The Operations Layer for Accessible Media

Closed Caption Unity is the missing operations layer for captioning and accessible media. Manage assets, run production, edit in Closed Caption Creator, publish house formats, and deliver to the platforms your clients already use — on your infrastructure, with your keys.

Production workspace

Everything your coordinators and operators need to see what is due, who is on it, and what ships next.

Dashboard

A live snapshot of open work, due orders, assigned tasks, recent assets, and active projects. Operators can rearrange widgets; org admins also see credits, storage, and team size.

Assets

The center of Unity. Each asset holds media, metadata, linked projects, jobs, and delivery history. Assets work even if you never create a project.

Projects

One asset, many jobs — for example English captions and French subtitles on the same source. Duplicate projects to reuse task structure and QC settings. Kanban view for task status.

Orders

Optional business layer: batch client work, track lifecycle (Open → In Progress → Review → Ready for Delivery → Closed), and deliver the whole order at once.

Customers

Client records (name, logo, contacts) so orders can be filtered and reported by account. Not an invoicing system.

Personal task list

A “what do I do next?” queue for captioners, translators, and QC. Assigned users can work a task even if they cannot see the parent project.

In-app notifications

Assignment and workflow alerts in the toolbar, so operators do not live in email.

Caption & accessibility editing

A professional editor built into the workflow — powered by Closed Caption Creator.

Embedded Closed Caption Creator

Full professional editor inside Unity: timing, positioning, speakers, QC, search/replace, and more. Keyboard shortcuts and editor preferences follow the user.

Auto-loaded resources

Proxy, waveform, first subtitle file, and transcript load when a task opens. Load Resource can add shot-change markers and other asset files mid-session.

Transcript sync

Check Sync / Resync align caption events to a transcript already on the asset.

Publish without leaving the editor

Choose an export profile; Unity converts and attaches the file to the asset. Publishing does not close the task, so editors can export as they go.

Caption QC in real time

Max CPS/WPM, min/max duration, max lines, max characters per line, overlap protection, and frame gaps — enforced while editing.

Audio description export

Kokoro TTS stitches cues into FLAC, MP3, or WAV. Voice-over or ducked mixdown, with optional EBU R 128 / ATSC A/85 / LUFS loudness.

Proxy review player

Browser playback with caption tracks so producers can review without downloading masters. Optional visual watermark (email, IP, date/time, custom text) on proxy players.

Ingest, processing & AI

Media arrives ready to work — proxies, metadata, and a first-pass transcript, with humans in the loop.

Direct-to-storage upload

Files go straight to your object storage (S3 multipart or GCS resumable). Unity does not proxy the bytes through the app.

Remote ingest

Pull from a public HTTPS URL or Google Drive.

Typed media files

Original, proxy, audio, thumbnail, transcript, subtitle, shot changes, waveform, attachments, and audio description — each can live in its own storage location.

Proxy & review media

Automatic 720p proxy, thumbnail, spritesheet, and waveform so editors are ready immediately.

Shot-change detection

Markers for the editor via FFmpeg or Google Video Intelligence.

Technical metadata

Duration, frame rate, drop-frame, resolution, and codec extracted on ingest.

Automatic transcription

Speechmatics (language auto-detect; SaaS default) or Deepgram. Timed transcript lands on the asset for editing and sync.

Automatic translation

Lara AI translates published subtitles into target languages and attaches the new files — with a human review step in the workflow.

Bring your own keys

Connect your own transcription, translation, transcode, TTS, storage, and platform credentials.

Formats & delivery

House formats in, finished files out — powered by Closed Caption Converter.

45+ caption formats

Closed Caption Converter handles SCC, SRT, WebVTT, TTML/DFXP/IMSC, MCC, EBU-STL, Cavena 890, iTunes Timed Text, and many more.

Export profiles (house formats)

Admins decide which formats editors may publish, plus conversion filters (reading speed, event gap, auto QC, 608/708, encoding).

Delivery profiles

Templates for “what files, which account, which platform.” Deliver from a project, an order, or the API.

Streaming platforms

YouTube, Vimeo, Mux, Brightcove, Bunny Stream, Cloudflare Stream — video plus captions (and extra audio / AD where the platform supports it).

Review & MAM

Frame.io (per-asset folder), Iconik, Telestream Vantage Cloud, Google Drive.

Object storage delivery

Copy required files to Amazon S3, Cloudflare R2, or Google Cloud Storage with prefix/filename control.

Teams, security & access

Give every captioner, reviewer, and freelancer exactly the access they need — and nothing more.

Organizations

Isolated tenants. Users belong to one organization.

Roles & workspace rights

Super admin, admin, user, and guest, plus per-workspace rights (assets, orders, projects, tasks, customers, upload, download, editor, and so on).

Teams & ACLs

Folder, profile, metadata, and order permissions by user, team, or everyone. Permissions are additive — the more-permissive grant wins.

Skill-based auto-assign

Attributes (for example “Spanish Translation”) on users and tasks automatically route work.

Guest task shares

Password-optional public links, optional expiry, email to Unity users or external addresses. Freelancers can complete a task without full product access.

Two-factor authentication

Authenticator apps (TOTP) and backup codes. Organizations can require 2FA for password users.

SAML 2.0 SSO

Enterprise / on-prem: Okta, Entra ID, or any SAML 2.0 IdP, with just-in-time provisioning.

Google sign-in

Available on the SaaS product.

Password policy

Per-organization length and complexity rules.

Encrypted credentials

Third-party API keys stored encrypted at rest.

Platform, automation & deployment

API-first and built to fit your infrastructure — in our cloud or yours.

Visual workflows

State machines with notify, create job, update metadata, and update delivery status. Ingest and delivery profiles attach to these machines. (On SaaS, platform workflows are seeded; on-prem admins can build their own.)

Custom actions

Right-click actions on assets and folders: open a URL, POST to an endpoint, or start a workflow (for example Automatic Translation).

REST API

The Workspace UI is a client of the same public API. Session or API key. Headless Unity is a supported model.

Webhooks

Subscribe to asset, project, order, task, ingest, folder, workflow, and delivery events. At-least-once delivery with idempotent event IDs.

MCP server

Connect Cursor or Claude to your Unity instance to search records, update tasks/orders, and trigger non-delivery workflows. Media stays on your instance.
