Frequently asked questions

What do I need to use it?
Node.js 18+ and a Perso Dubbing API key. Install the skill, then just say "dub this video for me." → Get an API key
How do I register my API key?
On the first run a browser page opens — sign in and click once, and your key is issued and stored on this machine, encrypted. Nothing to copy. If no browser can open, a key file opens instead: paste only your API key into it and save (it is encrypted and the file is deleted). Never paste the key into the chat. Manual check: npm run key:check.
Does it cost money?
The skill's code is free (MIT), but the dubbing runs through the Perso API, which bills credits. Signing up includes a 30-second free trial, and subtitle translation, styled captions, and clipping are free without an account.
What can I feed it?
A local file, a local folder, or a URL (YouTube, TikTok, Google Drive). Oversized or very long videos are automatically split, processed, and merged back together.
Can it dub into several languages, or process many files at once?
Yes. Put multiple languages in one command (--target en,ja,zh) — the source is uploaded and split once, then reused per language. You can also mix multiple files, folders, and URLs in a single run.
Where are my results saved?
Next to the source video by default, or in the folder you pass with --out. Every run is also a project in your Perso portal (https://perso.ai/en/workspace/vt), where you can re-download it or get other formats.
What is lip-sync?
It matches the mouth movements to the dubbed audio. It runs after dubbing, works on video only, takes considerably longer, and costs extra credits. Add --lipsync.
What is audio separation?
It splits the source into voice / background / sub-background tracks — no dubbing involved. Add --separate.
Can it make subtitles (SRT) instead of dubbing?
The /srt skill extracts original-language subtitles from a video/audio/URL via Perso's speech-to-text. If you also want them translated, ask for the SRT along with the languages you want.
It stopped midway (out of credits, a crash, or a killed shell). Now what?
Progress is saved to a state file throughout the run (*.dubresume.json for /dubbing, *.srtresume.json for /srt). Re-run the printed --resume "<state-file>" command to finish only the remaining parts — completed parts are skipped and never re-billed.
I ran out of credits. How do I top up?
The skill can generate a Stripe payment link (subscribe, change plan, or buy credits, depending on your plan). You open the link and pay yourself — the agent never pays on your behalf. After topping up, resume with the printed --resume command.
Can I dub without saving a local file?
Yes, for a single (unsplit) video: add --no-save. The result stays in your Perso workspace and is not downloaded. Split videos are still saved normally, because the merged file needs a local download.
node was not found — what do I do?
The skill needs Node.js 18+. Check with node -v; install the LTS from https://nodejs.org, or simply ask the agent to install it for you, then retry.
How do I update the skill?
npx perso-dubbing@latest, or in the Claude Code plugin: /plugin update perso-dubbing.
What data does the skill collect?
Usage events only — which action ran, whether it succeeded, coarse counts, app version, and OS — tagged with a random per-install ID and your workspace number. Your API key and your media are never included.
