Playground

HeyGen Video Translate: AI video translation into 70+ languages and 175+ dialects with no voice actors or dubbing. Fast, accurate, easy to use at $0.0375/sec. Ready-to-use REST API, no coldstarts, affordable pricing.

Features

HeyGen Video Translate is a powerful AI-powered video translation and dubbing model that automatically translates spoken content in videos into different languages — complete with lip-sync and natural voice cloning. Transform your videos for global audiences without reshooting.

Why It Stands Out

• Full video translation: Automatically translates speech and generates new audio in the target language.
• Lip-sync technology: AI adjusts lip movements to match the translated audio for natural-looking results.
• Voice cloning: Preserves the original speaker’s voice characteristics in the new language.
• Multi-language support: Translate into English, Spanish, French, Hindi, Italian, German, Polish, Portuguese, Chinese, Japanese, Dutch, and more.
• Simple workflow: Just upload a video and select your target language — no manual dubbing required.

How to Use

4. Preview and download the translated video.

Best Use Cases

• Global Content Distribution — Localize marketing videos, ads, and promotional content for international markets.
• E-learning & Training — Translate educational videos and courses for multilingual audiences.
• Social Media Expansion — Reach new audiences by translating viral content into multiple languages.
• Corporate Communications — Distribute internal videos and announcements across global teams.
• Entertainment & Media — Dub interviews, documentaries, and video content for foreign markets.

Pricing

Total cost = duration of video (in seconds) × $0.0375

Examples

• 30s video → 30 × $0.0375 = $1.125
• 60s video → 60 × $0.0375 = $2.25
• 5 min (300s) video → 300 × $0.0375 = $11.25
• 10 min (600s) video → 600 × $0.0375 = $22.50

Pro Tips for Best Quality

• Use videos with clear speech and minimal background noise for optimal translation accuracy.
• Single-speaker videos typically produce better lip-sync results than multi-speaker content.
• Ensure the original audio is high quality — translation quality depends on accurate speech recognition.
• For best lip-sync, use videos where the speaker’s face is clearly visible and well-lit.

Notes

• Ensure uploaded video URLs are publicly accessible.
• Processing time varies based on video duration and current queue load.
• Please ensure your content complies with usage guidelines.
