HOW TO TRANSLATE AN MP4 VIDEO

Translate an MP4 video, then review what your audience will see and hear.

This is a full video-translation workflow for an MP4 with spoken audio. It is not a general file converter.

  1. 1

    Upload an MP4 video

    Add an MP4 with spoken audio. The workspace also accepts MOV and WebM files.

  2. 2

    Choose the audience language

    The video audio language is detected automatically. Choose the language your audience needs next.

  3. 3

    Review the translation

    Check the transcript, translated lines, names, terminology, timing, and voice choice before export.

  4. 4

    Generate and export

    Create a localized video or download the subtitle and content files your workflow needs.

REVIEW BEFORE EXPORT

Make the new-language version clear before it leaves the workspace.

The detected transcript is a starting point. Review details that can change meaning for people watching the translated version.

  • Names, brands, and abbreviations that need one consistent spelling.

  • Product terms, numbers, dates, units, and calls to action.

  • Subtitle timing and line breaks while the original video is playing.

Standard translation for narration-led video.

Use standard translation for tutorials, screen recordings, product demos, and videos where the speaker is not continuously visible. It replaces speech without changing lip movements.

Lip Sync for visible speakers.

Use Lip Sync for interviews, presentations, and talking-head videos where the translated delivery should align with visible speech.
