Theater Performances

  • Easily sequence a series of video clips to accompany your performers on stage using our new Drag and Drop workflow.
  • Instantly scale and reposition video images by adjusting a few parameters.
  • Isadora’s new IzzyMap projection mapping tool offers even more precise and flexible control over the shape, size and position of projected images.
  • Using IzzyMaps’s real-time modulation capabilites, you can create dynamic, video backdrops that respond to a computer operator’s cues or even to sensory input from the stage.
  • Control and cue lighting using MIDI Show Control commands or with an external DMX interface.
  • Utilize as many as four separate live camera inputs.
  • Isadora 2.0 now supports Blackmagic hardware directly, allowing high-resolution, low-latency video input.
  • Output to as many as six video projectors using a single desktop computer with multiple video cards. On a laptop, you output to three video projectors by using a Matrox Triple-Head-2-Go.
  • Create custom, lockable control panels that allow an operator to run the show without any chance to edit the patch itself. 

Interactive Performance & Installation

  • If you are new to the world of interactivity, our comprehensive tutorials will show you how to get started with a wide range of devices, from Arduinos, to Wii Controllers, to control apps like TouchOSC.
  • Isadora allows nearly every aspect of the media to be manipulated in real time using input from Open Sound Control (OSC), MIDI, Serial Data and more.
  • Easily sequence a series of video clips to accompany your performers on stage using our new Drag and Drop workflow.
  • Isadora’s scene-based structure is modeled on a traditional lighting board; transitioning to the next scene is as easy as a tap of the spacebar.
  • Each scene is a completely independent interactive setup, allowing both flexibility and clarity when organizing your show.
  • Integrate as many as four live video feeds with the performers onstage, optionally processing the live video using video effects, video delays or both.
  • Isadora can record and immediately playback video captured from one of the live camera feeds.


Video Effects for Post-Production

  • Isadora’s node-based interface allows you to link any number of video effects  modules in any order for unlimited creative control.
  • Record Isadora’s output to a QuickTime movie, and then import the result into your favorite video editor or other video production tool.
  • Unlimited input and output resolution – you can even render 4K movies if you take advantage of Isadora’s non-realtime rendering mode.
  • Input via Open Sound Control (OSC), MIDI, or even your mouse, allows you to improvisationally influence the visual result in real-time.

Video for VJs + Club Environments

  • We continue to offer video playback via Apple’s QuickTime, which remains the best system when it comes to scrubbing, jumping, and changing speed of video clips.
  • Isadora 2.0 supports the FreeFrameGL video plugin standard, bringing you high-resolution and speed. It also opens the door to a whole new world of third party video effects. 
  • Ceate custom control panels, with sliders, buttons, text, and more – control only the parameters you need for your set.
  • Organize hundreds of clips with the powerful Bin Picker Control so that you can select media by thumbnail, file name, or both.
  • Activate and deactivate any single module in real-time to finely tune your patch and maximize performance.

Features in Detail

Within Isadora, over 250 basic building blocks – called actors – are at your fingertips. Each actor has a unique function, from receiving a MIDI message to warping video imagery. By connecting these actors together, you can accomplish nearly any goal, from simply playing a video to creating a unique interactive system that responds to a live performer.

What distinguishes Isadora is its easy-to-learn user interface. Its unparalleled environment allows users to exercise ultimate creative control while simultaneously engaging in an organic and playful process of discovery.

General Features
  • Real time Video Processing Modules - Isadora has several built-in video processing effects, and now supports the highly efficient FrameFrameGL video plugin standard. You can choose from the  many video effects modules built into Isadora, or add third party FreeFrameGL effects. The Mac OS X version of Isadora 2.0 makes all of Apple’s CoreImage and Quartz Composer video processing plugins available as modules in Isadora.
  • Online Tutorials – Our online video tutorials will quickly allow you to use the program effectively.
  • A Manual That’s Actually Useful – Our manual provides a comprehensive look into every aspect of the program, including tips on getting the best performance from your computer
  • Control Panels – Create your own, custom user interface, including Dials, Radio Buttons, Sliders, and more. You can even use your own graphics to customize the look of the controls.
  • Custom Modules – Isadora allows you to create User Actors – a custom Isadora module built from numerous other Isadora modules. User Actors can be saved for use in other patches or shared with other users.
  • Snapshot Feature – Store and instantly recall every setting within a patch; invaluable for VJs.
  • Node-Based Programming – An Isadora “patch” is created by connecting multiple building blocks (called actors) together with a series of wires or ”patch cords.” This can range from simple setups – like connecting the output of a Movie Player to the input of a Projector to play a video – to far more complex constructions. One of the reasons novices like Isadora is that you they can start simply and gradually increase the complexity of their patches as they learn more.
  • Scene Based Structure – An Isadora show file is constructed from a list of Scenes. Like scenes in a lighting console, moving through Isadora scenes will transition from one “look” to the next. Often, that’s all you’ll need. But an Isadora scene can be far more than a simple cue. Each scene can define a completely distinct interactive response.
  • New Drag & Drop Workflow – Isadora 2.0 adds two fantastic new drag and drop options that allow you to quickly “rough out” the structure for a show. If you drag media file to the Scene Editor, Isadora will automatically import the file and create the modules needed to play it. Drag a media file to the Scene List and it will create a entirely new scene that plays that file. 
  • Live Video & Sound Input – Isadora accepts up to four simultaneous live video and/or audio inputs
  • Syphon/Spout Realtime Video Sharing – realtime video input from other applications via Syphon (Mac OS) and the newly released Spout (Windows).
  • External Input – Isadora accepts input from OSC, MIDI, serial (RS-232) devices and more. Learn more below under “Interactivity Features.”
  • Multiple Ways to Output Video – Isadora is primarily used to render in real-time to an external monitor or video projector. But you can also record Isadora’s output to a movie, or send the output to a high-quality Black Magic video card.
  • Integrated Projection Mapping – Isadora 2.0 now features an integrated projection mapping system. Learn more
  • Quick and Easy Compositing – Resize and composite multiple video images quickly and easily using the Projector actor – Isadora’s main video output module. This feature is invaluable when adapting a  show to new theaters while on tour.
  • Up to Six Independent Outputs – With a fast desktop computer and multiple video cards, project up to six independent images on six different surfaces from a single patch.
  • Video Output Capture – Record Isadora’s video output to a QuickTime movie. Turn on our our non-real-time rendering feature to render high-resolution output of complex patches – even as high as 4K – with perfect frame rates.
  • Multi-Channel Sound Output (MacOS X Only) – Send audio to a host of Core Audio compliant audio devices for high quality, multi-channel audio output.
  • Open Sound Control (OSC) – The OSC communications protocol has become a nearly universal standard for inter-application communication.  Using OSC, Isadora can easily speak with hardware devices like x-osc,  hand-held devices running apps like TouchOSC, and other applications like NI-MateOSCulator, vvvv, Pd, MAX and others.
  • MIDI – Explore a full complement of MIDI input and output modules.
  • MIDI Show Control – In Isadora 2.0 we’ve added MIDI Show Control input and output modules, allowing your patch to be controlled by, or to control, lighting consoles and other MSC compatible devices.
  • Serial Input/Output – Send commands to external that can receive commands via a serial port, including video projectors, video mixers and many other devices. (Requires an external RS-232 interface.)
  • Arduino – Using the serial input/output capabilities of Isadora, it’s easy to send and receive messages to Arduino via its integrated serial USB connection.
  • Video Tracking – Isadora has a built-in module called Eyes++ that allows you to track up to sixteen distinct objects in a live-video stream. Take a look at our Video Tracking Tutorial to learn more.
