Spreadsheets Aren't Scaling With You
Language service providers and accessibility teams are drowning in disconnected tools — spreadsheets for tracking, separate apps for transcription, another for translation, and manual file-shuffling for delivery. Every handoff is a risk. Every gap costs time and money.
Closed Caption Unity is the operations platform for captioning, subtitling, translation, and audio description. It manages media assets, runs production workflows, opens work in Closed Caption Creator, publishes house formats through Closed Caption Converter, and delivers finished files to streaming and MAM systems. Use the full stack — orders, projects, and tasks — or only the pieces you need.
Built for How Caption Teams Actually Work
Not another generic task tracker. Unity manages your media, runs production, opens work in the editor, publishes house formats, and delivers finished files — from one platform.
Purpose-built caption production
Assets, projects, tasks, and deliveries are first-class objects — not rows in a spreadsheet. Unity understands media files, caption formats, QC rules, and where finished work needs to go.
Professional editor, in the workflow
Tasks open in Closed Caption Creator with proxy video, waveform, transcripts, and shot-change markers already loaded. Save, publish, and complete write back into the project — no file-shuffling between tools.
Media library, not a shared drive
Browse a virtual folder tree, search, star favorites, and inspect proxy playback with captions. Originals, proxies, transcripts, subtitles, attachments, and audio description live on the asset with full history.
Orders for client work
Group projects under a customer when you are producing for clients. Track status from ingest through delivery, and report on work by account — without turning Unity into an invoicing tool.
Freelancer-ready task queues
Captioners and reviewers see only the work assigned to them. Project owners can still launch any task. Guest links let external editors complete work without a full workspace login.
Automated ingest pipeline
Upload a file, drop in a URL, or pull from Google Drive. Unity can generate proxies, thumbnails, waveforms, shot changes, and technical metadata, then start transcription automatically.
AI that stays in the loop
Automatic transcription (Speechmatics or Deepgram) and machine translation (Lara) handle the repetitive work. Humans still QC, edit, and approve before anything is delivered.
House-format publishing
Publish from the editor into approved formats — SCC, SRT, WebVTT, TTML/IMSC, MCC, EBU-STL, and 45+ caption formats via Closed Caption Converter. Admins lock which formats editors are allowed to produce.
Caption quality templates
Project templates enforce reading speed, line length, duration, overlap, and frame-gap rules in the editor — so every job starts with your house style, not a blank file.
Deliver to the platforms you already use
One-click delivery to YouTube, Vimeo, Mux, Brightcove, Frame.io, Bunny Stream, Cloudflare Stream, Google Drive, Iconik, Telestream Vantage Cloud, and S3 / R2 / GCS.
Audio description production
Editors can publish timed audio description as a voice-over or mixdown (with loudness targets), then deliver AD alongside captions where the destination supports extra audio.
Your data, your infrastructure
Run Unity in the cloud or on-premise. Bring your own storage and keys. Media never has to live in a vendor silo you cannot leave.
Your Media, Organized and Intelligent
Custom metadata schemas, web-based UI, custom workflows, caption conversion, and proxy playback. Automatic technical metadata extraction and advanced search — built for teams managing growing volumes of media files.

Files trigger automatic transcription, translation, or transcoding. Define custom "Trigger → Action" logic to eliminate manual file handling — so your team can stop managing spreadsheets and start delivering faster.
