Automated Video Media Processing & Distribution Pipeline
Overview
An event-driven media automation pipeline designed to modernize the fansubbing workflow.
By automating the entire technical delivery pipeline — including encoding, muxing, verification, and release distribution — the system eliminates manual bottlenecks and significantly reduces operational workload, allowing localization teams to focus entirely on human-driven creative tasks such as translation and typesetting.
Key Highlights
- Automated torrent ingestion and release orchestration
- Parallel queue-based media processing
- Programmatic subtitle, font, chapter, and CRC32 handling
- Integrated Pixeldrain release distribution
- Real-time synchronization and Discord notifications
