'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.”
