2 Safety Specifications

Warnings

Note: Operational error possible!

Danger of injury

or equipment damage possible!

General Safety Specifications

Attention! Danger of injury!

Never place your hand in the lens mount

receptacle or the inside of the camera or

magazine while it is running.

The control panel of the IVS must not be operated

using hard ord sharp-edged tools, e.g. screw-

drivers.

• In order to ensure optimal performance, it is essential

that you acquaint yourself with this instruction manual,

and the manual of the ARRIFLEX 535B.

• Use the IVS 535B only with ARRIFLEX 535B cameras,

and only as described in this manual!

• Assembly and initial operation should only be carried

out by persons who are familiar with the equipment!

• The video lens must be properly inserted into the CCD

optic module, as incomplete insertion might result in

damage to the beam splitter when attaching the unit to

the camera body!

• Remove all cables before transport or servicing!

• Repairs should be carried out only by authorized

service centers!

• Use only original ARRI replacement parts and accessories!

• Check all operations on the corresponding monitor!

Safety Specifications

Important Notes

• In wet weather safety precautions for handling electrical

equipment should be taken.

• Avoid operational errors!

• Do not touch optical surfaces!

• Clean optical surfaces only with a lens brush or a clean

lens cloth! In cases of solid dirt moisten a lens cloth

with pure alcohol.

• Do not use solvents to clean

• Do not use force!

• Do not remove any screws which are secured with paint!

Product Specifications

In the case of inquiries or when ordering parts, please

advise serial number and model.

• Always send the CCD optic module together with the

inserter/antiflicker module in case of any service jobs.

3 General Description of the IVS

The Integrated Video-Assist System (IVS) for the ARRIFLEX

535B ergonomically integrates with a minimum of external

cabling a complete video assist system into the camera body.

It offers unsurpassed image quality combined with a state-of-

the-art inserter to add frame lines, time code, camera status

and text into the video image.

3.1 Main Features

• Integrated into the camera body:

Instead of a bulky add on, the video assist is an integral

part of the camera.

• High sensitivity:

A high speed lens with an aperture of 1: 1.4 and one of

the most sensitive CCD-chips available on the market

provide an excellent color video image in editing quality

even when the light is set for high speed film stock to

be pushed during processing.

• High resolution:

The design of the new IVS optics was based on the

535B’s viewfinder data and resulted in an image quality

which can not be attained 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

5-60 fps. The recording of the video image is synchro-

nized with 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

low contrast conditions. The area outside the frame

lines can be darkened electronically to emphasize the

important image area.

• Integrated IVS film counter:

In addition to the camera speed an independent IVS film

counter can be inserted into the camera status line to

support material logging.

General Description

• 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 names

can be added to the video image by sending characters

via a serial interface.

• 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, such as gain control, can be conveniently pro-

grammed with an onscreen 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 multiple 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: If neither time code is used nor data is sent via

the serial interface, it is possible to work without

the data cable ZV4.

Note: 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.

General Description

3.2 System Components

The IVS consists of:

• Optic Silent and/or ............................ (K2.47298.0)

• Optic Academy ................................. (K2.47301.0)

• Video Electronic complete ......... (K2.47306.0 for PAL

or K2.47307.0 for NTSC)

The complete video electronic consists of four parts:

• CCD Optic Module

• Inserter/Antiflicker module

• RS cable............................................ (K4.47733.0)

• Data cable ZV4 ................................. (K4.47730.0)

Accessories for the IVS are:

• Software for text input ............................ On request

(for Macintosh / Windows)

3.2.1 Optic Silent

For a complete and working IVS, either the optic silent or

the optic academy has to be installed inside the CCD optic

module. These are easily interchangeable.

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. To check for important objects outside the image

recorded on film there is an additional area around the

format markings.

The lenses are especially designed and built for use with the

ARRIFLEX 535B to achieve the best image quality possible.

The aperture of 1:1.4 is particularly important for use as

video assist lenses: only a small portion of the light that passes

through the camera lens goes to the video chip. The lenses

are not designed as zoom lenses because it would be im-

possible to get the same image quality and speed.

All silent optics are marked with an S in the serial number,

e.g. S0040.

There is no difference between lenses for PAL and NTSC.

General Description

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 are easily interchangeable.

The optic academy forms an image on the CCD chip based

on the 35mm academy format with a picture width of 22mm.

To check for important objects outside the image recorded

on film there is an additional area around the format markings.

The lenses are especially designed and built for the use with

the ARRIFLEX 535B to achieve the best image quality possible.

The aperture of 1:1.4 is particularly important for use as

video assist lenses: only a small portion of the light passes

goes through the camera lens goes to the video chip. 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 is no difference between lenses for PAL and NTSC.

3.2.3 CCD Optic Module

The CCD optic module, which is mounted on the ARRI-

FLEX 535B’s viewfinder 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 focus. It also houses a

video pre-amplifier to increase the sensitivity of the IVS at

low light conditions.

The CCD optic module is available in two versions for PAL

or NTSC.

Note: It is necessary to keep the combination of CCD

optic module and inserter/antiflicker module

together as delivered. Mixing the modules might

lead to reduced image quality.
