16 LDX 86 High Frame Rate/HD/3G/4K Camera Platform User’s Guide (v2.0)
Chapter 1 - Introduction
1.2 Technology
1.2.1 LDX 86 Worldcam
The LDX 86 Series is designed for flexibility, with the ability to be used for both dramatic
productions and live broadcasts, especially sports. The use of compact 2/3-inch lenses with a
B4 mount gives you the large zoom range, speed and depth of field which is required for
demanding live and many dramatic productions.
Offers all HD/PsF/3G production formats plus an upgrade path via GV-eLicenses to 4K (LDX 86
4K) as well as to 6X HD, 3X HD and 3X 3G high-speed (LDX 86 Universe).
1.2.2 LDX 86 HiSpeed/XtremeSpeed
The LDX HiSpeed is the newest generation camera for 3X speed applications with improved
performance.
The LDX XtremeSpeed camera system sets a new standard for ultra slow-motion (6X) image
acquisition by introducing a workflow with instant time-to-air without a cumbersome double-
action memory buffer in the camera—so that not a single moment of the action will be missed
or lost.
Both high frame rate cameras versions offer the highest sensitivity and image performance
across all acquisition speeds while the unique AnyLightXtreme
TM
flicker reduction assures that
no more irritating light flickering occurs in the replays.
Fully integrates with Grass Valley K2 Dyno Replay Systems and includes K2 Dyno AnySpeed
TM
technology which provides for smooth playback at any speed from 0% to 200%, dramatically
expanding the ability to tell a compelling story during replays.
AnyLightXtreme™ flicker reduction system
All camera operations with high frame rate capturing—such as in super slow-motion and ultra
slow-motion applications—face a unique challenge caused by most artificial light sources. In
stadiums, sports arenas, and the like, lighting conditions are often not ideal for highspeed
acquisition. A visual flicker is perceived as changes in light levels due to the mismatch between
the camera scanning frequency and the power frequency of artificial lights.
With the unique AnyLightXtreme feature for the LDX 86 HiSpeed and XtremeSpeed cameras,
there is compensation for this mismatch that helps to automatically reduce flicker, with several
presets for different lighting conditions available in the cameras. The various presets permit the
camera to reduce the flickering in the most effective way based on the lighting situation and
scanning frequency.
1.2.3 LDX 86 4K
The 4K version LDX 86 Series offers the new standard in live 4K (3840x2160p50/59.94)
acquistion. Unlike other 4K cameras, what looks like “in focus” in the viewfinder actually is “in
focus” in Grass Valley 4K cameras. As was learned in the transition from SD to HD, keeping
focus in higher resolutions on a small viewfinder can be challenging for operators. Grass Valley
has put significant effort to make sure that operators can focus in 4K quickly and accurately.
The 4K version also supports a wide variety of traditional 3G and HD acquisition formats, so
that you can use the LDX 4K for traditional sports, dramatic productions, news, documentaries
and theatrical acquisition.
