Cap opened the infrastructure behind its own recorder to everyone as [Cap Infra](<https://cap.so/blog/introducing-cap-infra>), a video hosting and speech-to-text API.

Upload a video and you get adaptive HLS in up to five renditions from 360p to 4K, never above the source, plus one MP4, a poster image, a hosted player page and an iframe embed. To start, you [create an app in the dashboard](<https://cap.so/docs/api/get-started>), copy its secret key and add credit. Your server creates an upload and gets a short-lived token, and the browser sends the file in parts straight to storage. A video counts as ready as soon as its first output can play, and the rest finish in the background.

Speech to text also works by itself. Send a public URL or upload audio or video, and you get text back with word and segment timings. Uploaded videos aren't transcribed automatically. There's a hosted MCP server too, and a setup prompt you can paste into Claude Code, Codex or Cursor.

[Pricing](<https://cap.so/infra>) is prepaid credit per app, with no seats or plans. Uploading, encoding and the player are free. Storage costs $0.85 per 1,000 minutes a month up to 1080p, $1.45 at 1440p and $2.80 at 4K. Delivery is $0.95 per 1,000 delivered minutes, billed from November 14. Speech to text is $0.10 per audio hour, and Cap Pro includes $5 of credit a month. Uploads are capped at 36 GB.

Cap says an hour of 4K is playable in under 5 seconds after the upload finishes and fully processed in about 2 minutes, and that an hour of audio is transcribed in under 24 seconds. Those figures come from its own tests. The API, media server and player are open source.
