SGO Mistika Stereoscopic 3D Tools
SGO Mistika provides 3D stereo capabilities well beyond dual output. A complete 3D stereo workflow is provided, including:
- Dual HD SDI stereo output in realtime, even for HD and 2K uncompressed sources with pan & scan, 3DLUT and colour grading applied.
- 3D Interactive parameter adjust: Thanks to the new stereo groups, all modifications to any effect can be adjusted interactively in the stereo output, without the need to “copy to the other eye”. You can apply an effect to both eyes or to one eye at any moment.
- Context sensitive evaluation: You can be working with dual eye stereo feedback and then change to single eye mode with just one button; The feedback of all stereo groups will be switched to single-eye, in order to work with them in the 2D reference display until you decide to switch back to the stereo output.
- Amazing new tools to compare the two clips, to fix the colour and luminance differences and to adjust the distance between the two eyes based on Mistika exclusive motion estimation techniques.
- Advanced tools to correct image deformations that are typical when using cameras with mirror rigs.
- Match grading tools, to correct colour differences between eyes.
- 3D compositing in a true 3D environment with 2 cameras (one for each eye) is also provided. The second camera is managed automatically at a predefined distance. You can place text and flying logos in a 3D scene, or even a 3D chroma key into a dual eye 3D background.
- Geometric correction. For easy adjustment of deformations produced by mirror camera rigs and other geometric differences in terms of X and Y scaling, rotation, and position.
- Equaleyes provides fully automated functions for correcting discrepancies between left and right images, caused by differences in cameras, lenses and stereo rig systems.
“It would have been impossible to correct that amount of material in such a short space of time, to Sky’s exacting standards, on any other system. Mistika remains without a doubt, the fastest and most productive finishing and workflow system around.”
- BSkyB’s lead stereographer Francisco Ramos, on The Royal Wedding in 3D and the use of Equaleyes.
- A single click permits to switch between many different stereo modes, both for interactive visualization and for rendering to image files.
These stereo modes support all standard 3D Stereo displays, and they also provide advanced comparison tools to adjust differences between the two eyes.
The correction of these differences is essential for 3D stereo post production. These differences occur for different reasons, like 3D rigs in movement ( different movements and vibration patterns of both cameras), mirror rig for a vertical mounted second camera (geometric deformations and luminance ramps), light sources producing light differences between the two lenses, the internal differences of both lenses, convergence errors, focus differences, etc.
Mistika 3D stereo modes:
Anaglyph colour: (for old style glasses with red and blue/green filters)
Anaglyph “Black & White”: (similar to previous mode, but removing chroma information to avoid convergence errors due to phase displacements between colour channels).
Interlaced: For 3D displays requiring each eye image in one field.
Dual Link: Each eye is sent to a different SDI-HD 1920×1080 output signal (the best quality format)
Side by side: Each eye stretched to one half of the image, for 3D displays requiring this format.
Right only / Left only: ( 2D display of the user selected eye)
Checkerboard: The image is subdivided into small squares, alternating pieces of each eye in a checker board pattern. This permits to study local differences in chroma and luminance to fix them easily.
Mix: A mix of both eyes, for general visual comparison.
Difference: Grey-scale or false colour representation of the differences between the two eyes. To study convergence differences and other issues.
- 3D Stereo capture and playout from/to HDCAM-SR and other dual link recording VTRs
In addition, Mistika can automatically encode/decode two YUV 422 10bit signals into one consecutive file, which avoids the double seek times required by two files and provides excellent disk speed performance.
- Collaborate: 3D player for external sequences out of the Mistika storage. You can link DPX, tga, AVI, MXF, and Quicktime files, and other external sequences located in other places and play them to the stereo output without any import or conversion process. In addition, the Mistika advanced pre-read buffering and disk access priorization tools permit to sustain realtime stereo playouts for external files even in the most difficult situations, because it can manage the typical big I/O peaks that usually appear in any shared storage under heavy traffic conditions.
