Dalet Flex LTS 25.12 marks a turning point in how modern media workflows are designed, deployed, and experienced. This latest Long-Term Support (LTS) release builds on Dalet Flex’s proven foundation while introducing a new generation of capabilities focused on intelligence, usability, and long-term scalability. From semantic search to workflow acceleration and AI-readiness, Dalet Flex is evolving to meet the demands of increasingly complex, multi-team media environments.

Just as importantly, this release lays the groundwork for Dalet’s next chapter, with native alignment to Dalet AI Services and the upcoming agentic intelligence layer, Dalia.

Let’s take a look at the top 7 new Dalet Flex LTS 25.12 innovations:

1. Dalet FlexXTEND: Offline Mode & Streaming Mode

Dalet FlexXTEND, the panel for Adobe Premiere Pro users, receives its most significant update to date.

Offline Mode: Editorial Freedom Without Connectivity

Editors can now continue working even when internet access disappears.

• Dalet FlexXTEND automatically caches media locally
• Editors can switch to offline mode instantly
• No work is lost during connectivity disruptions
• Ideal for travel, remote production, field editing, or low-bandwidth environments

This is a crucial enhancement for global workflows and hybrid teams.

Enhanced Streaming Mode

Dalet FlexXTEND can now stream proxy or high-res content directly into Premiere using MPEG-DASH, meaning:

• No downloads required
• Faster startup time for projects
• Lower local storage requirements
• Seamless collaboration across distributed teams

Additional FlexXTEND Enhancements

The release also includes:

• MOGRT support for Premiere motion graphics workflows
• Automatic selection of the best available Adobe Media Encoder (local or remote)
• Version control improvements (save as a new version or overwrite directly from FlexXTEND) 

Collectively, these features significantly improve editorial efficiency and collaboration for creative teams.

2. Semantic Search: Smarter Discovery and Metadata Workflows

One of the most impactful enhancements in Dalet Flex 25.12 is the general availability of Semantic Search, a transformative capability for media discovery.

How Semantic Search Works

Semantic Search is an AI-powered information retrieval technique that improves search accuracy by understanding the context, intent, and relationship behind a user’s query, rather than just matching keywords.

This means users can:

• Search using natural language
• Find content that lacks metadata or has inconsistent tagging
• Retrieve visuals, images, and documents based on contextual meaning
• Search across multiple languages

Example: Typing “dog playing on the beach” returns relevant shots, even if those specific words appear nowhere in the metadata.

Integrated Seamlessly in the UI

Semantic Search is activated directly in the Dalet Flex search bar, and queries can be mixed with traditional filters for powerful hybrid searches. 

This addition turns Dalet Flex into a far more intuitive system, lowering the barrier for new users and enabling teams to extract value from archives without time-intensive manual indexing.

It’s a massive time saver and efficiency boost for media workflows.

3. A Modernized and Intuitive User Interface

Dalet Flex 25.12 introduces major UI/UX refinements to improve simplicity, clarity, and productivity.

Key Improvements Include:

• Larger and more immersive tile browsing with higher zoom levels
• Compact views for quickly scanning large asset collections
• Cleaner navigation with a left-panel dedicated to structure (taxonomy, workspaces, etc.)
• A center panel focused solely on search results
• A right-hand panel optimized for preview and actions
• Wizard-driven customization options
• Human-friendly iconography for more intuitive use

These changes reflect the ongoing UI/UX modernization. Expect to see a newly redesigned homepage and future timeline-based metadata views in upcoming Dalet Flex LTS releases.

4. Big Backend Improvements: IMF Support & High-Performance Hot Folders

The release also brings efficiency and scalability improvements to backend operations.

Enhanced IMF Processing

Working with complex IMF packages is now smoother, more reliable, and optimized for large studio workflows.

Next-Generation Hot Folders

Hot folder ingestion has been re-architected to run natively in AWS, delivering:

• Faster reaction time
• More folders in parallel
• Improved performance under heavy ingest loads
• Better responsiveness in live workflows

These backend advancements make Dalet Flex even more robust for enterprise-scale deployments.

5. Ingest Portal: Now Available

Previously in beta, the Dalet Flex Ingest Portal is now officially available.

This centralized interface allows operators to:

• Control multi-source ingest
• Automate asset creation
• Manage Brio or InStream resources
• Configure ingest pipelines from a unified UI

Upcoming updates in 2026 will continue to improve functionality and user experience with FIFO recording, more granular permissions and support for 3rd party video servers.

6. Dalet AI Services: Built-In AI for Transcription & Metadata Enrichment

AI is a central theme for Dalet, and Dalet Flex 25.12 includes the first wave of native AI capabilities through Dalet AI Services:

• Built-in transcription
• Multi-language support
• Automatic metadata enrichment
• No third-party integration required
• Support for cloud and air-gapped on-prem environments

This foundation will expand with additional AI models and capabilities in future releases—paving the way for more advanced enrichment, analysis, automation, and contextual intelligence.

7. Dalia: Dalet Flex’s AI Future Becomes Reality

A major milestone in our roadmap is the upcoming release of Dalia, Dalet’s new agentic AI interface designed to orchestrate and simplify even the most complex media workflows.

And here’s the big news: this latest version of Dalet Flex (25.12) is the first release built natively to support Dalia, meaning customers who upgrade now will be ready to take full advantage of this breakthrough as soon as Dalia becomes publicly available later this spring.

What Is Dalia?

Dalia provides:

• A natural language interface to change the way you drive your media operations
• Multi-agent architecture that executes tasks behind the scenes working as your new media crew
• Even more efficiency and automation on top of Dalet Flex and other Dalet products

Whether you are an existing Dalet Flex customer or looking to become one, now is the ideal moment to build a future‑proof operational foundation designed for the age of agentic AI.. Dalia will be available in Q2, 2026, with the first customer POC taking place now. Stay tuned for more information on this exciting release!
