ETC Releases White Balancing Tutorial for Virtual Production

ETC@USC has posted a tutorial that offers best practices for white balancing during production on a curved wall LED volume stage. Due to the growing number of LED volume and backing wall applications emerging worldwide, many critical color calibration issues have resulted. The informative tutorial — authored by cinematographer Tim Kang from Quasar Science with support from producer Erik Weaver from ETC — provides cinematographers and production teams with a simple graphical guide that breaks down the problems between the camera and its LED wall perception, while specifying different means to implement solutions. The Virtual Production White Balancing Tutorial is now available on the ETC site.

ETC’s CES 2024 Report: Creators, Displays, and AI Innovation

CES 2024 attracted more than 135,000 attendees to Las Vegas where 4,300 companies filled 2.5 million square feet of exhibit space. Technology that empowers creators, a new generation of displays, and the promise and peril of artificial intelligence dominated the show. After several years of incremental advances, market development built on maturing technology, and over-hyped trends, this year felt different with an energy that suggests the beginning of a new era. Among the major themes were embedded Al, vehicle tech, digital health, screens and XR, and numerous policy and regulation topics. ETC@USC attended the conference for live reporting on products and services. Our post-show report features extensive coverage and perspectives related
to key creative, business, and technology areas.

Specification for Naming VFX Image Sequences Released

ETC’s VFX Working Group has published a specification for best practices naming image sequences such as plates and comps. File naming is an essential tool for organizing the multitude of frames that are inputs and outputs from the VFX process. Prior to the publication of this specification, each organization had its own naming scheme, requiring custom processes for each partner, which often resulted in confusion and miscommunication.

The new ETC@USC specification focuses primarily on sequences of individual images. The initial use case was VFX plates, typically delivered as OpenEXR or DPX files. However, the team soon realized that the same naming conventions can apply to virtually any image sequence. Consequently, the specification was written to handle a wide array of assets and use cases.

To ensure all requirements are represented, the working group included over 2 dozen participants representing studios, VFX houses, tool creators, creatives and others.  The ETC@USC also worked closely with MovieLabs to ensure that the specification could be integrated as part of their 2030 Vision.

A key design criteria for this specification is compatibility with existing practices.  Chair of the VFX working group, Horst Sarubin of Universal Pictures, said: “Our studio is committed to being at the forefront of designing best industry practices to modernize and simplify workflows, and we believe this white paper succeeded in building a new foundation for tools to transfer files in the most efficient manner.”

This specification is compatible with other initiatives such as the Visual Effects Society (VES) Transfer Specifications. “We wanted to make it as seamless as possible for everyone to adopt this specification,” said working group co-chair and ETC@USC’s Erik Weaver. “To ensure all perspectives were represented we created a team of industry experts familiar with the handling of these materials and collaborated with a number of industry groups.”

“Collaboration between MovieLabs and important industry groups like the ETC is critical to implementing the 2030 Vision,” said Craig Seidel, SVP of MovieLabs. “This specification is a key step in defining the foundations for better software-defined workflows. We look forward to continued partnership with the ETC on implementing other critical elements of the 2030 Vision.”

The specification is available online for anyone to use.
