A single copy of Isadora running on one computer can output to multiple video projectors/beamers, a feature limited only by the power of your hardware. In addition, Isadora’s built-in tools allow you to create large-scale seamless images composed of multiple overlapping projections blended together into one.

Isadora 3 allows complex projector configurations to be set up easily using the Stage Setup editor, an approachable yet powerful tool for managing your video outputs, which we call Stages. For individual projector outputs, the Stage Setup editor allows you to quickly manage routing, key stoning, and preview options. It also offers easy integration with hardware like the Matrox TripleHead2Go, Datapath Fx4, or an MST hub so that you can access a larger number of projectors from a single computer.

The Stage Setup offers a video blending wizard which will quickly step you through the setup for multiple projector image blending. After using this wizard, you only need to adjust the output key stoning and edge blend curves to achieve a perfect, seamless image.
The Stage Setup editor also offers direct outputs via Syphon & Spout, NDI, and Blackmagic Design hardware for each stage. With a single click, you can activate these powerful video outputs, allowing you to send Isadora’s video output to other applications or devices.

Finally, the Stage Setup editor also offers a new “Virtual Stage” display type. Using a virtual stage, you can create video loopbacks that extend the video processing capabilities of Isadora even further.
