Gaupol vs OOONA

Gaupol is free subtitle-editing software for creating and translating text-based subtitles, timing them to video, and correcting common errors. It supports multiple subtitle formats and lists SRT and VTT export. A built-in video player is available, with an option to launch an external player. Gaupol is Free Software under the GNU General Public License, with a free plan priced at free. Linux is the current availability listed by the maker, with Flatpak, source code, and packages for most popular distributions. Windows installers are no longer built; the latest Windows version is 1.3.1 and its built-in player is disabled. The integrated player uses GStreamer, and additional plugins are recommended for broader container and codec support. Optional source dependencies cover spell-checking and character-encoding detection. Gaupol includes aeidon, a separately installable Python package for subtitle-file manipulation. Documentation, discussions, and an issue tracker provide support channels.

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.
