SANTA MONICA, CALIF.—In one l-o-n-g
drop on Oct. 14, Austrian daredevil Felix
Baumgartner proved that a man in a spacesuit
could fall safely back to Earth from
more than 24 miles high. He also proved
that it’s possible to get outstanding video of
the event and broadcast it live to millions on
the Internet.
Baumgartner floated to the edge of space
in Stratos, a pressurized capsule hung from
a balloon. At a height of 128,100 feet, he
stepped away from the capsule, fell freely
for nearly 23 miles (including breaking the
sound barrier), then drifted to ground on a
parachute.
The event was captured by cameras
stuffed into the capsule and by groundbased
cameras with massive lenses, and
relayed live to YouTube for a worldwide audience of 52 million. The primary sponsor
for Baumgartner’s space jump was beverage
maker Red Bull, and its media group—
Red Bull Media House—pulled together all
the cameras and necessary communications
equipment.
“We knew that the technology existed to
document the project,” said Charlie Rosene,
executive producer for Red Bull Media
House North America, in Santa Monica, Calif.
“But how do you combine established,
military-grade tools with state-of-the-art
high-definition digital broadcast equipment
so the world could experience this project
from an intimate front-row seat?”
Red Bull Media House decided to broadcast
the jump live on YouTube.
“We have partnered with YouTube for
several years, and have worked closely
with them in developing our digital channel
that includes exclusive programming,”
Rosene said. “YouTube also gave us a truly
global exclusive digital streaming platform,
as our goals were to touch not only the
U.S., but a worldwide audience.”
But YouTube? How many people would
stop to watch something like this on You-
Tube?
“Just like Felix, we set a few records of
our own, including more than eight million
concurrent live streams on YouTube and
52 million views during our live presentation,”
Rosene said. “Safe to say, we would do
it again.”
The jump was also broadcast live on
Discovery Channel, where it became the
highest-rated non-prime television event
in the network’s history.
‘OB TRUCK IN A CAN’
The Red Bull Stratos capsule was fitted
with nine HD video cameras, three Canon
still-image cameras and three RED 4K cameras,
although one of the RED cameras was
set to shoot 120 fps at 2K resolution. In addition
to all that gear, there were five HD
cameras on Baumgartner’s suit, all of which
were record-only and did not provide live
images.
Putting the camera systems together
was the job of Jay Nemeth, Red
Bull Stratos’ director of photography.
He pointed out that
there’s more to getting images
from the edge of space than
simply mounting a few cameras.

The JLAIR Long Range Optical Tracking System contained highpower telescopes with an HD camera and a RED Epic camera running at 4K 120 fps. A shortwave infrared camera captured Baumgartner as he stepped off the capsule 30 miles away. |
“The electronics cage in our
keg-sized housing contained
nine HD P2 recorders, a router,
nine camera control units,
downconverters, audio embedders,
SDI crossconverters,
48 channels of GPIO control,
telemetry computer, mic preamps,
DC regulators, 60 spacerated
circuit breakers, telemetry
RX/TX radios, video transmitters
with power amplifi ers, and several
other items,” Nemeth said. “We called it
the ‘OB truck in a can’.”
There were many technical concerns
for the video gear.
“There wasn’t much that could be used
off-the-shelf without some sort of modification,”
Nemeth said. “The near-space conditions
created problems with extreme cold,
down to –95 degrees at one point and high
temp conditions at the same time that required
us to design and build cooling systems
with complex heat exchangers. The
REDs generate so much heat that we designed
nitrogen-filled housings to give the
fans a dry convective medium to circulate.”
Nemeth said that the HD video cameras
used in the Stratos capsule were proprietary
space-rated units that are not made by
a manufacturer familiar to the video community.
The camera system design was finalized
in 2009, which meant that the project
couldn’t take advantage of newer products
and developments.
“I would have loved to use the RED
Epic on the capsule, but when we were
constructing the housings and putting
the control system together in early 2009,
they weren’t available,” Nemeth said. “It
just wasn’t possible to start the design
and integration process over.”
MICROWAVE TELEMETRY
Riedel Communications provided three
microwave transmitters in the Stratos
capsule, as well as telemetry radios and
receive equipment. Red Bull Media had
one receive site at mission control in New
Mexico, and another one downrange fitted
with a FlightLine JLAIR long-range optical
tracking system.
