Ensure every asset meets regional standards and audience expectations with advanced compliance tagging and QC workflows. Whether you’re delivering content for global broadcast, streaming, education, or other entertainment, Stellar gives you the tools to flag and fix content that may violate regulatory, cultural, or audience-specific standards. Our combination of automated and manual review tools ensures every asset is suitable for its intended market.
Smarter compliance, safer content
From detection to delivery: End-to-End compliance for broadcast, VOD, and more
Ensure your content meets global standards and audience expectations. With Stellar’s advanced compliance tagging and QC tools, you can automatically detect sensitive material, support manual review, and generate detailed reports for any platform or region.
AI-driven detection of sensitive content
Stellar includes an automated tagging engine that scans media for:
- Profanity and offensive language
- Sexual references or nudity
- Violence and abuse
- Substance use
- Hate speech and slurs
Each flagged instance is logged with timecodes and confidence levels, so human reviewers can validate or override.
Tagging output options:
- Compliance metadata exports (JSON, XML, CSV)
- Auto-generated edit decision lists (EDLs)
- On-screen warning indicators in the interface
Manual review & tagging tools
Empower your QC teams
While AI covers the bulk of detection, trained QC professionals can:
- Confirm, modify, or dismiss automated tags
- Add context-specific tags based on client requirements
- Apply market-specific compliance labels (e.g. ESRB, PEGI, BBFC)
- Annotate content with notes for editors or legal reviewers
- Add Break markers for possible advert insertion points
Reviewer interface features:
- Side-by-side video playback and waveform view
- Timecode-linked comment threads
- Multi-language support for foreign-language review
Quality control in all areas that you can trust
Built-in QC checks for every stage
- Subtitle and caption QC: spelling, timing, readability
- Audio QC: missing clips, text edit after recording warnings
- Format and delivery validation: EBU, FCC, OTT specs
Automated & manual hybrid workflows:
- Flag issues automatically
- Assign for manual review with contextual instructions
- Track issue resolution across steps
Full compliance reporting

- Broadcasters
- VOD platforms

'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.”
