Translating Videos and Audio
Updated Nov 6, 2026
The fastest way to translate a Master Library video course is to translate its caption files: every video course includes an SRT and a VTT caption file for each lesson, so you translate the text, keep the timestamps and upload them as subtitles. For a full voice in another language, translate the video scripts (included as a Word file) and re-record the narration or use an AI dubbing tool.
What you start with
| Product | Files that help with translation |
|---|---|
| Video course | Captions folder (SRT and VTT per lesson), Video Scripts (.docx), workbook, checklist and prompt pack in Word |
| Audio | The audio files (M4A or WAV) and artwork. Make a transcript first with a tool such as Descript or Otter.ai |
Option 1: Translated subtitles (easiest)
- Open the lesson's
.srtfile. It's plain text: a number, a timestamp line and the words. - Translate only the words, and leave the numbers and timestamps exactly as they are. DeepL and Google Translate accept text files; ChatGPT or Claude can translate SRT if you ask them to keep the timing lines unchanged.
- Save it with the language in the name, for example
01 - Lesson name.es.srt. - Upload it as a subtitle track on YouTube, Vimeo or your course platform, or burn it into the video with an editor such as CapCut or VEED.
- Watch each lesson once with the subtitles on to check timing and line length.
Use the .vtt files if your platform or web player asks for WebVTT.
Option 2: A new voiceover
- Translate the Video Scripts Word file.
- Record the new narration yourself, hire a native-speaking voice actor, or use an AI voice.
- Replace the original audio track in your video editor and adjust any timing.
- Translate the captions too, so viewers can read along.
Option 3: AI dubbing
Tools such as HeyGen, ElevenLabs and Rask AI translate the speech and generate a voice in the new language, some with lip-sync. Quality varies by language and speaker, so watch every lesson before you publish. Only clone a voice you own or have permission to use, and check each tool's terms for commercial use.
Translating audio products
- Make a transcript (Descript, Otter.ai, or upload to a transcription tool).
- Translate it.
- Record or generate the new audio and edit it in Audacity or GarageBand.
- Or turn it into a video: a still image or slides with translated subtitles over the original audio.
Don't forget the extras
Translate the workbook, checklist and prompt pack too (they're in Word, see Translating text-based products), plus the course title, cover and lesson names.
Quality checks
- Subtitles: no more than two short lines on screen at once, and in sync with speech.
- Voiceover: matches the pace of the visuals, with no long silences.
- A native speaker watches at least the first lesson.
