Crystal Cathedral shines
with an all-new HD
infrastructure
Robert Schuller’s “Hour of Power” is
produced at the Crystal Cathedral,
a TV studio for televised congregational
Christian worship. Recently,
the program enlisted systems integrator TV
Magic to design and install a new HD production
infrastructure for the Crystal Cathedral.
Five Grass Valley LDK4000 1080i HD cameras
and various switching sources record
through seven Avid HD Adrenaline nonlinear
editing systems to a Unity centralized storage
system. This allows staff to take advantage of
Avid’s multicam editing features, with editing
of program content beginning immediately
following each Sunday service. Due to the live
nature of the program, one challenge was to
place all seven Avid systems into record mode
simultaneously.
TV Magic worked as a technical liaison
with Avid and other manufacturers to integrate
the facility’s new production gear in an
effi cient workfl ow. The systems integrator
also installed a Grass Valley Kayak HD two
M/E digital production switcher. One M/E
is used with an auxiliary panel to provide
switching and keyed graphics for presentation
and image magnifi cation on the Cathedral’s
Jumbotron.
Within the control room, an Evertz MVP
multi-image display and monitoring processor
feeds four Panasonic HD plasma displays,
allowing production personnel to monitor
all switcher sources, previews, programs and
Jumbotron feeds. The system supports display
of up to nine cameras.
Today, production staff shoot the live service
and send all camera feeds, ISO feeds and
the director’s cut to the Avid system just 10
minutes after the service. The seven Avid systems
capture all video, and on Monday, they
serve as individual edit bays for work on different
pieces of the show.
The Avid systems feed two virtual edit bays,
one equipped with Digidesign’s Pro Tools HD
for sweetened audio layback. The other Avid
systems ingest archived material from tape
and output rough-cut versions of the program
for audio sweetening and approvals.
All of the Avid systems are situated in the
machine room located in a different building;
editors use an Avocent KVM switching system
to work on these systems remotely.
Live audio is captured directly into a Pro
Tools HD multitrack session. A mixed-down
version is provided to the remote Avid systems.
Edited versions are provided back to audio
for sweetening. Once audio is completed,
it is laid back directly into the timeline using
drag-and-drop functionality.
The HD upgrade allows the “Hour of
Power” production team to deliver a muchimproved
SD signal to broadcasters and highquality
programming to the growing number
of TV stations making the leap to HD. |
