Phantom 65-Z3D System for single camera 3D recording

4.25.2011

[by StereoscopyNews.com]

3D recording with a single Pro camera is now possible thanks to the ZEPAR 65-Z3D lens put in front of the Phantom camera and its 4K sensor.  Recording is done in full dual-Full HD side-by-side.

Interocular distance is adjustable from 24 to 26 mm, a sligthly limited range, however….

The solution offers an ultra-lightweight camera+optics module for hand held, Steadicam and B camera companion.

Quantel Intros Stereo3D Toolset

4.25.2011

[by Below the Line News staff]

Quantel demonstrated new Stereo3D tools for its post and broadcast products at NAB that will help speed stereo3D work through the suite by cutting the time spent identifying and fixing errors in stereo 3D shots. The company is now offering the new Stereo3D toolset as a standard feature on all V5 eQ, iQ and Pablo systems.

 

Geometry errors between the left and right eye images are almost inevitable with the use of two cameras when capturing stereo 3D. Fixing these errors is essential for high-quality stereo, but undertaking this manually can be a very time-consuming process. The new Geofix tool automates the process, making geometry fixes fast and accurate. Geofix first analyzes the two images then applies translation, rotation and corner-pin DVE processes to correct errors. The result is less time spent on fixing stereo 3D material.

A new Stereo Measurement Console adds a suite of tools that makes monitoring and working with stereo 3D faster and more productive. The console includes live on-screen histogram and vectorscope displays to help identify differences between eyes. The console also includes a measurement tool for disparity, which makes it easier to meet the typical specifications being introduced for 3D channel content by broadcasters. There is also a new overlay and cursors on the main outputs, making it straightforward to see exactly where objects sit in 3D space.

[Flip on file import or conform is another useful new time-saving tool that allows signals to be flipped or inverted on import/conform. This means that images captured with mirror rigs do not need further correction before they can be viewed in stereo.

The Stereo3D Auto Color Balance tool has been improved with gamma adjustment to deliver a better match between left and right eye signals.

“Making great Stereo3D depends on getting the basics right quickly and efficiently,” said Steve Owen, Quantel’s director of marketing. “The new Stereo3D tools help do just that, so that more time can be spent on creative tasks. We have already had some great feedback from early users of some of these new tools.”

Geofix has already been released and the remainder of the tools will be delivered in a v.5 software release in May.

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.
