Challenge

A Fortune 500 company needed to scale their corporate training program across 50,000+ employees but faced significant challenges with traditional video production. Creating high-quality training content was expensive, time-consuming, and required extensive coordination between subject matter experts, video production teams, and learning designers.

Key challenges included:

  • High production costs ($10,000+ per training video)
  • Long lead times (4-6 weeks per video)
  • Difficulty updating content for rapidly changing topics
  • Language localization requirements for global workforce
  • Inconsistent quality across different production teams
  • Limited ability to personalize content for specific roles

Solution

We developed an innovative text-to-video generation platform that combines the narrative capabilities of open-source LLaMA with the visual generation power of Stable Video Diffusion, creating a comprehensive solution for automated training video production.
