Dubbing and Voice-Over
Bring every story to a new audience. Manage your complete dubbing and voice-over workflow in Stellar, from script and casting to recording and delivery. Work with professional or synthetic voices, record remotely, and adapt performances with respeeching, voice cloning and voice morphing.
Compliance and timed text
Deliver with confidence. Combine automated and human review to identify compliance issues and prepare content for different audiences and markets. Use compliance tagging and QC workflows to flag, review and resolve regulatory, cultural or audience-specific issues.
Automate
Let Stellar handle the repetitive work. Build workflows that connect people, AI services, conversions, QC and delivery. Giving your team more time for the work that requires human expertise.
Manage
See the bigger picture. Manage projects, tasks, users, media, resources and progress from one central environment, with visibility across your entire localization operation.

'We have worked with Yella Umbrella for several years on analysing and processing our extensive subtitle archive. As we move to a new streamlined system, we have integrated The Stellar Suite to support our growing content needs. We use Stellar to conform multiple languages in a single session, create subtitles, perform automated subtitle conversions, and retime existing subtitle files. These capabilities have allowed us to maintain high quality standards while improving efficiency. This balance between automation and editorial control is exactly what we need'
Vice President of Technical Operations, Global Technology at BBC Studios
“We wouldn’t have been able to complete this intricate AD project without the shared task capabilities in Stellar. It simplified version control, enabled real-time QC, and allowed feedback without endless file sharing. It also keeps assets secure since only the project is shared, not the high-res media files.”
