In today’s global digital world, creators and companies face a growing demand to localize video content. AI-powered translation and dubbing tools have emerged as powerful solutions—making it easier than ever to connect with global audiences without the heavy costs of traditional production.
Among the top players, AI Studios and HeyGen offer unique solutions for AI video translation and dubbing. This blog explores how each platform works, their strengths, and how to choose the right one for your goals.
AI Video Translation vs AI Dubbing: What’s the Difference?
Before diving into the platforms, it's important to understand two key concepts:
- AI Video Translation applies when translating videos made within AI platforms, often featuring avatars and scripts. This typically involves translating the script and on-screen text into other languages directly in the platform.
- AI Dubbing applies to real-world videos made outside the platform. The audio is transcribed and translated, and an AI-generated voiceover is created in the target language. Lip-syncing helps match the speaker's mouth movements.
Both platforms also support dubbing for videos with multiple speakers. The AI will automatically detect and differentiate each speaker, ensuring the translated voiceover remains natural and clear across the entire video.
AI Video Translation: How AI Studios and HeyGen Approach It
AI Studios: Built for Speed and Control
AI Studios offers two translation workflows:
- Individual Translation: Translate scripts and on-screen text for one language within the editor—ideal for precision and easy edits.
- Batch Translation: Export multiple language versions at once. This is faster for large projects, though any edits after export require re-synthesizing.
HeyGen: Manual, Slide-by-Slide Translation
HeyGen takes a more hands-on approach:
- Translate each slide manually, giving full control but requiring more effort.
- No batch or global translation features.
- On-screen text must be manually translated and updated.
While more manual, this approach offers flexibility for creators who want direct control over every slide.
AI Dubbing: Expanding Global Reach
AI Studios: Comprehensive Dubbing Tools and Accuracy
AI Studios offers dubbing designed for professionals:
- Supports 30+ languages.
- Proofreading, available in Team plans and above, lets users edit translated scripts before generating videos—ensuring natural, accurate translations.
- SRT upload, available at Team plans above, allows importing files with pre-timed text and dialogue. This speeds up the dubbing process by giving the AI precise timing cues.
- Supports multiple speakers in a video and automatically identifies each speaker for accurate dubbing.
HeyGen: Straightforward and Broad Language Support
HeyGen offers capable dubbing tools:
- Supports over 70 languages and 175+ dialects.
- Proofreading available from Team plans and above.
- SRT upload available from Team plans and above.
- Allows users to upload videos directly from a YouTube URL, making it easy to dub online content without needing local video files.
- Supports multiple speakers in a video and automatically identifies each speaker for accurate dubbing.
While both platforms offer similar dubbing capabilities, HeyGen’s broader language support and YouTube URL upload option make it a flexible solution for creators working with diverse and web-based content.
Which Platform Should You Choose?
When to Choose AI Studios:
- You want streamlined translation workflows, especially for videos created within the platform.
- You need batch translation and export for distributing multilingual content easily.
- You prefer editing translated scripts with proofreading before dubbing.
When to Choose HeyGen:
- You need dubbing across many languages and dialects (over 70 supported).
- You want the flexibility to dub videos directly from YouTube URLs without downloading them first.
- You are creating social media or avatar-driven content and prefer simpler translation steps.
- You are comfortable manually translating on-screen text and working slide-by-slide.
AI Studios and HeyGen both offer strong AI video translation and dubbing solutions. When it comes to AI Dubbing, the platforms are quite similar—both support proofreading, SRT upload, natural AI voiceovers, and the ability to detect and dub multiple speakers within a video. The key differences are the number of supported languages and the option in HeyGen to upload videos directly from YouTube.
Where they diverge most is in AI Video Translation workflows. AI Studios excels with streamlined options like batch translation and integrated editing, making it ideal for teams producing multilingual videos regularly. HeyGen provides broader language coverage, YouTube video support, and suits creators who value straightforward dubbing and don’t mind a more hands-on translation approach.
Ultimately, both platforms help bring your content to global audiences—the right choice depends on whether you prioritize workflow efficiency, advanced translation features, or language flexibility and web-based video support.
