YouTube deleted auto dub can't be republished: keep your own file

YouTube's help page says that once you delete an automatic dub, it is no longer available and you cannot republish it. If you only want a dub hidden, choose Unpublish, which the same page lists beside Publish and Delete. If you want a dub you can always bring back, make it yourself and keep the audio file.

This post uses YouTube's Use automatic dubbing page, read on 2026-10-03, plus Sume's audio docs for the part YouTube leaves with you.

What does YouTube let you do with an auto dub?

The page says creators can preview dubs, review transcripts and then Publish, Unpublish or Delete them in the Languages section of YouTube Studio; it names desktop for dub management. On Android, the Studio app has an Automatic dubbing setting under Content, where you can turn the feature on or off and choose Publish manually so you review before anything goes live.

The page also lists what makes a video ineligible: longer than 120 minutes, no speech or only music or very little speech, an unsupported or undetectable original language, speech that is too fast, and copyrighted content. It labels lip sync as an experimental feature with early access for select channels.

Why does Delete matter more than it looks?

Delete is the only action in the list that cannot be undone. A reviewer cleaning up a Languages page may delete a dub that is slightly wrong, planning to republish a corrected one. The page says that cannot happen, so the only route back is a fresh generation, which may sound different from the one viewers already heard.

Treat Delete as a last step, not a cleanup tool. Unpublish while you decide, and write down which languages were live before you touch anything.

How do you keep a dub you can always reuse?

A YouTube auto dub lives inside YouTube. A dub you make as audio can live in your workspace. Timeline audio joins Sume-hosted audio into one gapless file and returns a durable media.sume.com URL with timings. The produced audio is capped at 1800 seconds, and the job costs $0.01 flat per its page.

Keep the wav output when you might join or edit the file again; the page says mp3 re-adds priming padding at every edge. Store the URL next to the video id and language in your own sheet.

curl -X POST https://api.sume.com/v1/timeline-1.0/audio \
  -H "Authorization: Bearer $SUME_API_KEY" \
  -H "Content-Type: application/json" \
  -H "Idempotency-Key: dub-es-master-001" \
  -d '{"operation": "concat", "parts": [
       {"url": "https://media.sume.com/artifacts/artf_demo/line1.wav"},
       {"url": "https://media.sume.com/artifacts/artf_demo/line2.wav"}]}'

What should you record before deleting anything?

A short log makes a deleted dub recoverable in practice, even though YouTube cannot restore it. You are keeping the inputs, not the file.

• The video id, the language and the date the dub went live.
• The transcript YouTube showed you for review, copied as text.
• Your own dub file URL, if you made one, and the voice settings used.
• Whether lip sync was on, since the page calls it experimental.

When is dubbing it yourself worth the work?

When the wording must be exact, when you need to republish later, or when the video is over YouTube's 120-minute eligibility line. Sume has no one-call dubbing route; you chain detach, speech-to-text, your translation and speech jobs. For a short video that is minutes of work, and every file stays yours.

When a loose dub is good enough and you never plan to edit it, YouTube's automatic option is free to try on eligible videos. Just remember that Delete means start over.
