AI Video Translator

AI Video Translate converts the speech in a video into 150+ languages while preserving the original speaker's voice character, speaking rhythm, and lip sync alignment. Upload an MP4, WebM, or MOV file (up to 200 MB and 5 minutes), choose a target language and quality mode, and the tool returns a fully dubbed MP4. Credits are charged by video duration, not file size.

Standard mode vs. High Quality mode

A practical workflow: run Standard first to check that the translation content is correct and the overall timing works, then reprocess with High Quality for the release version. The quality difference is most noticeable on videos with multiple speakers, low source audio quality, or close-up talking-head shots where lip sync is clearly visible. For a single clear speaker on a clean recording, both modes often produce comparable results.

What affects voice naturalness in the output

The dub quality depends on how well the source audio can be isolated and analyzed:

• A clean voice recording with minimal background noise or music produces the best result
• Speakers facing the camera with the mouth visible help with lip sync alignment
• Moderate speaking pace — not too fast, not too slow — tends to produce more stable output
• Single-speaker videos are easier to process than multi-speaker cross-talk

Proper nouns, brand terms, and abbreviations are common translation trouble spots. Always review these specifically before publishing. Existing on-screen subtitles are not automatically replaced — handle those separately in a video editor.
