IRIDAS DualStream Goes Mainstream at Threshold and 3ality

Stereoscopic Playback for Review and Color Grading in Postproduction
Munich: August 16, 2007 … IRIDAS, who introduced the first software solution for uncompressed stereoscopic playback in 2002, is seeing increasing use of its DualStream technology for HD, 2K, and higher resolution playback in postproduction facilities such as Threshold Digital Research Labs and 3ality Digital Systems. Originally only available with special stereoscopic versions of FrameCycler, DualStream is now an optional add-on module for all current versions of FrameCycler as well as SpeedGrade HD and DI.


FrameCycler with DualStream provides uncompressed playback of stereoscopic content and supports most 3D display technologies. It has been used extensively in areas as diverse as public presentations, scientific research, and, of course, postproduction. “The stereo versions FrameCycler helped us a lot,” said George Johnsen, CTO at Threshold Digital Research Laboratories who have been using IRIDAS’ DualStream technology since 2003.

“One of the most difficult things about making 3D in film is the faith you have to have when the images go into the camera,” explained Johnsen. “When working 3D in digital, either live action or animated, that guesswork and dependence is taken away by being able to see the images in real-time. Uncompressed stereo is the only way to work quickly and cost-effectively. That is why FrameCycler has been so important for us.” (read the complete interview with George Johnsen at

SpeedGrade DI with DualStream plays two stereo channels in virtually any industry file format and offers real-time grading, masks, pan-and-scan, .Look and LUT support, and more. Colorists can grade each “eye” (channel) individually as well as applying overall grades to both. “With SpeedGrade DI and DualStream I can finally work with all of the components of a stereo movie in the same workspace,” said Price Pethel, director of postproduction at 3ality in Burbank, California. “Color grading all of the stereo elements and being able to see content in real-time the way the audience will see it is crucial. With this technology, I can now do all of my film finishing in stereo.”

IRIDAS’ DualStream stereoscopic module is available for all 2007 versions of FrameCycler as well as SpeedGrade HD and SpeedGrade DI. Current owners of these applications can upgrade to DualStream at any time. For more information visit or contact IRIDAS at +49 89 330 35 142, or IRIDAS USA at (818) 951-8927.

IRIDAS pioneered desktop film-resolution playback in 2001. Its FrameCycler products are now the industry standard for frame-based image review. In 2003 IRIDAS introduced the first non-destructive color correction application. Today SpeedGrade and FrameCycler provide the critical links in an end-to-end pipeline for uncompressed content and color metadata. IRIDAS’ applications are used by filmmakers around the world and most major animation and postproduction houses. IRIDAS is an independent, privately held company headquartered in Munich, Germany.
