The solution leverages Google Cloud’s Vertex AI to significantly enhance captioning efficiency, reducing both production time and expenses.

Warner Bros. Discovery and Google Cloud have announced the launch of an advanced AI-driven captioning solution, known internally as “caption AI,” in the United States, leveraging Google Cloud’s Vertex AI platform. This innovative technology is initially being implemented for unscripted programming, revolutionizing the captioning process for Warner Bros. Discovery by significantly cutting down production time and costs while improving the quality of captions for domestic audiences.

Historically, captioning has been a resource-intensive and lengthy task. To ensure high accuracy levels, Warner Bros. Discovery’s captioning solution employs a workflow that integrates Google Cloud’s Vertex AI platform for optimized captioning, along with human oversight for quality control. This data-centric strategy allows Warner Bros. Discovery to continually enhance and train the caption AI workflow, minimizing errors and aiming to provide consistently accurate captions.

Notable metrics include:

  • Time Savings: The caption AI workflow reduces caption file creation time up to 80% compared to manual captioning.
  • Cost Efficiency: The caption AI workflow cuts captioning costs up to 50%, enabling Warner Bros. Discovery to allocate resources more effectively.

"Providing viewers with high-quality captions is incredibly important to Warner Bros. Discovery," said Avi Saxena, CTO, Direct to Consumer, Warner Bros. Discovery. "Working with Google Cloud to utilize Vertex AI within Warner Bros. Discovery’s caption AI workflow has not only helped to accelerate our captioning process, but also has improved our efficiency and speed, while reducing costs.”

“AI has the potential to transform a variety of processes across the media and entertainment industry that deliver real business impact,” said Thomas Kurian, CEO, Google Cloud.“With its captioning solution, Warner Bros. Discovery is seeing an incredible example of how AI agents can save organizations time and money.”
