A whole lesson set. One organised delivery.

Batch translate up to ten SRT/VTT course lessons into selected languages. Retry failed pairs, review the results and download organised subtitle ZIPs.

How it works

  1. Add up to ten lesson subtitle files and choose up to four languages.
  2. Follow each lesson/language result and retry unfinished translations.
  3. Download SRT, VTT or both, with language folders and a completion report.

Frequently asked questions

What happens when one lesson fails?

Each lesson/language pair is applied only when all its caption batches succeed. Completed pairs are retained when another fails or you cancel. Retry unfinished pairs without repeating successful ones, or explicitly download a partial delivery.

Does batch processing upload my videos?

No videos are needed. Source subtitles and project files stay on your device. When you translate, lesson text, course names and the glossary are sent for processing.

What are the preview limits?

A course supports ten lessons, four target languages and 100,000 source-text characters. Each source file is limited to 1 MB and 2,000 captions. Larger courses should be split into projects.
