opens up new vistas for many clients.
The ARRISCAN is a workhorse that can handle short-form projects, long-form docu-
mentaries and feature lms, digital dailies and archiving work. The applications are numer-
ous, ensuring a short return-on-investment cycle.
Flexible Customization
The parameters of any given application can easily be set and dened with the ARRISCAN
software. Whether a client wants to have maximum quality scans for visual effects shots or
just needs a quick preview of the lm roll, the parameters are all controllable and adjust-
able, depending on the application.
The level of user adaptability and exibility of the ARRISCAN is unequalled in the market.
Efciency & Productivity
The ARRISCAN enhances postproduction workows by reading keycode, importing edit
decision lists (EDLs), managing jobs efciently and utilizing easy-to-use Linux-based
software. The integrated touchscreen display allows for rapid lm loading and minimal
set up time. With a competitive scanning speed the ARRISCAN reduces costs per frame
dramatically and has become the preferred choice for digital dailies applications.

Digital Dailies
In recent years more and more production companies have come to see the disadvantages of a typical
telecine-based workow. Colors, geometries and the complete look of the ofine image data can be dra-
matically different to how the nal result will appear after high resolution scans. Very often the director
or DoP will be puzzled by inconsistencies between the ofine cut and the nal online edit.
With the ARRISCAN these inconsistencies need no longer exist. Dailies can be scanned at a reduced
resolution very quickly and stored on disks for further use. Once the edit decision list is available the lm
can be scanned at a higher resolution and higher dynamic range, and the results will match the color
and geometry of the lower resolution dailies.
The ARRISCAN has opened up dramatic workow enhancements:
n Dailies and high resolution scans will match in color and geometry
n Grading of digital dailies can be easily reproduced in the nal grading process
n Digital dailies data can be used for direct low res distribution
n 2K dailies data can even be used for nal results
n Data can be directly stored on mass storage, with no transfer
engine or color space conversion required
n One device (ARRISCAN) can be used for dailies and nals
Digital Dailies Base Package
In addition to these advantages, the ARRI team has developed
specic features for the digital dailies workow and made them
available in the Digital Dailies Base Package option.
In this software update, the ARRISCAN operator will get a live
preview while winding. This preview is a monochrome image
showing the content of a lm reel 'on-the-y'.
The base package also includes an additional speed increase:
n 1.5 fps for 6K oversampled to 4K
and 6K oversampled to 2K
n 5 fps for 3K oversampled to 2K

Archive & Restoration
Millions of meters of lm are stored in lm archives worldwide. Some material is
in very good condition, but as lm ages it can show signs of becoming damaged,
shrunken and brittle. It is especially for this kind of material that the ARRISCAN has
the option to be operated in various extra gentle lm transport modes.
Mechanical pin registration can be deactivated and the transport speed slowed
down to cope with certain types of damage. The LEDs inside the ARRISCAN are
known as a cold light source so there is no thermal stress on the lm, which is a
crucial requirement when dealing with nitrate lm for example.
The current features at a glance:
n Extra safe lm loading procedure
n Transport speed can be decreased for brittle material
n Controllable lm tension
n Mechanical pins can be retracted for shrunken lm
Restoration application using ARRISCAN data in up to 4K resolution.
For color lmstock:
n corrected image by Kodak Digital ICE + IR information
n severe artefacts are not corrected but indicated in the defect matte

Commercials
Most commercials are nished in HD resolution and therefore do not require resolu-
tions higher than 2K. The ARRISCAN Speed3K model features a maximum scanning
resolution of 3K (oversampled to 2K) and is designed for precisely these kinds of
applications. It delivers high end image quality at a superior speed and ts seamless-
ly into a tapeless workow.
Scanning in 2K resolution and simultaneously storing 1K proxies allows for a
highly paralleled workow. The 1K proxies are used for best-light color correction
because many agencies like to work with material that already has the ‘look’ of the
commercial in the edit suite. The deliverables for the edit can be generated traditi-
onally as tapes or rendered in DNxHD format, which allows for fast import into an
Avid system.
What makes this workow so interesting is the fact that visual effects work and
color grading can begin before editing is nished, because all the footage is present
on disks with the full latitude and in high resolution. Tape-to-tape color correction
processes such as a rst transfer become obsolete and the time that is apparently
lost by using a non real-time lm scanner can easily be regained.
The advantages for a commercials workow at a glance:
n Complete negative information will be transferred to digital data
n No artist is necessary for the scanning processes
n Full grading can be done on the scans
n No additional equipment like a transfer engine is necessary
n Oversampling delivers sharper SD images
n Special ARRISCAN Speed3K model is available

STATE OF THE ART
TECHNOLOGY
Illumination
The key to excellent color reproduction is the illumination system. For a light sour-
ce the ARRISCAN uses an array of LEDs, which are characterized by low power
consumption, high efciency, excellent color separation and great durability. LEDs
guarantee perfect image quality and place the lowest possible strain on the lm by
minimizing thermal dissipation.
The illumination is digitally adjusted and optimized to suit different lm stocks
via a closed loop regulation system. In addition LEDs will not change their spectral
characteristics; there is no drift and no ageing.
A database keeps track of the illumination parameters used with a given lm
stock and the results achieved by an ARRISCAN will be repeatable over time with
different machines

Infrared Against Scratches
Besides the RGB illumination unit, the ARRISCAN uses an additional
infrared illumination channel to identify lm defects. Since lm color
dyes are transparent for infrared light, the ARRISCAN sees only lm
defects (such as dust, lint and scratches) in the infrared image, which
means such defects can quickly be isolated and corrected.
Kodak’s DIGITAL ICE Technology uses the infrared channel of the
ARRISCAN to automatically remove dust, scratches and blemishes from
a scanned image. First, DIGITAL ICE identies all defects in the image
and then reconstructs the true color information wherever possible;
the number of blemishes is thereby reduced signicantly. Remaining
defects that are too severe to be reconstructed perfectly are marked
in an additional defect map, which can either be stored as a matte or
embedded into the scanned image. Downstream workow productivity
both in terms of labor and time is signicantly improved.
Optimized for the ARRISCAN image processing chain, DIGITAL ICE
is seamlessly embedded into the data path and is applied to the images
on-the-y while scanning.
The DIGITAL ICE package is available as an additional option for the
ARRISCAN.

Image Capture
For capturing the image a custom-designed CMOS area sensor is utilized.
CMOS technology presents several advantages: high speed performance
by parallel data outputs, exible output modes through active-pixel-
technology and lm protection through short exposure times.
The ARRI-designed CMOS chip sensor is optimized for speed and for
quality. It is a robust 35 mm area sensor with low power consumption
and can be operated at much higher speeds than traditional sensors.
Combined with the LED light source it represents an ideal method of
capturing high quality images.
Extended Dynamic Range
When utilizing the 'double exposure' method, each frame of lm is
exposed twice at different light levels. Both of these images are digitized
and composited into one output image. This method is used mainly for
lm stocks with a high density range; it ensures excellent signal quality
(signal-to-noise ratio), even in the most demanding situations.
