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 for the first time a complete video assist system
totally into the camera body. It offers unsurpassed image
quality combined with a state-of-the-art inserter to add
frame lines, time code and text to the video image.
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
5-150 fps because the video image is always taken at
the ideal position of the mirror shutter.
• 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 im-
portant image area.

General Description
8
• 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 output, 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.
• 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.
• 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.
• Indoor/Outdoor and automatic white balance
White balance can be set to indoor with 3200 K,
outdoor with 5600 K and automatic adjustment.
• Mini monitor connector
The IVS offers a connector for a 12 V LCD mini monitor.
Note: Both ARRIFLEX 435 versions (435 and 435 ES)
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 pic-
ture 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

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 ARRI-
FLEX 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 Mo-
dule 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.

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
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.
a) Remove the view finder system by loosening the three
mounting screws ➪ photo.
Support the viewfinder system.
Do not touch optic surfaces.