The signals received downrange were
relayed back to mission control using 2
GHz and 18GHz terrestrial links provided
by 3G wireless. Although the production
team considered downlinking live
video from Baumgartner in freefall, it was
deemed a safety hazard by the science
team, so the five cameras on Baumgartner’s
suit were record-only.
Riedel has worked with Red Bull Media
on a variety of projects, such as the Red
Bull Air Race, so the company was a part of
the space jump project right from the beginning.
Still, Riedel’s experience had been
all within the comforting envelope of the
atmosphere, and providing live communications
from 24 miles up would be… well,
outside the envelope.
“There were number of challenges that
were new to us,” said Thomas Riedel, president
of Riedel Communications in Wuppertal,
Germany. “Ranging from color correction
and white balance challenges for
the cameras due to the change of the atmosphere,
to tracking and telemetry tasks
that were more demanding than usual.
Together with a group of specialists in the
Red Bull Stratos team and our own R&D
team, we managed to overcome them.”
If you’re interested in using a piece of
historically significant equipment, you
might be surprised to learn that it’s available
for rent.
“Besides being a manufacturer, Riedel
also runs a large-scale rental business supplying
equipment to events and productions
such as the Olympics and FIFA World Cups,”
Riedel said. “The equipment used at Stratos
will be part of our rental stock—a good measure
of equipment already was part of our
rental stock when we started working with
Red Bull on the Stratos project, such as Artist
digital matrix intercom systems and Medior-
Net fiber backbone technology for distributing
HD video/audio signals.”
Riedel said that there was much learned
during the Red Bull Stratos project and
that the experience was of “high value.”
However, there are no immediate plans to
create new products as a result of Riedel’s
experience on the space jump.
LIVE GRAPHICS
Live graphics for Baumgartner’s leap
were provided by Vizrt, which supported
the project with three Viz Engines, four Viz
Trios and a Viz Graphic Hub.
“The biggest challenge was to gather all
the data sources from all different ‘providers’
[capsule telemetry, Felix bio-meds, mission clocks, chest pack informations, and
simulation data calculated in cooperation
with the Technical University of Munich],
and to deliver them to the world outside
of the command center in Roswell, N.M.,”
said Petter Ole Jakobsen, CTO for Vizrt.
Jakobsen pointed out that only standard
off-the-shelf Vizrt gear was used for
the project.
“The Viz Graphics Hub shared memory
maps workflow was a breakthrough,
allowing a normal Viz Trio studio workflow
synchronized between the U.S. and
Europe,” he said. “So even in a remote
studio, the Viz Trio operator was accessing
live data through normal page recalling—
no third-party software needed to
be installed.”
Scott Gillies, director of production
and technology for Red Bull Media House
North America, was responsible for the
technical side of the television production
for the space jump. As important as
the video feed was, the primary concerns
of the entire team were safety and situational
awareness.
“We needed a system that would let us
see the pilot, flight-train connections, and
the balloon in real time during the flight,”
Gillies said. “Secondly, we needed to see
Felix during the descent. These were no
small challenges, especially when there
are tight timelines and multiple teams
working together.”
So how do you create a production
system for such an extreme event?
“The goal for the Red Bull Media
House was to deliver the very best images
possible given the constraints of
physical space, heating/cooling and power
consumption,” Gillies said. “If we could
utilize existing technology that was robust
enough, then we were pleased, but
at the same time we wanted to push the
envelope wherever possible.”
Despite pundits who decry today’s
media landscape as fractured and fit only
for those with attention spans measured
in seconds, attracting 52 million views to
a live nine-minute video is a significant
accomplishment. Gillies points out that
viewers didn’t tune in to see the gear.
“To make compelling content, the story
and technology have to go hand and
hand—one cannot outshine the other,”
he said.
If you missed the live broadcast, there
is a re-cap on YouTube and plenty of other
videos available, including a documentary
co-produced by BBC and National
Geographic. That documentary was
shown on National Geographic on Nov.
11, and included previously unseen video
from one of the cameras on Baumgartner
during the jump.
