Media project saved by Isadora; provides a graphic programming environment for managing digital media and external devices; allows for interactive control of digital media, with an emphasis on the real-time manipulation of digital video; supports audio, video, and MIDI data.

Isadora projects are created using basic building blocks, called actors, that are available within the Isadora environment. Actors may perform basic functions like waiting for MIDI events, or advanced functions like warping video clips. Actors can be connected together to instruct the program how to respond live events.
