# Zero hardware. Real-time captions on YouTube. Maestro Console posts live CEA-608 closed captions straight to your YouTube ingestion URL — and the same keypress drives your surtitle projection and every language on your audience's phones. ## One keypress. Three destinations. No drift between them. Space fires the cue. The projection jumps to that line, the stream gets the caption, and every connected phone updates — from one action, off one script, in every language the script holds. ### Above the stage *OSC → Glypheo* Maestro drives your existing Glypheo projection over OSC. It does not send "next" and hope — it sends the absolute cue number, so the screen is pinned to the line you just fired. Undo re-sends the earlier number and the projection follows it back. Example: FR — “Gloire immortelle de nos aïeux” ### On the livestream *HTTP POST → YouTube* The cue is posted as a live CEA-608 caption to your YouTube ingestion URL — several streams at once if you run them. Nothing sits in the video path, so there is no capture card and no encoder to rack. A delay dial lines the captions up with the picture your viewers actually receive. Example: EN — “Immortal glory of our forefathers” ### In the audience's hands *SSE → audience phones* Anyone on the house network opens one page and picks their language. Every language in the script reaches the phones — not only the two the stream can show — so the surtitles carry languages the projection has no room for. No app, no download, and nothing leaves the building. Example: EN — “Immortal glory of our forefathers”; DE — “Unsterblicher Ruhm der Ahnen”; IT — “Gloria immortale dei nostri avi” ## How a performance runs Three phases, and the only one that happens during the show is the middle one. 1. **Load the script.** Excel, CSV, plain text, SRT or PowerPoint. In a spreadsheet one row is one cue and each column is a language, so the languages cannot drift apart — they are the same row. Pick the one or two that go out on the stream; every other column goes to the phones. 2. **Run the show.** Space fires the current cue to all three destinations at once. Undo does not just step back — it re-fires the previous line, so the wrong caption is overwritten rather than left up. Escape clears the stream and the phones for instrumental passages. 3. **Hand over the recording.** Recording writes an SRT subtitle file for each stream language, timed from what actually happened on the night, alongside a performance log of every cue, undo and blackout that you can export when the curtain is down. ## See it run against your own script. Send a scene and the languages you run, and you get it back as a working session rather than a slide deck. [Request a demo](https://maestroconsole.com/contact/)
