HeyGen Video Translate API: AI-Powered Video Translation via API
HeyGen's video translation technology lets you dub and translate videos into multiple languages with realistic lip-sync, voice cloning, and facial movement matching. Renderful provides API access to HeyGen's translation capabilities — so you can integrate AI-powered video translation into your application with a single API call.
What is HeyGen Video Translate?
HeyGen Video Translate is an AI-powered video translation service that dubs videos into different languages while preserving the speaker's natural appearance. Unlike traditional dubbing, HeyGen uses AI to automatically adjust lip movements to match the translated audio, creating a seamless and natural-looking result.
Key capabilities include automatic lip-sync adjustment, voice cloning that preserves the speaker's vocal characteristics in the target language, facial movement matching for natural expressions, and support for a wide range of languages. The result is a translated video that looks and sounds as if the speaker is natively speaking the target language.
How to Use the HeyGen Video Translate API
With Renderful, translating a video with HeyGen is as simple as making a single API call. Sign up for an API key, then send a POST request with your video URL and target language. Here's a working example:
curl -X POST https://api.renderful.ai/api/v1/generations \
-H "Authorization: Bearer YOUR_API_KEY" \
-H "Content-Type: application/json" \
-d '{
"model": "heygen/video-translate",
"input": {
"video_url": "https://your-bucket.s3.amazonaws.com/video.mp4",
"target_language": "es"
},
"webhook": "https://your-app.com/webhook"
}'The API is asynchronous — your webhook will receive the translated video once processing finishes. You can also poll the generation status endpoint for progress updates.
