NAB Show, Las Vegas – To provide enhanced creative capability within on-line grading and finishing, SGO has developed “Spatial Isolation Toolset” for its Mistika DI, Grading and Finishing system for Mistika version 8.2.
In both 2D and Stereo 3D finishing, it is common for multiple objects to brought together from separate creative systems, using masks, object IDs, positional information, travelling mattes, and so forth, and in the case of live-action Stereo 3D, associated z-depth maps. Unfortunately, it is standard practice for such information to be dropped before entering the on-line grading and finishing, especially when the number of objects being combined is large in number, resulting in a single-plane image with no ability to re-adjust objects independently within the grading and finishing stage of the project workflow.
SGO’s new Spatial Isolation Toolset works with all the associated additional object information, enabling the simple selection of any object or group of objects, providing total interactivity with respect to blending objects together through the use of Mistika’s advanced grading tools.
A colourist can use any object selection options by single clicking any elements or part of an element, correcting only object surfaces pointing in certain directions, or separate objects by a z-depth range selection, all of which can be combined with traditional object isolation modes, such as windows and colour or luminance range selection, but now with total object isolation accuracy.
What Spatial Isolation offers to the colourist is not compositing – it is object separation inside the colour grading workflow, using the information provided by the previous effects and compositing systems. This means it is no longer necessary to spend time attempting to fine-tune objects integration with their surroundings with the slow and non-interactive capabilities provided within effects systems, instead allowing the real-time and fully interactive capabilities of Mistika to creatively light and grade 3D animation objects sympathetically within their final surroundings.
When working with Stereo 3D footage the associated z-depth map can just as easily be used to perform object and image plane isolation, allowing the colourist to perform far greater creative manipulations, from grading and colour correction, to defocus, and re-lighting, further enhancing the reality that Stereo 3D can bring to the big screen.
“SGO strives to bring unique and unmatched creative capabilities to its customers, and Spatial Isolation is a perfect example of SGO’s ability to think beyond the normal constraints associated with grading and finishing”, added Geoff Mills, Sales Director, SGO.
