How to dub a video with AI

  1. Add your videoUpload an MP4, MOV or WEBM file up to 60 MB, or paste a direct video link that ends in .mp4, .webm or .mov. Short clips dub fastest.
  2. Set the source languageTell the tool which language is spoken in the video: English, Hindi, Spanish, French, Portuguese, Italian, German, Russian, Japanese, Korean, Chinese or Arabic.
  3. Choose the dub languagePick one of 9 languages: English (US), English (UK), Spanish, French, Hindi, Portuguese (Brazil), Italian, Japanese or Chinese.
  4. Pick a voice (optional)Leave the voice on Automatic and the AI picks a natural native voice for that language. Or open More options to choose a specific voice and set the speech speed from 0.8x to 1.25x.
  5. Generate the dubPress Generate Dub. When it is ready, preview the dubbed video and download it as an MP4.

Why US creators and businesses dub their videos

Spanish is the second most spoken language in the United States, and huge audiences on YouTube watch in Spanish, Hindi and Portuguese. A dubbed version lets the same content work twice. Common uses:

  • YouTube channels publishing a Spanish or Hindi version of their most popular tutorials.
  • Online course creators offering a translated lesson for international students.
  • Shopify and Amazon sellers localizing a product demo for customers in Mexico, Brazil or India.
  • Churches and nonprofits sharing announcements and messages with Spanish-speaking members of their community.
  • HR and training teams making onboarding videos easier to follow for bilingual staff.

AI dubbing is a fast first step. For high-stakes content, such as legal, medical or safety training, have a fluent speaker review the dub before publishing.

ResultDubbed video, downloadable as MP4

Short clips finish fastest. For a longer video, trim it into chapters and dub each one.

Example: one product video, three markets

Say you sell handmade leather wallets on Shopify and have a two-minute English demo video. Here is a simple afternoon workflow:

  1. Upload the MP4 and set the source language to English.
  2. Dub it into Spanish with the Automatic voice. Watch it once and check that the speech still fits each product close-up.
  3. Repeat for Portuguese (Brazil) and Hindi. If a voice feels too fast or slow, change the speech speed under More options.
  4. Upload each version to YouTube as an unlisted video, or embed it on a translated product page.

The same approach works for a real estate walkthrough, a recipe video or a software tutorial: one recording, several languages.

Tips for a better AI dub

  • Start with clear speech. Single speaker videos with quiet backgrounds dub much better than noisy street interviews.
  • Keep it short. Files can be up to 60 MB, but short clips dub fastest. Trim intros and outros, or split longer videos into parts.
  • Set the right source language. Picking the language actually spoken in the video gives the most accurate translation.
  • Adjust the speed. Spanish and French often run longer than English. If the dub feels rushed or slow, try a speed between 0.8x and 1.25x.
  • Label it. Viewers appreciate a short note such as “AI-dubbed Spanish version” in the title or description.
