How to Use AI for Video Translation with DupDub

Introduction

Step 1 – Upload Your Video

• Upload your video file: You can either upload a pre-downloaded file from your device or paste a video URL from supported platforms.
• Supported formats: DupDub accepts multiple file formats including MP4, MOV, and more.
• Length limit: Each video must be 10 minutes or shorter.

Step 2 – Select Original and Target Languages

• Auto-detect or manually choose the original language: DupDub can identify the language spoken in your video, or you can set it manually. If you're unsure, select “Unknown.”
• Pick your target language: Choose from over 30 supported languages, including Chinese, English, French, Arabic, and more.
• Additional settings:
  • Enable lip sync to match mouth movements with the translated audio
  • Choose to remove background music for better clarity
  • Replace existing subtitles with translated ones

Step 3 – Proofread and Export Your Translation

• Translation mode: You can choose to proofread the translation first or generate the video directly. If you're confident in the AI output, go ahead and skip proofreading to save credits.
• Proofreading workflow:
  • Edit translated text in the left panel
  • Adjust or switch voiceovers by clicking voice icons
  • Tweak subtitle settings in the right panel
  • Click "Generate all voices" when finished
• Export options: Once satisfied, hit Export in the top right corner to download your video

Step 4 – Final Adjustments and Download

• Edit after export: Open your project and click “Edit” to refine subtitles, adjust timing, or replace audio.
• Download options: Use the Download button to save the video locally
• Manage files: Delete or rename the video directly from your project dashboard

Final Tips for Accurate AI Video Translation

• Use clear audio sources: Videos with minimal background noise and distinct speech produce the best transcription and translation results.
• Preview and refine your translation: Always double-check the translated subtitles and voiceovers for tone, meaning, and natural flow.
• Enable lip sync when needed: This is especially helpful when translating talking avatar videos or any footage with a visible speaker.
• Small improvements in clarity and emotion can make a big difference in how your global audience connects with your video.
