FAQ

How does Luxembourgish dubbing work?

You upload an MP4 file. The soundtrack is transcribed, translated into Luxembourgish, then re-synthesized with a voice per character and burned-in subtitles. The result is a ready-to-share MP4.

How much does it cost?

A preview of the first 15 seconds is free. The full version is billed pro rata, from €2/min, payable online without creating an account.

Which files are accepted?

MP4 files up to 100 MB. For a larger video, reduce its resolution or duration before uploading.

How long does processing take?

Processing is heavy and asynchronous: videos are handled one at a time. You can track progress in the jobs list.

Are my files kept?

No. Results are deleted automatically 4 hours after processing finishes.
