Help everyone make their best videos with HeyGen

Tips & Tricks

In today’s global landscape, reaching diverse audiences through video content in multiple languages is essential. At HeyGen, we’ve created an advanced solution to help you translate and localize your videos with ease, leveraging cutting-edge technologies like machine translation, voice cloning, and lip-sync.

You start by uploading your MP4 video into HeyGen’s platform. Our machine translation engine automatically translates the spoken content into the target language of your choice. Then, using voice cloning technology, we ensure that the voice in the newly translated video mirrors the original speaker’s tone, cadence, and personality. Finally, our sophisticated lip-sync technology synchronizes the speaker’s mouth movements with the new language, making the entire video feel natural, as if it were originally recorded in that language.

The ~85% Challenge: Why Human Review is Crucial

While HeyGen’s machine translation technology can take your video ~85% of the way to a fully translated and localized version, there’s always a gap that requires human input. Even with the most advanced AI, certain nuances, cultural context, or technical terms may not translate perfectly. This is where human expertise becomes invaluable.

Customers often ask if HeyGen provides human translation services, but our focus is on the technology—we don’t offer human-in-the-loop translation. Instead, we empower you to complete the translation process by incorporating human review, ensuring the final video reaches 99% accuracy (because, let’s face it, no translation is ever truly perfect).

Human Review Made Easy: Upload and Edit Your SRT or VTT Files

To streamline this process, HeyGen allows you to upload your own SRT or VTT subtitle files, which can be edited directly within our platform. Our built-in proofreading studio is designed for collaboration, so you or your translator can make quick adjustments, ensuring every phrase, word, and tone is accurate.

We recommend that our customers contract their own translators to bridge that final 15%. These translators will review the machine-generated translation, refine the language, and ensure it aligns with the intended message and audience. HeyGen’s proofreading studio makes it easy for translators to collaborate with your team, review, and adjust the translations directly on the platform.

Final Thoughts: Combining Technology with Human Expertise

At HeyGen, we’re proud to offer a technology-first approach that allows you to take control of your multilingual video content. By combining our AI-powered machine translation with the expertise of human translators, you can ensure that your videos resonate authentically with audiences across the globe. Start transforming your video content today, knowing that HeyGen has you covered from the first translation to the final, human-approved polish.
