With the new IVS-colour video assist for the ARRIFLEX 535B, video of the highest image quality is now available for the entire range of ARRIFLEX cameras. As with the ARRIFLEX 435, the video assist has also become an integral part of the 535B and 16 SR3 cameras. The technical possibilities such as inserting of image format frames, camera status indicator, Time-Code, userbits, text etc. were also incorporated.

The number of cables has been reduced to a minimum: just one cable from the camera to the power supply and the usual connector to the recorder or monitor are necessary.

| High speed – high resolution –
flicker-free
Extremely fast optics and a highly sensitive CCD-chip ensure an excellent colour video assist image in editing quality, even in difficult lighting conditions. The effective sensitivity corresponds to 4000 ASA. Even with the most sensitive film stocks, sufficient reserves are available. The high resolution image quality, which surpasses that of any add-on system, was achieved by specifically designed optics, each an integral part of the camera’s viewfinder system. Through the digital image storage, the video camera can be synchronised to the running speed of the film camera. From 5 fps on the system is completely flicker-free. The exact moment of the exposure of the CCD-chip is then chosen to optimally match the mirror shutter position of the camera. As well as the usual composite output, the IVS offers a Y/C interface for better resolution without disturbing composite colour artefacts. Inserting format masks, camera status indicator, Time-Code and text
Additionally the IVS offers a particular user comfort: format markings can be electronically inserted into the video image and therefore remain clearly visible even in low lighting conditions. The area outside the format marking can be darkened electronically to better emphasise the image area. In the same way Time-Code and camera status indicators such as "Standby/Run" can be directly inserted into the video image. This ensures a quick interface to off-line video editing systems. An explicit correction is assured even for NTSC video assist through a display of the "3:2-Pulldown". The Time-Code information is of course available as text as well as VITC. In addition a serial interface offers the possibility of inserting text such as scene and take numbers into the video image. On-Screen User Comfort
A compare function allows an image to be saved and then to be compared
with other video images. That considerably simplifies the setting up
of stop-motion images for example. The brightness of the video beamsplitter is automatically regulated
to the optimal range, however it can also be set manually. For the white
balance, two standard values for 3200 K and 5600 K as well as an automatic
balance are available. Via an external sync input the video camera can
be synchronised to an external video signal, facilitating the parallel
and trouble-free use of several cameras. For highest image quality, two separate optical configurations are
available for each camera: Academy and Silent for the 535B, Super and
Normal 16 for the 16 SR3. Each is optimized to utilize the entire area
of the CCD and, unlike zoom lenses, provides the best possible quality
and speed for the specific format. The optics are easily interchangeable
via a bayonet mount.
