In a linear workflow, when the original data came from a digital camera or are scanned by a telecine the post production will be done with linear data. The unmodified images are displayed on the monitor or on the digital projector for the colour correction. In this case the images will be converted by the ARRICUBE node in the image processing engine of the ARRILASER. The colours in the film projection will then be matched to the colours on the monitor. Color management will be applied to the images on the fly and thanks to the multi thread programming of the ARRILASER software the recording speed is not influenced.
The ARRICUBE for Video Look is available as an option for all ARRILASER models.
Most DI project nowadays are done with a logarithmic workflow. In this case the incoming data will be logarithmic. The acquisition is done on film and the data are scanned with the ARRISCAN. The ARRICUBE is used in form of a 3D lookup table, which changes the display on the monitor or the digital projector in the way, that the colours look like they will look in the film projection. The 3D lookup table can be loaded into colour correction systems or projectors of one of our ARRICUBE partners.

To provide a good match between display and film projection the following parameters have to be taken into account: monitor/display characteristics and calibration, surrounding light conditions, film projection lamp and screen reflection, print film characteristic and printer lights, negative film characteristics and calibration as well as recorder characteristics. ARRI´s generic 3D Look Up Tables use standards wherever available in order to change some of these variables into constants.
For customers, who like to diverge from those standards, ARRI offers a Customized Service for the ARRI Color Management System. Measurements will be taken from the digital projection as well as from the projected print film in the customers environment and a custom designed 3D Look Up Table will be generated.
