Lip-sync many videos at once with sync. labs (sync.so), from a CSV, spreadsheet, folder or list. Pairs each video or avatar with its own audio or script, quotes the whole run, works within the plan's concurrency limit or uses the Batch API, resumes safely without paying twice, and collects every output. Use for bulk or batch lipsync of supplied audio or scripts, personalized video at scale (one video per lead, customer or recipient name), ad and creative variants, many voiceovers onto one…

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

# Lipsync many videos

Delivers one MP4 per row of the user's list, plus a results table that maps each row to its output.

If no sync. tools are available and there's no `SYNC_API_KEY`, follow [references/connect.md](references/connect.md) first.

## 1. Build the manifest

Turn whatever the user gave you (a CSV, a spreadsheet, a folder of files, "this video with each of these 30 audio files") into a CSV in the working directory, one row per output video:

| Column | Meaning |
| --- | --- |
| `id` | A unique, stable row name, such as `lead-042` or `es-ad1`. It names the output and keys retries. |
| `video` | A local path, `https://` URL or sync. asset ID. Use `image` instead for a still picture (sync-3). |
| `audio` | A local path, URL or asset ID. Leave it empty when the row uses `script`. |
| `script`, `voice_id` | The words and a voice from `voices_list` (or `GET /v2/voices`), when there's no audio. |
| `sync_mode` | Optional: `bounce`, `loop`, `cut_off`, `silence` or `remap`. |

How to install

The exact contents, by fingerprint

mdr add synchronicity-labs/skills/batch-lipsync@sha256:1c207d521664b858

The line at the top of this page pins the label git:20261105.77971a9, 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.
