ABOUT THE CLIENT
Chronicle Stream is a global video journalism platform. The organization manages an extensive digital library providing global access to thousands of archival and contemporary news videos. The client serves a global audience, requiring an infrastructure that performs consistently across diverse geographic locations and varying network speeds.
OVERVIEW
The project involved a complete overhaul of their aging infrastructure to support high-performance streaming and content management. The initiative focused on transitioning from a slow, bottlenecked system to a modern ecosystem capable of serving a global audience while providing robust tools for contributors and editors.

BUSINESS
REQUIREMENT
Chronicle Stream required a complete infrastructure modernization to overcome technical bottlenecks in content discovery and editorial workflows.
The primary objective was to transform a legacy video platform into a high-speed, scalable ecosystem capable of supporting global streaming, streamlined contributor management, and new monetization opportunities.
Key Requirements
The client sought to resolve critical operational inefficiencies that hindered growth:
1. Improved Discovery: Replacement of a slow search system plagued by heavy database joins.
2. Operational Speed: Drastic reduction in video upload and publishing lead times to improve editorial productivity.
3. Technical Modernization: Implementation of adaptive streaming for global users on various network speeds and a sophisticated thumbnail scrubbing system.
4. Monetization & Scalability: Integration of affiliate systems for revenue and a structured contributor management workflow with role-based access.
5. Content Utility: Support for bulk downloads and metadata-preserving video replacements.
SOLUTION
The GeekyAnts team implemented a high-performance platform centered on performance optimization, utilizing materialized views to achieve 10–20x faster search results and a re-engineered background pipeline that slashed video publish times to just 1–2 seconds.
To ensure a premium viewing experience, the solution integrated Bunny.net with adaptive HLS streaming for smooth global playback, complemented by enhanced UX features like an "Instagram-style" thumbnail scrubbing interface and an asynchronous, email-based ZIP delivery system for bulk downloads. The ecosystem was further strengthened by a comprehensive backend CMS that manages role-based content approvals and contributor onboarding, while an integrated affiliate tracking and commission system provides a scalable foundation for monetization.
Key Milestone:
The project launched with a foundational phase to establish core architecture and video upload structures, followed by the deployment of the materialized search system and adaptive HLS streaming. Development then expanded to include high-utility features such as dynamic thumbnail scrubbing, bulk download packaging, and frame capture.
To finalize the ecosystem, the team implemented an admin panel for contributor workflows and role-based permissions, integrated affiliate monetization tools, and conducted rigorous quality assurance focusing on streaming benchmarks and load testing.
CHALLENGES
IN EXECUTION
& SOLUTIONS
The project overcame significant technical hurdles by replacing slow database joins with materialized views, resulting in a 10-20x boost in search performance. To eliminate editorial delays, the team redesigned the upload pipeline for automatic background processing, slashing publish times from 40 seconds to just 1-2 seconds.
Technical complexity was further addressed by building a custom extraction pipeline to enable smooth thumbnail scrubbing for HLS formats and implementing an asynchronous packaging system to prevent browser timeouts during bulk ZIP downloads. Finally, the integration of adaptive HLS streaming ensured high-quality playback by dynamically adjusting to real-time bandwidth fluctuations.

OUR APPROACH
The platform was built using a high-performance web architecture featuring React for the frontend, Node.js for the backend, and PostgreSQL with Materialized Views for the data layer.
- Search Optimization: Implemented Materialized Views to pre-compute complex joins, ensuring that queries across thousands of videos return results 10-20x faster than traditional database queries.
- Advanced Media Pipeline: Integrated Bunny.net and HLS to create an adaptive bitrate streaming pipeline, ensuring high-quality playback regardless of global user bandwidth.
- Asynchronous Processing: Developed a background worker system to handle heavy tasks like video metadata extraction and bulk ZIP packaging, preventing browser timeouts and ensuring 100% delivery success.
- Admin & Contributor Workflows: Designed a robust RBAC (Role-Based Access Control) system within the CMS to allow secure, global collaboration between journalists and editors.
Design
The team began with requirement analysis and wireframes to establish information architecture, focusing on media-heavy interfaces. High-fidelity UI designs, featuring Instagram-like thumbnail scrubbing, were refined through weekly feedback loops.
Development Mobile & Web Frontend
Built with React, the frontend prioritized "scannability" and performance. The team used lazy loading and asset optimization to ensure that high-resolution video previews didn't compromise page load speeds.
Development – Backend
Using Node.js and PostgreSQL, the backend was architected for high throughput. Key innovations included Materialized Views for search speed and an asynchronous worker system for video ingestion and bulk ZIP packaging.
Admin Panel
A parallel development track created a robust internal ecosystem. This featured role-based access control (RBAC), metadata-preserving video replacement tools, and structured contributor onboarding workflows.
Global Delivery Strategy (CDN)
- Integrated Bunny.net for its global CDN capabilities to provide low-latency video delivery worldwide.
- Utilized Adaptive HLS Streaming to ensure a smooth, buffer-free playback experience by dynamically adjusting to user bandwidth.
- Implemented Reliable Caching strategies to ensure high-speed access to the extensive archive of thousands of journalism videos.
Strategic Integration
The team executed multiple integration cycles to weave together disparate systems—streaming, analytics, and affiliate tracking—into a cohesive unit. This ensured that monetization and reporting were baked into the core user journey rather than being "add-ons."
Testing & QA Process
- Conducted comprehensive Functional Testing across all user journeys, including upload, search, and admin workflows.
- Performed Streaming Quality Tests to validate adaptive playback across various network speeds and bandwidth conditions.
- Executed Search Speed Benchmarks to verify and optimize the target 10–20x performance improvement.
- Ran Load Testing on the bulk download system to ensure stability under high concurrent usage.
- Performed Regression and Cross-Browser Testing to ensure feature stability across all major platforms and devices.
PROJECT
RESULTS
The modernization of the platform delivered a high-performance ecosystem that transformed both the user and editorial experience. The technical optimizations achieved a 10–20x increase in search speed and reduced video publish times from 30–40 seconds to 1–2 seconds. User engagement was further enhanced through adaptive HLS streaming for smooth global playback and the implementation of advanced features like thumbnail scrubbing and multi-video downloads.
Beyond performance, the solution established a scalable business model by integrating an affiliate monetization system and a structured contributor management workflow, ultimately enabling seamless global access to thousands of news videos with significantly improved platform usage.
