What Closed Caption Creator does
Closed Caption Creator Inc. is a privately held Canadian software company headquartered in Cambridge, Ontario (originally founded in Brantford) that builds professional-grade caption and subtitle tooling for the broadcast, streaming, and post-production industries. Its flagship product, the Closed Caption Converter, accepts more than 30 caption and subtitle formats — including broadcast-delivery-specific deliverables for Netflix, iTunes, and DVD authoring — and translates them into a proprietary internal project format (CCPRJ) editable in a companion editor, then re-renders to the requested output format.
The product is delivered through three surfaces: a hosted web application for individual editors, a REST API for engineering integrations, and an on-premise CLI binary for air-gapped enterprise and government environments. Around this core converter the company has assembled an integration layer spanning nine third-party transcription providers (including Deepgram, AssemblyAI, Speechmatics, Rev AI, Google STT, Amazon Transcribe, Voicegain, ElevenLabs, and OpenAI Whisper), seven machine-translation providers (DeepL, ModernMT, Google Translate, Amazon Translate, Gemini, OpenAI, and Azure AI Translator), four cloud storage targets (AWS S3, Google Cloud Storage, Azure, Backblaze B2), and a native connector for the Iconik media asset management platform.
Revenue is generated through a $10/month or $100/year subscription for the web app, a $0.10/job usage tier for API and CLI customers, and presumably custom enterprise agreements for larger broadcasters and post-production vendors. Disclosed enterprise customers include Fox, NBC, Warner Bros. Discovery, PBS, Crunchyroll, PokerGO, Sky, YesTV, SDVI, Kanopy, and Overdrive, and the platform processes more than 100,000 files per month. The company operates with 1–10 employees, has not disclosed any external funding rounds, and has no published leadership team.

Closed Caption Converter is a professional caption and subtitle processing platform that converts, edits, and aligns caption files across 30+ industry-standard formats including broadcast standards (SCC, MCC, EBU-STL) and streaming formats (WebVTT, SRT, TTML). It is delivered as a browser-based web app for ad hoc conversion, a REST API for automated cloud pipelines with transcription and translation connectors, and a self-contained CLI binary for secure on-premise and air-gapped deployments. The platform automates timecode rippling, frame rate conversion, segmentation, QC validation, and delivery to cloud storage and MAM systems.
Product overview
Closed Caption Converter is a professional-grade caption processing platform offered across three deployment forms: (1) a zero-install web application for browser-based subtitle conversion with local processing, (2) a REST API for cloud-based automated workflows supporting transcription, translation, alignment, and cloud storage delivery, and (3) a CLI binary for secure on-premise and air-gapped environments. The platform converts between 30+ closed caption and subtitle formats including broadcast standards (SCC, MCC, EBU-STL) and streaming formats (SRT, WebVTT, TTML). The ecosystem includes Closed Caption Creator, a companion professional timed-text editor for manual captioning and editorial review, which integrates with the API to enable hybrid automated + human-review workflows. Third-party integrations provide access to speech-to-text transcription (Deepgram, Assembly AI, Speechmatics, Rev AI, OpenAI Whisper, etc.) and machine translation (DeepL, Google Translate, Amazon Translate, Gemini, OpenAI, Azure AI Translator).
