Smart Dubber – Actor (encelade-conseil/multilingual-dubber)
Smart Dubber is an AI-powered, pay-per-event (pay-as-you-go) Apify Actor that turns any public audio or video into natural-sounding dubs in 29 languages using ElevenLabs (11Labs).
It preserves original tone and emotion, delivering high-quality, watermark-free outputs in MP4, WAV, AAC, or MP3 formats.
Current limitation: Dubbed files are limited to 30 minutes (1 800 s) per language.

🔧 How it works
- Submit a public HTTPS URL, a Google Drive share link, or a Key-Value Store key URL.
- Choose one or more target languages and an output format (AAC, WAV, MP3 or MP4).
- Wait until the process is complete.
It can take several minutes or more depending on the duration of the media and the number of languages to be dubbed. - When the run is complete, check the Dataset to download the result files for each language.
⚠️ Larger input files will result in longer processing times.
📥 Input Schema
Example:
{ "mediaUrl": "https://example.com/video.mp4", "targetLanguages": ["fr", "es", "ja"], "outputFormat": "MP3" }
| Field | Required | Notes |

Limitations
- Output length per language: Every dubbed file generated by the actor is guaranteed to be no longer than 30 minutes (1 800 seconds) for each target language.
- Maximum source size: Media files larger than 1 GB are rejected.
- Supported languages: Only the ISO language codes listed in the input form are accepted; any other code will be ignored.
- Network accessibility:
mediaUrlmust be a direct HTTPS link or an Apify KV-store record URL. Links that require sign-in are not supported. - Resource usage: The temporary disk space inside the container is roughly twice the RAM you allocate, so very large raw files may exhaust this space during processing.
Concurrency & Queueing
-
Maximum parallel runs: The actor will execute up to 5 runs in parallel.
When more than five runs are triggered at the same time, the additional runs are automatically placed in a queue and start as soon as a slot frees up. -
Impact on waiting time: If many users launch the actor concurrently, your run may spend some time in the queue before it actually starts.
Please be patient—the queue processes runs in the order they were received.
🛠️ Troubleshooting
| Issue | Possible Fix |
|---|---|
| Dataset row has error | Check that your mediaUrl is publicly accessible and in a supported format. |
| File missing for one language | That language may have failed to dub — check the outputs[].error field. |
| Run seems slow | Large input files or peak-time usage may cause delays — consider splitting media. |
