Assimilate Scratch VR Z Tools and Z Cam S1 VR Camera Used to Live Stream 360º Cardiac Surgery to Doctors’ Conference in Hyderabad, India


SANTA CLARA, Calif.–(BUSINESS WIRE)–The Z CAM S1 VR Camera and Assimilate’s Scratch VR Z tools are adding
value to 360-degree medical and educational experiences. V3RA
Studios (
in Hyderabad, India is at the forefront of producing 360/VR experiences
for critical, real-world applications like cardiac surgery. They have
produced a 360/VR live-streaming broadcast of cardiac surgery to a
conference of cardiac surgeons at the Novotel conference center.

V3RA Studios has a clearly stated passion for creating 360/VR
videos because they capture the beauty and stories of the world. Company
co-founder Siddarth Kunwar spearheads the VR/360 productions and takes
on the roles of DP and director for many of the VR experiences.

Rapidly expanding their business, V3RA recently registered a
new company, Doctravsion, and teamed with Dr. Srinivas, Interventional
Cardiologist at the Citizens CATH Lab, as an advisor. In this capacity,
they developed a 360/VR project for Advanced Cardiovascular Solutions
India (
Fraternity of Advanced Cardiovascular Technique (FACTS) conference (

Dr. Srinivas and other top cardiovascular surgeons in India liked the
idea of implementing 360 for its larger canvas size and wanted to
broadcast 360 live from a cardiac surgery room to the Hyderabad
International Convention Centre (HICC) Novotel, where doctors were
showcasing and discussing their new techniques and practices at the
conference for FACTS.

The Times of India, August 21, 2017 reports, “The immediate
advantage of using 360 over a more traditional, two-dimensional
educational approach is that one gets the feel of being in the same room
as the operating doctors. Also, 360-degree content only requires a
single camera in the room, thus adding to the logistical advantages of
this method. Even machines used in surgical procedures can be zoomed in
on, to get a better view,” said Dr. Srinivas
, Interventional Cardiologist at the Citizens CATH Lab, who is
working in tandem with Doctravision, a company focusing on providing
immersive live-streaming solutions for medical conferences all over
South East Asia.”

The shoot, using the combination of one Z CAM S1 VR Camera and
ASSIMILATE’s SCRATCH VR Z software occurred in the CATH lab operating
room of three hospitals: NIMS Hyderabad, Apollo Hospital Secunderabad
and Citizen Hospitals Hyderabad. The live feed was sent to the ICC
convention hall at the Novotel Hotel, Hyderabad, via optical fiber
cable, where it was projected on to an 18’ x 16’ screen.

“During the shoot, we were able to focus on the work of the surgeons and
the support staff, showing the interdependency and importance of the
tasks that make such a surgery successful,” stated Siddarth Kunwar,
director and DP for this project. “By moving the camera, you can see the
effect of the metrics as well, such as the heartbeat monitor and blood
count, during different stages of the operation. The viewer can learn
from these advanced operating techniques and how top surgeons align
their staff and equipment to achieve optimal results during the

Kunwar noted, “By using one integrated solution of the Z CAM S1 and
SCRATCH VR Z, our equipment was not intrusive – about the size of a
large coffee mug on a monopod instead of a 2D camera sitting on a tripod
with an operator behind it. The surgeons considered this an added

Kunwar describes the live streaming as simple as shoot, click, present.
“We made a quick stitch through Kolor Autopano and used the .kava file
when prompted for the template in SCRATCH VR Z. We pressed the live
button, set the bit-rate to 35mbps and disabled save-content to disk.
From SCRATCH VR Z, we went straight to broadcast and screen at the
Novotel. At full-screen everyone could see a very clear, live view of
the surgery,” said Kunwar.

In the future for live streaming 360 projects, Kunwar is considering
stacking two S1 cameras so that one stream could be used for other
client purposes, such as streaming to another social media platform via
a different desktop or recording to a hard drive for future use.

Kunwar has found that if you have the right VR tools – camera, stitching
and post-production software – there’s not much deviation between a 2D
and VR workflow. Of course, the VR files are larger than 2D and require
a much higher level of computational power and storage but that can be
managed with some careful planning. “With advances in these types of
tools, and the many VR headsets that are increasing productivity and
making viewing comfortable, 360/VR experiences are clearly the future of
entertainment, education, and communications. We are geared up for it
with the right talent and the right tools.”
