Why CaptionHub is the Smart Choice for Former cielo24 Customers
What happened to cielo24?
When cielo24 ceased operations on 30 September 2025, following its acquisition by Rev, many organisations were left without an accessibility partner overnight - facing compliance exposure, disrupted workflows, and the loss of years of institutional knowledge.
The good news: you now have the opportunity to rebuild on a more modern, scalable foundation designed for long-term success.
In this article, we will explore the differences of Rev and CaptionHub and highlight the advantages of switching to our all-inclusive platform as the best option for your needs.
Rev vs CaptionHub: A Direct Comparison
CaptionHub is the enterprise-grade accessibility and localisation platform trusted by global brands to deliver precise, compliant, multilingual media at scale.
Let's examine how Rev and CaptionHub compare across the capabilities that matter most to former cielo24 customers.
Captioning Capabilities
Rev's approach: Rev offers AI-powered automated captioning with human review options. Their transcription platform handles basic English captioning needs effectively, with a familiar interface that's accessible for simple projects. However, their primarily AI-first model means accuracy can vary, particularly with technical terminology, multiple speakers, or industry-specific vocabulary.
CaptionHub's approach: CaptionHub’s hybrid approach combines leading ASR technology with flexible human verification options, enabling you to achieve the accuracy of human captioning alongside the speed and scalability of automation. Our cloud-based platform gives your team granular editing control - adjust timing frame-by-frame, manage speaker labels, apply custom formatting, and maintain brand-specific style guidelines. The collaborative editing environment allows team members to review, refine, and approve captions before publication, ensuring every file meets your exact quality standards.
Why it matters: When caption accuracy affects compliance, accessibility commitments, and brand reputation, CaptionHub provides the control and precision you can't compromise on.
Language Coverage and Translation
Rev's capabilities: Rev focuses primarily on English transcription and basic captioning. Their language support for translation and multilingual subtitling is limited, making them suitable for predominantly English-language content but insufficient for organisations distributing content globally.
CaptionHub's capabilities: CaptionHub is a complete localisation platform supporting 200+ languages. The platform handles end-to-end multilingual workflows: transcription, translation by native linguists, subtitle timing optimised for target language reading speeds, cultural adaptation, and quality assurance - all coordinated through a single interface.
Unlike vendor-locked systems, CaptionHub’s open ecosystem lets you maintain relationships with your existing translation partners - while managing everything from one central platform.
Key capabilities:
- Vendor-agnostic LSP connectivity
- Centralised global project control
Why it matters: For organisations operating internationally, comprehensive language support isn't just a feature - it's the foundation of your global content strategy. CaptionHub delivers what Rev simply cannot.
Live Captioning Services
Rev's offering: Rev does not provide professional live captioning services with trained human captioners. Their automated solutions may handle basic streaming needs but cannot deliver the broadcast-quality accuracy required for corporate events, educational webinars, or compliance-critical live content.
CaptionHubs Offering: Timbra (formerly CaptionHub Live) delivers professional, broadcast-quality live captioning in real-time. Built on a robust platform, Timbra handles technical terminology, fast-paced dialogue, multiple speakers, and industry-specific vocabulary with precision. Whether you're broadcasting quarterly earnings calls, streaming educational lectures, delivering keynotes to global audiences, managing press interviews at major live events, or running compliance training webinars, Timbra ensures accuracy when your reputation and regulatory requirements are on the line.
Why it matters: Automated solutions simply cannot match human captioners for accuracy in complex live scenarios. When compliance and reputation are on the line, professional live captioning infrastructure isn't optional - it's essential.

Audio Description
Rev's capability: Rev does not offer audio description services. If you serve blind or low-vision audiences, this gap creates immediate WCAG compliance issues.
CaptionHub's capability: CaptionHub supports user-created audio description services through our caption editor, detection of a range of non-speech elements through our partner Speechmatics, and flexible workflows for users or LSPs to create and insert their own audio description text cues. We are fit for a variety of use cases from public sector communications to broadcast media. Whether you're managing a university's lecture library, producing public service announcements, or distributing entertainment content, our flexible workflows accommodate your specific audio description requirements.
Why it matters: Audio description isn't optional for many organisations—it's a legal requirement and a commitment to inclusive content. CaptionHub ensures you can meet these obligations without engaging separate vendors or managing disconnected workflows.
Platform Integrations
What cielo24 customers relied on: Many cielo24 customers depended heavily on the accessibility plugin to help make content user-friendly and more accessible. Rev's integration ecosystem may not match the breadth of platform connectivity that cielo24 customers are used to.
