OOONA vs Subtitle Edit

OOONA provides management and production software for media localization, covering subtitling, voiceover, dubbing and captioning. OOONA Integrated combines a translation management system with production tools for end-to-end project management. It offers customizable project and client dashboards, automated and bulk assignments, live project and user metrics, and access controls for internal and external users. OOONA Tools can be selected individually or in packages and include Create + Translate, Translate, Review, Transcribe, Subtitle Converter, Burn & Encode, Multilingual QC, Compare and Audio Description. Create + Translate supports timed-text authoring, editing, translation and reformatting with precise positioning and frame-accurate timing. APIs handle subtitle and caption conversion, validation, configurable checks, and automated work-order intake and delivery updates. Integrated supports single sign-on through Auth0, Microsoft ADFS, Microsoft Azure, MiniOrange and Okta, plus APIs for third-party language and client-management systems. OOONA says it uses DRM-protected video, browser-based work without transferring video assets, multifactor authentication, watermarking and continuous penetration testing. A free trial lasts four weeks with limited subtitle export; Timed Text Lab offers free, account-free timed-text tools.
