Gorilla Group Chooses Big Pic Media’s MTI Film Cortex for New 4K HDR Mastering Suite


MTIFilmGorillaLogoCardiff-based film and video post production house Gorilla has chosen an MTI Film Cortex Enterprise mastering and validation system for a new 4K HDR mastering suite at its recently expanded GloWorks facility.

Supplied by MTI Film distribution partner Big Pic Media, the Cortex forms part of Gorilla’s investment in new 4K HDR technology.

“Cortex Enterprise gives us all the tools we need to take our creative department’s work and produce perfect masters to the very specific requirements of the SVOD and broadcast channels for 4K and HDR content,” says Gorilla Group Managing Director Richard Moss. “We use it to package the image and audio content and ensure we provide the necessary metadata in ancillary files to conform to the specific needs of the studio or broadcaster. What our operators like about Cortex is that the user interface is based on an NLE timeline and has a very logical step-by-step process to ensure nothing is missed. It also has templates for nearly every studio or broadcaster we supply, making our work much more efficient and accurate. A unique feature of Cortex is dead pixel detection and correction. MTI Film has perfected these algorithms over the past 30 years in developing restoration tools, making the process of detecting and fixing dead pixels fast and efficient. Once we have made a package we drop it back into Cortex for validation. Cortex also performs automated checks for HDR levels, HLG, HDR10, Dolby Vision and Dolby Atmos.”

“We worked closely with Gorilla to evaluate Cortex, ensuring it met and exceeded today’s requirements,” adds Big Pic Media MD Adam Welsh. “We also demonstrated MTI Film’s commitment to keep abreast of evolving requirements and continually develop the product.”

Gorilla’s new 4K HDR Mastering Suite

MTI Film Cortex products include solutions for on-set and post with a full-feature dailies application. These include IMF, DCP, AS-02 and Dolby Vision packaging, multiple quality control modules, video measurement tools, IMF validation and resolution upconversion. Each module includes enhanced editing capabilities. Cortex v5.2 Enterprise Edition is now officially certified for use with Dolby Vision Content Mapping v4. It  includes the ability to package Dolby Vision IMFs and to import/modify/export Dolby Vision XML files and MXF files for both Dolby Vision CMv2 and Dolby Vision CMv4. Cortex runs on Microsoft Windows 7 or Windows 10 and uses one or more NVidia GPUs.

Vicon Introduces Mobile Mocap at SIGGRAPH

Motion capture systems developer Vicon is previewing a futuristic new “Mobile Mocap” technology at SIGGRAPH 2011 in Vancouver. Moving mocap out of the lab and into the field, Vicon's Mobile Mocap system taps several new technologies, many years in the making. At the heart of Mobile Mocap is a very small lipstick-sized camera that enables less obtrusive, more accurate facial animation data. The new cameras capture 720p (1280X720) footage at 60 frames per second. In addition, a powerful processing unit synchronizes, stores, and wirelessly transmits the data, all in a tiny wearable design.