CaptionHub Connect: CaptionHub Connect integrates seamlessly with major OVP platforms—Amazon S3, Brightcove, Kaltura, Qumu and many more. Our flexible APIs ensure your accessibility and localisation workflows integrate smoothly across your technology stack. Captions, transcripts, translations, and audio description tracks sync automatically with your content library, eliminating manual file management and reducing version control errors.
Why it matters: Integration isn't just about technical compatibility—it's about ensuring your accessibility workflow fits seamlessly into your existing systems without rebuilding processes or forcing platform compromises.
Editing Control and Workflow Management
Rev's platform: Rev provides basic editing tools suitable for straightforward captioning tasks. However, organisations requiring sophisticated workflow management, collaborative review processes, or precise timing control may find the platform limiting.
CaptionHub's cloud workspace: CaptionHub is built as a collaborative cloud platform where teams manage complex accessibility and localisation projects. The platform provides frame-accurate timing controls for precise caption synchronisation, collaborative editing allowing multiple reviewers to work on the same project, custom glossaries ensuring terminology consistency, and workflow automation for repetitive tasks.
The project management pages gives you and your team full visibility into progress, approvals, and delivery timelines. Version control and rollback capabilities protect your work, whilst custom dictionaries and termbase rules apply automatically to maintain brand consistency and language accuracy across all projects.
Why it matters: For organisations producing high volumes of multilingual content, these aren't luxury features - they're essential infrastructure for maintaining quality and efficiency at scale.
Turnaround Times and Service Level Agreements
Rev's commitments: Rev provides estimated turnaround times ranging from 24 hours to 6 days. These are estimates, not guarantees - there are no Service Level Agreements backing delivery commitments.
CaptionHub's commitments: CaptionHub offers guaranteed turnaround times backed by embedded Service Level Agreements designed to ensure everything runs smoothly, both within the platform and across your production workflows for VOD and live events. Our SLA tiers include Base, Bronze, Silver and Gold. You receive clear delivery commitments you can build content calendars and compliance schedules around, with accountability when deadlines matter.
Why it matters: When you're managing tight production schedules or facing regulatory compliance deadlines, the difference between estimated and guaranteed delivery times is the difference between confidence and risk.
Data Privacy and Security
Rev's policies: Rev maintains a license to use customer data indefinitely and lists OpenAI as a subprocessor. For organisations handling sensitive content, proprietary information, or operating under GDPR, CCPA, or industry-specific data protection regulations, these practices warrant careful consideration.
CaptionHub's policies: CaptionHub is fully GDPR-compliant and committed to data sovereignty. Your content remains yours - never shared, sold, or used for AI model training.
Why it matters: For educational institutions handling student data, healthcare organisations managing patient information, financial services firms protecting proprietary content, or any organisation operating under strict data governance requirements, CaptionHub provides the privacy commitments you need.
Support and Customer Service
Rev's support: Rev offers email support and an article-based knowledge base. For complex technical issues, integration questions, or urgent project needs, this support model may not provide the responsiveness required.
CaptionHub's support: CaptionHub provides phone and Zendesk-powered support through our platform from accessibility and localisation specialists who understand the technical nuances of your workflows. We are committed to doing everything we can to address challenges in a timely manner within the agreed SLA’s, ensuring your projects stay on track and your team has the guidance needed to leverage the platform effectively.
Why it matters: When technical challenges or urgent deadlines arise, responsive expert support is the difference between smooth operations and costly delays.
End-to-End Media Localisation Infrastructure
Beyond the core comparison areas, CaptionHub delivers additional capabilities that enhance your accessibility and localisation infrastructure:
- Dubbing and voiceover services: CaptionHub manages professional dubbing and AI-powered voice-over projects for international content distribution. Our platform utilises Amazon Polly and Eleven Labs for high-quality synthetic voices, whilst also coordinating with human voice talent networks across languages for authentic, culturally adapted versions of your content.
- Scalable global delivery: Whether producing content in three languages or thirty, CaptionHub's platform scales with your requirements. Manage all language versions from a centralised dashboard whilst maintaining consistent quality standards.
- Complete workflow visibility: Track every project from upload through final delivery. Monitor translation progress, review caption files, manage approvals, and coordinate with LSPs and editors - all from one cloud-based platform.
The Strategic Choice
You're rebuilding your accessibility and localisation infrastructure regardless - the only question is which platform you choose to build on.
Rev is suitable for: Basic English transcription needs and simple, low-volume captioning projects.
CaptionHub is essential for organisations requiring:
- Professional live captioning via Timbra for broadcast-quality events
- Professional captioning with guaranteed 99%+ accuracy
- Comprehensive language support across 200+ languages
- Robust platform integrations via CaptionHub Connect
- Advanced editing control and collaborative workflows
