How to Translate a Video – Step-by-Step Guide

What translation used to require (and why no one wants that anymore)

Until recently, translating a video meant:

• Having the script translated
  
• Hiring a professional voice actor
  
• Booking a studio
  
• Recording, editing, mixing
  
• (Maybe) syncing the lips manually
  
  

It was expensive.
It took weeks.
And it didn’t scale.
One video was a full-blown production. Ten videos became a nightmare.

How it works today – fast and fully online

Thanks to AI platforms like Dubly.AI, video translation is now:

• Fully online
  
• Voice actor–free
  
• Studio–free
  
• Fast, scalable, and affordable
  
  

Here’s exactly how it works.

‍

 Step-by-step: How to translate your video

1. Upload your video

Go to the platform, upload your video file (MP4 works best).
Make sure the audio is clear – less background noise = better results.
If possible, avoid background music or text baked into the visuals.

‍

2. Choose your target language(s)

Decide which language(s) you want the video translated into. For example:

• German → English
  
• German → Spanish
  
• German → French
  
  

You can select multiple languages at once – the platform handles them in parallel.

‍

3. Configure your settings

Before translation starts, you can fine-tune how it works:

• Audio optimization: Removes background noise, levels out volume
  
• Speaker detection: For multi-speaker content like interviews or panels
  
• Custom vocabulary: Upload brand terms, product names, or specific lingo
  
• Custom prompts: Define tone, wording preferences, or context for better results
  
  

You stay in control. You can edit and adjust everything later on.

‍

4. Start the translation

Now the AI gets to work:

• It analyzes the full video – not just line-by-line
  
• It understands the context, tone, and flow
  
• It generates a natural-sounding voiceover in the target language
  
  

You can also choose to preserve the original speaker’s voice – just speaking in another language.

‍

5. Preview & adjust

You get a preview of the translated version before it’s finalized.

• Don’t like how something sounds?
  
• Want to swap out a word or phrase?
  
• Prefer a different tone?
  
  

No problem – you can make changes directly.
And if you want an extra layer of polish, Dubly offers Native Speaker Control: a real human double-checks the output.

‍

6. Generate lip-sync

Once the translation is ready and approved, the final step is syncing the lips.

The system analyzes the face in the video and adjusts the lip movements to match the new voice track – even from side angles or in fast dialogue scenes.

Result: it looks like the speaker is actually speaking the new language.

‍

7. Download and publish

Download your final video and use it wherever you want:

• YouTube
  
• LinkedIn
  
• Your website
  
• Internal platforms
  
• E-learning systems
  
  

No extra editing needed. Just click, download, publish.
