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.
