Creating Multi-Language Learning Content at Scale

Client:

Beyönd

Industry:

Learning & Development / Serious Games

Region:

Europe

Use Case:

Localization of AI-generated video content

Content Type:

Long-form educational videos, character-driven narratives, game-based learning

Beyönd, founded by Laurent Rozenfeld, builds immersive educational video experiences designed to engage learners through realistic, character-driven storytelling.

Their content relied heavily on long-form scenes, but scaling it beyond a single language was difficult. Localizing large volumes of video risked losing natural delivery, character integrity, and overall credibility.

With LipDub AI, they were able to adapt existing content for multiple languages—preserving performance quality while scaling efficiently across French, Dutch, and English.

The Challenge

Before LipDub AI, Laurent’s workflow involved piecing together multiple tools for translation and lip sync, often resulting in clunky, unnatural outputs. With long-form scenes and multiple speakers, most solutions fell apart when applied to anything beyond 6–8 second clips.

Laurent’s vision required long-form, emotionally expressive video scenes that felt natural in multiple languages. In practice, that created several challenges:

  • Most existing AI tools couldn’t handle complex dialogue or character consistency beyond short clips
  • Lip sync and voice quality were either robotic, visibly fake, or unable to match longer narratives
  • Legacy approaches like reshoots or manual dubbing were too expensive, slow, or inconsistent for agile learning environments

As a solo creator building multi-character narratives, Laurent needed a way to localize at scale without compromising visual quality, credibility or resorting to costly, time-intensive workflows.

The Adoption

Laurent built a custom workflow integrating AI-generated characters with LipDub AI’s high-fidelity lip sync and translation tools. This included:

  • Uploading long-form AI-generated video scenes
  • Translating English audio into French and Dutch using both external tools and LipDub’s built-in translation workflows
  • Using LipDub AI to apply lip sync for each translated version, preserving facial emotion, timing, and character consistency
  • Training models per video for better accuracy, with selective frame deletion to improve output fidelity

Laurent favored LipDub’s proprietary training model for its natural articulation and ability to handle longer clips better than any other solution and appreciated the option to scale output speed without compromising on believability.

The Solution

LipDub AI was the first solution that could handle long-form, multi-character scenes without breaking realism. It addressed the core limitations of existing tools and gave Laurent a more reliable workflow for producing multilingual content that maintained visual credibility at scale.

Key improvements:

  • End-to-end localization of character-based, AI-generated scenes across 3 languages
  • Higher ROI per asset by adapting content vs. rebuilding it
  • Natural articulation in translated versions that matched the original’s emotion and nuance
  • Efficient long-form processing, with support for 7+ minute scenes in a single pass

Built-in editing and clean-up tools (e.g., training image filtering) that improved quality while simplifying workflow
