Lightcast Launches AI-Powered Video Dubbing and Subtitle Generation to Help Content Owners Reach Global Audiences

New Media Cloud capabilities enable organizations to localize video libraries in hours instead of months while reducing costs by more than 90 percent.

CHARLOTTE, N.C., July 29, 2026. Lightcast, the leading provider of digital media and streaming technology solutions, today announced the launch of AI Subtitles and AI Dubbing within the Lightcast Media Cloud, enabling content owners to instantly localize video libraries into over 35 languages, with an additional 20 languages expected soon, through a simple, integrated workflow.

The new capabilities allow organizations to easily generate multilingual subtitles, dubbed audio tracks, and localized metadata directly within the Lightcast platform. This eliminates the need for traditional localization vendors, recording studios, and complex project management.

"Organizations have spent years building valuable content libraries, but much of that content remains inaccessible to audiences around the world because localization has historically been too expensive and time-consuming," said Andreas Kisslinger, Founder and CEO of Lightcast. "With AI Subtitles and Dubbing, we're removing those barriers and making global distribution as simple as clicking a button."

Traditional dubbing can take three to four weeks per season and cost approximately $10,000 for a single half-hour program. Lightcast's AI-powered workflow can generate localized versions in approximately 90 to 120 minutes at a fraction of the cost.

Beyond Subtitles: A Fully Localized Viewer Experience

Localization in the Lightcast Media Cloud goes further than translated text. Every video automatically receives localized titles, descriptions, and metadata alongside translated thumbnails, gallery images, and artwork, so international viewers see a version of the content built for them, not just a subtitled original.

Publishers Stay in Control

Every AI-generated asset, including subtitles, dubbed audio, thumbnails, and metadata, is clearly marked with an AI indicator and remains fully editable. Subtitles can be fine-tuned in a built-in visual editor, and any asset can be reviewed, replaced, or modified at any time.

"AI makes recommendations and accelerates content creation, but every element remains fully editable by human users," said Kisslinger. "You're never locked into AI-generated content; it simply helps save time. Organizations never give up control of their content."

Localization Built Into the Publishing Workflow

Once content is localized, it doesn't sit and wait to be distributed. Workflow presets in the Media Cloud automatically route each new localized version, through language-specific channels, to web, mobile, TV, connected car, gaming, smart speaker, and social destinations. Multi-platform publishing that once required manual, market-by-market coordination now happens automatically as part of the same workflow that creates the localized asset.

Know Which Markets Are Working

Because analytics are organized by channel, including language-specific channels, publishers can measure performance market by market: which countries are watching, which language channels drive the most engagement, and how content performs by device, region, and time period. Localization decisions can now be backed by data instead of guesswork.

Key capabilities include:

  • AI-powered dubbing in 35 languages, with 20 more expected to launch shortly
  • Automatic subtitle generation and translation, with a built-in visual editor for fine-tuning
  • Localized titles, descriptions, metadata, thumbnails, and artwork
  • Preservation of original speaker voice characteristics
  • Regional dialect support, including Latin American and Castilian Spanish, Brazilian and European Portuguese, and Mandarin and Cantonese Chinese
  • Full editorial control, with AI-generated assets clearly marked and reviewable, replaceable, or editable at any time
  • One-click, channel-based publishing that automatically distributes each localized version across web, mobile, TV, connected car, gaming, and social destinations
  • Built-in analytics to measure engagement and reach by language and region, so organizations can identify top-performing markets and languages

The technology is already being used by organizations localizing hundreds of videos for global audiences, demonstrating the scalability and operational simplicity of AI-powered localization.

"Localization is no longer a project. It becomes part of the publishing workflow," added Kisslinger. "Organizations can test new markets, serve multilingual audiences, and extend the value of existing content libraries without building an entirely new operational infrastructure. And with analytics broken out by language and region, they can see exactly which markets are worth doubling down on."
