Warner Bros. Discovery (WBD) has deployed a new AI-powered captioning solution in the US that utilises Google Cloud’s Vertex AI platform.
WBD said the technology is significantly reducing production time and the cost of creating and delivering captions, and is enhancing the quality of its captioning for domestic viewers.

In particular, WBD said the caption AI workflow reduces caption file creation time by up to 80% compared to manual captioning. Captioning costs are down up to 50%.
WBD is initially applying the captioning solution to unscripted programming.
WBD’s captioning solution incorporates a workflow that uses Google Cloud’s Vertex AI platform to optimise captioning coupled with human oversight for quality assurance.
This allows WBD to refine and train the caption AI workflow, reducing errors and helping to generate more precise captions in the future.
“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 utilise 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 organisations time and money.”
