Mayhem in Consumer Delivery

“The number of players delivering movies is enormous,” said Microsoft’s Richard Doherty, who moderated a panel titled Consumer Delivery: Mayhem. “However the services differ.”
Panelists shared their strategies and views:

Morgan Fiumi, Deluxe Digital Studios:
–“People have underestimated the complexity of getting the assets organized. … A lot of the assets need to be prepared for delivery”
–“We have added some services that enable metadata to be searchable”

Brad Collar, Warner Bros.:
–From a tech POV, we have two buckets: Core video assets and interactivity. On the core asset side, we developed an internal system (with a) mezzanine format in a digital vault. On the navigation side, sub buckets include operation using a touch interface and a mouse.
–Codecs? “H.264 is very efficient, but it is so fragmented out there.”
–“Settled internally on about 12 file formats for metadata. There are discussions about standards”

Ellen Goodridge, Sony Pictures Entertainment:
–“Without standards, it is really hard to scale. In the last couple years, it has become even more complex. The logistics of sending mezzanine files in different specs can be very complicated and cause a lot of stoppages in the overall supply chain. We think UltraViolet is a really great long-term fix for the supply chain.”
–We want consumers to want own (their content). We have to get (quality) right to grow this business.

Chuck Parker, Technicolor:
–“We try to encourage our customers to standardize (codecs) as much as possible”
–Do consumers care about quality? “My view is consumers have an expectation of less that DVD quality.”
–“Contextual metadata is the next frontier in this space”

Examining 3D Subtitling

Jonathan Jenkyn, project specialist and software developer at Screen Subtitling, gave a short presentation on subtitling for stereographic media.

Challenges:
–“You can’t subtitle the same in 2D as in 3D. The 2D depth cue wins, and you are going to cause headaches, nausea.”
–Placing subtitles in a standard position in front of the imagery: Subtitles may be a very long way away from the material (in certain shots). Eyes will tire from the need to refocus.

Jenkyn suggested that subtitles match the parallax of a scene, matching the focal object or foremost object.

–Display size matters. Material must be re-mastered or adjusted for display types.
–“It takes about four times as long to do 3D versus 2D subtitling”
–“Can it be down automatically? … It can if you use disparity mapping. pushing broadcast quality through disparity mapping the results can be poor”

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.
