General Description of the ARRICAM ST HD -IVS
The Integrated HD Video-Assist System (HD-IVS) for the ARRICAM ST is a
breakthrough product, which uses innovative digital technology to create
high definition video assist images for the ARRICAM ST film cameras. Wide
dynamic range, excellent color reproduction and low noise are combined
with ARRI’s unique Ground Glass Cancellation (GGC) technology to create
beautiful, high resolution preview images. The HD-IVS provides a superior
image for the director and cinematographer on the set, allowing them to
judge each take while shooting on 35mm film.
Main Features
•
High resolution
Because of a sensor with 1920 x 1080 pixels, the resolution is
dramatically increased resulting in an unprecedented image quality.
•
3 Stops more dynamic range than standard IVS
The HD-IVS works internally with 12 bit pixel depth and only for the
output it is re-sampled down to 10 bit. This creates a higher dynamic
resulting in more details in shadow areas.
•
Anamorphic de-squeeze
To de-squeeze anamorphic images, the HD-IVS comes with software
options for a de-squeeze factor of 2 and 1.3.
•
Screen capture
Individual still images can be stored on a standard USB stick in a
standard bitmap format.
•
Ground Glass Cancellation(GGC) for a clean image
The structure of the ground glass in the optical system can be
recognized, stored, and electronically subtracted from the actual image.
Therefore the image does not show the ground glass structure any
more.
•
Less noise through optimized exposure control
Because of a motorized iris in the HD video assist the IVS lens is always
controlled so that a maximum amount of light reaches the video assist
sensor. Thus less electronic gain is needed and the noise is reduced.
•
Excellent color reproduction
A state-of-the-art bayer mask on the sensor and a high sophisticated
color processing electronic ensure an excellent color reproduction.
•
Flicker-free
An integrated digital frame store enables the video camera to be
synchronized to the film camera's mirror shutter and provides (in
