3.2 Installing the HD-IVS Lens
The HD IVS allows the use of two different IVS prime lenses as a video
assist lens. The 4:3 IVS lens is optimized for taller aspect ratios such as 4:3
or anamorphic formats. The full 4:3 ground glass image will be displayed
on 1440 x 1080 pixels on the HD monitor, leaving black vertical bars to
the left and right of the image (“pillar box”). These black bars optionally
display metadata or the OSD menu.
The 16:9 IVS lens is optimized for aspect ratios of 16:9 or wider. A 16:9
aspect ratio image from the ground glass will be displayed on the full HD
monitor in 1920 x 1080 pixels.
Note: If a 4:3 IVS lens is installed together with a 16:9 ground glass, black
areas will appear not only left and right but also top and bottom of
the monitor screen. The usable image on the monitor will be too
small. Vice versa, if a 16:9 IVS lens is installed together with a 4:3
ground glass, the image will be cropped on top and bottom. Both
situations are not recommendable. Please use an appropriate
combination of ground glass and IVS lens.
This operation should be carried out only by an experienced
technician.
Use appropriate care to avoid electro static discharge.
Do not touch optical surfaces and do not use force.
If you feel uncomfortable in changing the IVS Lens, please don’t
hesitate to consult one of the authorized ARRI Service Centers.
