Supertitle generator for opera ...caption any kind of scripted live performance.

Produce multiple translations simultaneously. Offer up to four separate simultaneous translations, or differing format presentations, by adding Display Windows.

Title text fades up and down at rates you determine during performance. No pre-programming of transitions is required.

Broadcast all four translations over your local area network to wireless devices using LiveTitles. Send live supertitles to any internet-connected device with LiveTitles Tx and LiveTitles Web Server.


For live presentation of titles/captions, TitleDriver was developed for opera and is useful for any form of scripted live event. TitleDriver is available for Mac OS computers only.

TitleDriver was originally developed to produce video for projectors and video walls. For video output, you will require a computer equipped with at least two video outputs, one for the operator's monitor, and one for a Display Window. Almost any MacBook model gives you that capacity right off the shelf.

Additional video outputs are required for each additional Display Window you wish to present. It is also possible to present two translations (Display windows) together in a single video output.

TitleDriver also broadcasts title text to network devices. The LiveTitles system for your local network, and LiveTitles Web Server, to reach your audience's mobile devices.

Title text is formatted using your preferences, and a variety of format commands can configure each title uniquely. Format commands provide many additional functions, such as the ability to layer text, add graphics or other useful functions.

You are not required to pre-program the speeds of transitions. All cues are taken live, but it is also possible to pre-program fade times for each title, if required.

LiveTitles Web Server

LiveTitles Web Server is our newest component, available to your company as a separate service to provide live TitleDriver text to web-enabled devices. For an ongoing monthly fee of $90, your company will maintain a dedicated server that delivers live performance captioning to your patrons. One server can handle over 250 simultaneous users, and our service provider is working on a robust multiple server solution that can accommodate any likely number of users.

You create a URL like "livetitles.yourcompany.com" that patrons use to connect to the server. Response time is fast: users in the Continental U.S. typically receive captions on their devices well under a second after the text appears live in the theater.

LiveTitles Web Server sends a single translation only. Additional LiveTitles Web Servers are required to provide additional simultaneous translations via the internet.

...we manage the server for a low monthly fee.

No long term commitment required. Subscribe month-to-month as needed for your venue.
