At Oxobox, we believe true innovation happens when industry challenges push us to rethink workflows.
Back in 2015, the Netflix engineering team gave us a unique challenge: remove their famous “Tutum” audio logo from thousands of assets, each synchronized with dozens of subtitle tracks in multiple languages. The issue wasn’t just technical—it required maintaining runtime consistency across every language version.
That project was a turning point for us. We realized that reviewing subtitles one by one was inefficient and unsustainable. Imagine opening 30 subtitle files separately, losing context each time, and starting over. Our breakthrough was to see all subtitle tracks at once in a vertical timeline, enhanced with heatmap-style anomaly detection.
That idea evolved into what is now the Oxobox Package Player:
A unified environment where video, audio, and subtitles can be reviewed together.
An interface that highlights anomalies visually, allowing Project Managers to spot issues—even in languages they don’t speak—through a color-coded system.
Real-time collaboration, much like Google Docs, with multiple users simultaneously reviewing and fixing content.
The strategic advantage is clear:
Teams gain a holistic view of the full package, not just isolated components.
Quality control (QC) is dramatically faster, with errors and inconsistencies flagged instantly.
Managers and specialists work more efficiently, reducing rework and ensuring reliability at global scale.
Today, the Oxobox Package Player is more than a tool for subtitle management—it has become a mission-critical collaboration system for streamers, broadcasters, and distributors who demand speed, accuracy, and scalability.
Watch the video now to see how a paradigm shift in review workflows can transform your entire media supply chain.
The Oxobox Package Player provides a unified, secure environment to review all components of an audiovisual asset with precision and efficiency. In this video, you’ll learn how the Package Player enables teams to:
- Play back video, audio, and subtitle tracks in multiple languages — all frame-accurately synchronized.
- Navigate easily with waveforms, subtitle alignment columns, and version comparison tools.
- Perform real-time QC analysis on subtitle files, with over 50 automated checks and color-coded anomaly visualization.
- Review and switch between multiple audio versions such as dubs, commentary, or audio description.
- Annotate content with time-coded, clickable comments, integrating external QC reports from Adobe Premiere, Baton, and more.
- Collaborate seamlessly across technical, editorial, and QC teams in one shared space.
Running in a secure, TPN+ compliant sandbox, the Package Player reduces turnaround times, minimizes errors, and streamlines the full review and approval workflow.
