Upload a video you own or are authorized to localize, let the workflow detect its spoken language, then generate an English transcript, subtitles, and optional voiceover. Review names, timing, and pronunciation before exporting the English version.
Yes. Choose English subtitles, English dubbing, or both. The workflow can preserve background audio, assign voices to speakers, and keep translated captions aligned with the English narration.
Remove source-language captions from the pixels first so old text does not sit underneath the English subtitles. This creates one clean master for dubbing, re-captioning, and future localization.
A good English version changes more than words. It clears conflicting source text, preserves meaning and speaker tone, and gives the final subtitles enough room to stay readable.
Match the output to how viewers will watch and how your team plans to publish.
Keep the original voice and add timed English captions for accessibility, silent autoplay, or a faster localization pass.
Replace spoken audio with an English voice while preserving pacing, speaker roles, and the energy of the original delivery.
Pair English audio with readable captions for maximum comprehension across feeds, courses, presentations, and embedded players.
Review names and terminology, then reuse the approved English transcript for captions, articles, notes, or translation QA.
