Iridas has developed a native stereoscopic 3D workflow for films and TV programmes being shot using the Arri Alexa digital film camera.

The innovation makes use of Iridas’ DualStream NX stereoscopic review technology and its SpeedGrade and FrameCycler 2010 family and allows users to instantly review Alexa shot stereo 3D footage in the field and make use of real-time geometry alignment and colour matching in a stereoscopic timeline.  

Lin Sebastian Kayser, the chief executive of Iridas, said: “This feature represents the culmination of years of engineering and stereoscopic development expertise that has enabled a 3D production workflow that works flawlessly with the equipment our customers most want to work with, like the innovative new Alexa cameras.”

DualStream NX features tools for automatically correcting geometric misalignment and eliminate color differences between left and right eye streams.

How it works:

  • Alexa shoots ProRes 4444 12 bit files to Sony SxS cards;
  • Iridas SpeedGrade and FrameCycler 2010 decode two streams of Alexa ProRes 4444 material in real time, which means they are available for instant playback and review.
  • Users review the stereo streams and, with the push of a button, geometrically align and color match in a true stereoscopic timeline. 
  • Material can be rendered for offline dailies or directly edited in Final Cut Pro and Avid systems, then conformed from EDLs for final color grading and depth grading.
  • For users working with other workflows, ProRes 4444 files can also be transcoded to frame formats, including DPX, in full 12-bit bit depth. 

The Iridias SpeedGrade and FrameCycler 2010 family of 3D production solutions are available immediately.
