3. General Description of the IVS
The Integrated Video-Assist System (IVS) for the ARRIFLEX
435 responds to a strong request from camera users and
integrates a complete video assist system totally into the
camera body. It offers unsurpassed image quality com-
bined with a state-of-the-art inserter to add frame lines,
time code and text to the video image. Colors can be set
to fixed values or controlled manually or automatically.
3.1 Main Features
•Integrated into the camera body
Instead of a bulky add on, the video assist becomes an
integrated part of the camera without additional cabling.
•High sensitivity
A high speed lens with an aperture of 1 : 1.4 and one
of the most sensitive CCD-Chip available on the market
provide an excellent color video image in editing quality
even when the light was set for a high speed film stock,
which will be pushed during processing.
•High resolution
The design of the new IVS optics was based on the
435´s view finder data and resulted in an image quality
which can not be realized by add on solutions.
• Flicker-free
An integrated digital frame store enables the video
camera to be synchronized to the film camera´s mirror
shutter and provides a flicker-free video image from 1 fps
to maximum speed (in manual gain control mode)
because the video image is always taken at the ideal
position of the mirror shutter.
Flicker free can be switched off to bypass the digital frame
store and have the video assist output with no delay.
•Full manual white balance
In addition to the standard indoor white balance setting
with 3200 K, an outdoor setting with 5600 K and
automatic adjustment, color can be fine tuned with a
separate red and a separate blue channel for manual
white balance.

•Even further resolution in camera run mode
Video images are now also in the camera run mode in
almost full video resolution due to a new technology.
•New video exposure time mode ‘identical with film exposure’
The exposure time of the video assist can be programmed
to follow the exposure time of the film. Thus, identical
motion blur on film and video assist is achieved.
•Store and recall for all settings
All settings can be stored and recalled. By this, it is possible
for example to trim all the settings for indoor shooting,
store them, have some exterior scenes, go back indoor
and call the old settings back.
Up to 6 sets of settings can be stored.
•Integrated frame line inserter
Frame lines can be electronically added to the video image.
This ensures that the lines are visible even in difficult
conditions. The area outside of the frame lines can be
darkened electronically to emphasize the important
image area.
•Integrated time code inserter
It is possible to insert Time code into the video image.
Thus, the video assist creates a reliable link to video
editing. The information on ”3:2” pull-down, which
can be inserted as well, ensures the same reliability in
an NTSC environment.
•Integrated text inserter
Additional text like take numbers or production name
can be added to the video image by sending characters
on a serial interface.
•Two additional Y/C Outputs
In addition to the usual composite outputs, the IVS offers
a Y/C output (S-VHS) for an even better video image
without annoying color artifacts with or without data
inserted into the video image. The output is on a standard
S-VHS connector as well as on two BNC sockets.
•On-Screen programming
All functions, which do not effect the image appearance
directly like gain control, can be conveniently programmed
with an onscreen programming menu on the video monitor.
• Full remote controllable
All settings can be controlled directly on the IVS as
well as via RS 232 with the remote control software
(under development)
•Image compare function
It is possible to store a particular image and compare

it against other images. This clearly shows the difference
between the images e.g. during stop effect shots.
•Automatic and manual gain control
The gain is controlled automatically to its best value
but can also be set manually.
•External synchronization input (Genlock)
The IVS has an external synchronization input to enable
multi camera use.
•Mini monitor connector
The IVS offers a connector for a 12 V LCD mini
monitor combined with a 1.1 A power supply.
Note: All ARRIFLEX 435 versions (435, 435 ES and
Advanced) can be equipped with the IVS
independently of the expanded function module.
However, the time code functions such as insertion
of time code, user bits, pull-down information,
VITC and white line flags can only be activated
if the expanded function module is installed.
As the IVS is designed for an 80 : 20 beam splitter, there
is no need for the 50 : 50 beam splitter, which is used for
other color video assists.

3.2.1 Optic Silent
For a complete and working IVS, either the optic silent or
the optic acacemy has to be installed inside the CCD optic
module. They can be easily exchanged.
The optic silent forms an image on the CCD chip which is
based on the 35 mm silent format with a picture width of
24 mm. An additional area will surround the actual image.
This is to check for important objects outside the image area.
The lenses are especially designed and built for the use with
the ARRIFLEX 435 to achieve the best possible image quality.
Especially the aperture of 1 : 1.4 is important for the use
as video assist lenses because only a small portion of the
light that goes through the camera lens reaches the video
chip. Therefore the lenses are not designed as zoom lenses
because it would be impossible to get the same image
quality and speed.
All silent optics are marked with an S in the serial number,
e.g. S0040.
There are no different lenses for PAL and NTSC.
3.2.2 Optic Academy
For a complete and working IVS, either the optic silent or
the optic acacemy has to be installed inside the CCD optic
module. They can be easily exchanged.
The optic academy forms an image on the CCD chip which
is based on the 35 mm academy format with a picture width
of 22 mm. An additional area will surround the actual image.
This is to check for important objects outside the image area.
The lenses are especially designed and built for the use with
the ARRIFLEX 435 to achieve the best possible image quality.
Especially the aperture of 1 : 1.4 is important for the use
as video assist lenses because only a small portion of the
light that goes through the camera lens reaches the video
chip. Therefore the lenses are not designed as zoom
lenses because it would be impossible to get the same
image quality and speed.
All academy optics are marked with an N in the serial number,
e.g. N0040.
There are no different lenses for PAL and NTSC.

3.2.3 CCD Optic Module
The CCD optic module, which is mounted on the ARRIFLEX 435
view finder system has to be equipped with a video lens.
This module contains the CCD-chip and all the necessary
elements to center the video image on the TV-Monitor screen
and to adjust the focus. It houses also a video pre-amplifier
to increase the sensitivity of the IVS at low light conditions.
The CCD optic module is available in PAL and NTSC.
It is necessary to keep the combination of CCD optic module
and Inserter/Antiflicker module together as delivered.
Mixing the modules might lead to a reduced image quality.
On request ARRI can supply a second CCD optic module
optimized for a particular Inserter/Antiflicker Module.
3.2.4 Inserter / Antiflicker Module
The Inserter/Antiflicker module contains most of the IVS
electronics. This 22 mm wide module, which is mounted on
the right side of the ARRIFLEX 435, holds the video camera
electronic, an anti flicker processor and the entire inserter.
All control elements, which are often used, as well as all
in- and outputs are located here.
The Inserter/Antiflicker module is available in PAL and NTSC.
It is necessary to keep the combination of CCD optic module

4.2 Mounting the IVS
The following tools are needed to mount the IVS:
3 mm allen key
0.5 x 3.5 mm screw driver (first time installation only)
2.5 mm allen key
1.5 mm allen key
As there is a vertical connector between the CCD optic
module and the Inserter/Antiflicker Module, it is necessary
to take the view finder system off the ARRIFLEX 435
before the IVS is installed.
The CCD optic module is mounted on the right side of the
ARRIFLEX 435 view finder system:
Disconnect camera of all power supplies.
For the initial installation of the IVS on the ARRIFLEX 435 it
may be necessary to exchange the flange, which is mounted
on the view finder system of the ARRIFLEX 435. The IVS is
delivered with a modified flange that can hold the IVS as
well as other video-assists. This new flange remains on
the ARRIFLEX 435. Therefore it is not necessary to remove
it when the IVS is taken off.
Support the viewfinder system.
Do not touch optic surfaces.
a) Remove the view finder system by loosening the three
mounting screws §.
