Resumen del manual
It has even been recognized and honored by the Academy of Motion Picture Arts and Sciences (A.M.P.A.S) with a Technical Achievement Award in 2002. From the time of its first introduction, the ARRILASER has had the ability to record in true 4K resolution and has continually adhered to the latest standards, such as DCI (Digital Cinema Initiative) specifications. The original Standard ARRILASER is now just one in a range of five different versions that meets the requirements of various postproduction business models. The ARRILASER HD/DI represents an entry level system for emerging markets and start-up companies, while the ARRILASER Speed Performance and Speed twoK are mid-range options. At the top of the range are the ARRILASER HighSpeed twoK and HighSpeed Performance models - the ultimate choice for clients who cannot compromise on speed of operation or image resolution. 2002 Scientific and Engineering Award (Academy of Motion Picture Arts and Sciences) for the design and development of the ARRILASER Film Recorder. © A.M.P.A.S. ® ARRI DIGITAL INTERMEDIATE SYSTEMS | | ARRILASER 3 ARRILASER Models HD/DI Speed twoK Speed Performance HighSpeed twoK HighSpeed Performance Speed specification Sec/frame Sec/frame Sec/frame Sec/frame Sec/frame HD 3.4 1,9 1,9 approx. 1.0 approx. 1.0 2K 1:1.85 3.2 1,7 1,7 2K Fullap 4.1 2,2 2,2 4K 1:1.85 – – 2,9 – approx. 1.5 4K fullap – – 3,8 Intermediate film stock • • • • • Camera negative stock Optional Optional Optional Optional Optional Resolution 2K • • • • • Resolution 4K – – • – • On-the-fly image processing • • • • • ARRICUBE color management Optional Optional Optional Optional Optional Optional module HD, Native Academy, 3-Perforation The ARRILASER is designed as a modular system, so each model is fully upgradeable. Please refer to the upgrade matrix at the end of this brochure. 4 STATE OF THE ART TECHNOLOGY Laser Light Source Three solid state lasers are used in the ARRILASER, producing monochromatic light beams in the colors red, green and blue. With a perfect Gaussian shape, very long life expectancy and minimal size as well as power consumption, they are the key to the ARRILASER’s unrivalled image quality. The data for each color channel and pixel is fed to an Acousto-optical Modulator (AOM) as a light intensity value, according to which the beam intensity is controlled. The AOM translates the digital data of each pixel into beam intensity in less than 17 nanoseconds. Deflection System Moving parts on the ARRILASER are designed to sustain a minimum of wear. A new aerostatic bearing motor, which encounters no mechanical friction during operation, is used to achieve the speed required for the deflection of the beam. Line by line is written on film in an ultra precision linear stage. A linear induction motor moves the stage through direct magnetic induction without any additional moving parts such as gears. ARRI DIGITAL INTERMEDIATE SYSTEMS | | ARRILASER 5 Camera and Film Transport The increased CPU capacity of the new ARRILASER camera electronics enables more sophisticated control of motors in the camera and magazines. In addition, the display and the camera buttons now offer expanded and improved features. Control of the ARRILASER using the display and the camera buttons has been simplified to allow more intuitive camera operation and film loading. The two camera buttons now function as soft keys and can be used to make all necessary setup entries. At every stage the display indicates exactly what will be achieved by pressing either of the buttons. The operator can now specify what film type/emulsion has been loaded into the feed magazine. With these parameters in place, the ARRILASER is able to calculate the amount of remaining negative in the magazines and display these quantities in either feet or meters. This gives the operator an accurate idea of the remaining film stock in the feed magazine and therefore minimizes film wastage. TOP LEVEL DESIGN HIGH PERFORMANCE Internal Electronics and Processing Newly designed electronics now allow the bit depth of the internal processing to be raised from 10-bit to 16-bit, thereby rendering additional bit depth conversion unnecessary. This enables the processing of all 16-bit image data without any compression, from the file loader all the way down the data path to the D/A converter (digital-to-analog converter). The implementation of commonly-used FPGAs (field-programmable gate arrays) on the electronics board results in improved data handling and eliminates image transfer errors. In combination with the CAN bus protocol, this speeds up both internal communication and processing, while also making the system safer. ARRILASER Software The new ARRILASER Trillian interface, which replaces the current AL GUI, offers unprecedented flexibility of operation and is itself capable of speeding up daily operations. Trillian’s main advantage is its ability to control and operate multiple lasers with the ease of just one application. Job Edito...
