The Challenge
Creating accessible videos manually is time-consuming and expensive. Organizations needed an automated platform capable of generating captions, transcripts, audio descriptions, and accessible video outputs while supporting large video files and reliable background processing.
The Solution
Accessify Video automates the complete remediation workflow. Users upload videos, AI analyzes the content, background workers process media, and the platform generates downloadable transcripts, captions, audio descriptions, and accessible videos with resumable processing.
Platform Features
Caption Generation
Creates synchronized SRT and VTT captions.
Background Processing
Processes long videos asynchronously with resumable checkpoints.
Stripe Payments
Secure online payment integration for accessibility services.
Download Center
Users can download all generated accessibility assets.
Architecture
The platform is built using React, Node.js, PostgreSQL, Firebase Authentication, FFmpeg, Gemini AI and background workers. Videos are processed asynchronously with resumable checkpoints to ensure reliability during long-running jobs.
Development Process
The application evolved from a synchronous processing workflow into a scalable background processing platform. Segment rendering, checkpoint recovery, polling, queue processing, and fault recovery were introduced to improve production reliability.
