Universal Scene Description (USD) is an efficient, scalable system for authoring, reading, and streaming time-sampled scene description for interchange between graphics applications.

USD provides for interchange of elemental assets (e.g. models) or animations. But unlike other interchange packages, USD also enables assembly and organization of any number of assets into virtual sets, scenes, and shots, transmit them from application to application, and non-destructively edit them (as overrides), with a single, consistent API, in a single scenegraph. USD provides a rich toolset for reading, writing, editing, and rapidly previewing 3D geometry and shading. In addition, because USD’s core scenegraph and “composition engine” are agnostic of 3D, USD can be extended in a maintainable way to encode and compose data in other domains.

Useful, everyday compositing plugins for Nuke

AFXSoftClip — Non-linearly reduce exposure. The algorithm was originally written for use in Eyeon Fusion. It’s much more intuitive than the Native Nuke implementation.

AFXToneMap — Exposure control, soft clipping, and dark contrast.

AFXMedian — Extremely fast median filter with sharpness parameter to reduce unwanted morphological changes and floating point size control. Faster than Nuke’s native median filter by an order of magnitude.

AFXChromaKey — Performs statistical analysis of chroma screen in LAB color space. Easily generate solid core mattes and detailed edge mattes. Invariant to lighting and grading changes due to per frame chroma analysis.

AFXDespill — Simply the best de-spill available. Output a spill matte to use as a mask for replacing de-spilled areas with a blurred version of the background or a reflection pass.

AFXAntiAlias — Morphological anti-aliasing to smooth ‘jaggies’ that are a very common problem with keying. Extremely useful for monitor comps.

AFXGlow — A beautiful glow.

Natron is a free and open-source node-based compositing software. It has been influenced by digital compositing software such as Nuke, from which its user interface and many of its concepts are derived.

Natron supports plugins following the OpenFX 1.4 API. Most open-source and commercial OpenFX plug-ins are supported.

The Academy Color Encoding System (ACES) is becoming the industry standard for managing color throughout the life cycle of a motion picture or television production. From image capture through editing, VFX, mastering, public presentation, archiving and future remastering, ACES ensures a consistent color experience that preserves the filmmaker’s creative vision. In addition to the creative benefits, ACES addresses and solves a number of significant production, post-production and archiving problems that have arisen with the increasing variety of digital cameras and formats in use, as well as the surge in the number of productions that rely on worldwide collaboration using shared digital image files.
