Testing High Frame Rate Equipment
By Jean-François Nivart, CEO at Image Matters
Are higher frame rates just the latest hot technology fad for the entertainment industry or is there the promise of real benefits for film makers and audiences? Today, the moving picture industry still continues to work with its historical 24 frames per second. At this speed, rapid movements can’t be reproduced accurately: there is too much movement between successive frames, and to avoid stroboscopic effects cinematographers use motion blur. At 24 frames per second, there are very few pictures to describe rapid trajectories, and motion blur helps provide the sense of movement direction. So most of the pictures we see on our displays are actually blurred! This is a strange state of affairs in a market that is evolving through high definition and moving toward 4K. Audiences are being asked to accept blurred pictures, while our eyes are getting used to highresolution computer screens with sharp and high-contrast images. Cinematographers are doing a great job using the current limitations of the medium to enhance their art: being constrained to 24 frames per second, they have developed the very artistic cinematographic look of movies. Using motion blur and depth of field as narrative tools, the story tellers convey vibrant emotions. But – what if there were no technical limitation at all? Digital projectors, LCD, plasma and LED panels are now capable of rendering much higher frame rates – 50, 60, 120 and more progressive frames per second. Cameras, recorders and players are also capable of much higher frame rates. As a result, famous cinematographers are today pioneering production at 48 or even at 60 frames per second and per eye. Their efforts are supported by a SMPTE 21DC study group on high frame rates co-chaired by Michael Karagosian of MKPE Consulting, and cinematographers Kommer Kleijn SBC and David Stump ASC. Now a consortium of technology providers including Image Matters, intoPIX, MikroM and Virident has come together to conduct a series of tests in early June 2012 in Burbank, CA area. These tests, conducted in collaboration with studios and the creative community, will measure the minimum JPEG 2000 codestream bit rate needed for high frame rate content to reach the visually lossless quality demanded by digital cinema applications. The experimental equipment set up will enable playback of JPEG 2000 codestream bit rates higher than 1Gbps (more than four times the current DCI specification). The decoded 2K images will be transmitted to a single projector at a frame rate of up to 120fps (i.e. 60fpe for stereoscopic 3D content). To speed up the process and to allow the easy production of multiple varieties of encoding, the equipment will also be capable of encoding high frame rate content from uncompressed files in near real time. The technology used for the test will consist of one server incorporating four Virident FlashMAX boards and one intoPIX JPEG 2000 PRISTINE-P4 board. The PRISTINE will playback the decoded codestream on four 3G SDI links to the MikroM IMB inserted into the projector. The MikroM’s IMB will receive the four 3G-SDI links and pass the uncompressed image data directly to the projector backplane. Image Matters will provide project coordination and integration. The integration has enough headroom to allow the addition of extra components to achieve higher bit rates and/or higher frame rates. ■

Deltacast Debut Two New Capture Cards
Deltacast has launched compact multi-channel SDI capture cards
Deltacast have introduced the DELTA-hd-elp-d 80, with eight HD SDI inputs and the DELTA-3G-elp-d 40, with four 3G SDI inputs. Both cards use PCIe GEN 2 technology to ensure the simultaneous transfer of up to HD SDI streams to the PC on a single PCIe slot. The company successfully implemented the design on a half-length low-profile form factor, targeting 1RU platforms. This implies the use of DIN 1.1/2.3 connectors instead of the classical BNC connectors. Both products will be supported by the extremely popular VideoMasterHD OEM SDK. cards, with more channels and more performances. Our move towards compact cards is an important step corresponding to market expectations.”

DELTA-3G-elp-d 40 – four inputs

Comprehensive Portfolio
Deltacast is dedicated to developing and manufacturing state-of-the-art products for the professional digital video market. The current portfolio offers seven interface card families: the DELTA-asi, DELTA-sdi, DELTAhd, DELTA-3G, DELTA-key, DELTAdvi, and DELTA-codec. With more than 60 available cards, Deltacast offers a comprehensive portfolio for professional OEM video development, to create custom solutions for compressed and uncompressed video systems, under Windows and Linux. Deltacast also works with OEMs to customise development. ■

Significant Milestone
“This is another significant milestone in our history” said Christian Dutilleux, CEO of Deltacast, he added: “Once more we take profit from the technology progress to propose new
