polysync # needs ffmpeg/ffprobe on PATH polysync sync REFERENCE SOURCE # align SOURCE to REFERENCE, write sidecars polysync sync REFERENCE SOURCE --partial # source covers only part of the session polysync verify REFERENCE SOURCE SOURCE.sync.json # independent residual check ``` Run one `polysync sync` per non-reference angle (reference first, same reference each time). The sections below document the algorithm, the sidecar schema, and the gotchas baked into the package — read them to interpret output and choose flags. …

How to install
mdr add jianshuo/claude-skills/wjs-syncing-multicam@sha256:f9d116f4c6da5203The line at the top of this page pins the label git:20260525.a1d9235, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
