VLK4 with rack remote control
FEATURES
VLK4 is a NTSC/PAL single RU/19"
device which enables insertion of 4 separate linear keys.
All VLK4's functions are operable
by a remote control.
VLK4 is the solution to all
problems caused by the insertion of titles on video images.
As you know, a "hard key" titling
often determines a confusion between the signals and causes the well known
"sparkling edges" effect.
Our equipment, on the other hand,
thanks to its linear key transparent titling, provides the best sharpness
of the video edges and an extreme transparency of the incoming video signal.
This enables a multi-layer titling
(BACKGROUND, MID-BACK, MID-FORE and FOREGROUND etc.).
The linearity of the titling, is
made possible by a signal of control KEY which determines the mixing level
of main picture (BACKGROUND) and titling signal (FOREGROUND).
Desk remote control
VIDEO MIXERS
Many video mixers do not allow the
linear insertion because their performances are limited to the "hard Key"
type.
The VLK4 can be added up to your
mixer to update the keyer system.
Furthermore, VLK4 has KEY and FILL
outputs which, if connected to the video mixer's KEY input, provide to
the latter all the engaged keys just by using the KEY control on the mixer.
Rack remote control (1/2 1RU)
APPLICATIONS
Thanks to its features, VLK4 can
be employed for various applicatons.
The sector of graphical images is
surely the one where you can get better results by using a linear key transparent
insertion.
For example it provides fade or
curtain effects between BACKGROUND and FOREGROUND or the insertion of an
animation on live images.
