5. Richer Images = More Storage
• Frame rates for movie content are
increasing from the historical 24
frames per second (fsp) to 48 or 60
fps and may eventually be as high as
300 fps
• Cameras are now available that can
support 200 fps (even up to 3,000 fps)
• 4K production is commonplace but 6K
and even 8K production starting in
professional video projects
• Video resolutions of 16K and even
higher are contemplated in the future
(higher res capture = future proofing)

6. New Views
• KDDI and some European
players have performed “free
viewpoint” demonstrations
with content captured using 4-
30 4K video cameras
• Light-field imaging could allow
even more immersive 2D and
3D video (greater image depth
possible, at least 3X more
storage
• This is in addition to
conventional high dynamic
range (HDR) images and
greater color depth

7. How Long Until Exabyte Video?
• A calculation shows that 16,000 X 8,000 pixel
resolution, 24 bits/pixel, 300 fps raw video
content could require 115 GB/s data rates and
414 TB/hour. If this was full stereoscopic
capture then these requirements would double.
If 4 cameras were used to create data for a “free
viewpoint” presentation, the raw data would be
1.66 PB for an hour of content
• Within 10 years we could have pro-video
projects generating close to an exabyte of data

8. Virtual Reality: Making A Holodeck
• Free floating
holographic and other
advanced display
technologies—within
the next 10 years we
could approach a
display allowing you to
move within the
action—leading to
holodeck-like
experiences

• 25.6% of 2014 Survey participants use cloud-based storage in their post
production (24.7% in 2013) and 28.1% of these had >1TB of cloud storage (23%
in 2013)
17. The Cloud for M&E Content
• In many regards cloud offerings are an out-
sourcing approach
• But there are new M&E capabilities enabled by
the rise of remote services
• Growth in cloud storage use by professional video
– Enables collaborative workflow
– Internet enabled content distribution with various acceleration
methods
– New cost effective services through the cloud enable greater
sophistication for smaller shops
– Some vendors offering cloud “archiving” services

18. Increasing Role of Flash Memory in
Media and Entertainment
• Flash is the most popular storage media for
professional cameras
• Flash is used for content delivery—as an
acceleration layer
• Flash memory is starting to be used for fast
play-out in post production
• Flash memory could eventually supply primary
storage in storage systems with HDDs as
secondary storage

19. 2014 storage architecture trends
• Growing applications with
solid state storage
– Content delivery and post-
production
– Combinations of flash and HDD
– Hot storage on flash and cold
storage on HDDs and tape today
– Cold storage on flash?
• Higher speed storage
interfaces find broader use
- Thunderbolt now at 20 Gbps)
- PCIe/SATA and SAS Express
- 12 Gb/s SAS
- USB 3.2 (10 Gbps)
-100/40/10 GbE & 16 Gb FC

20. The Future of Content Distribution
• MPEG H.265
encoding (up to a 50%
additional compression
beyond H.264)
– 2-3 X additional overhead
for decoding (HW products
in 2014)
– About 100 X more
processing overhead at the
source for the best quality
delivery content
• Adaptive Dynamic
Streaming over HTTP
(DASH): seamless
adaptive streaming of
content.

•In 2014 67.3% of the
respondents said that their annual
archive growth rate was >6% (this
was 65.3% in 2013).
•Tape and HDDs dominate long
term archival media
•Some backup to the cloud or
local network storage (increasing
trend)
•About 25.4% of survey
participants never update their
digital archives

Conclusions
• Enabled by lower cost storage and other infrastructure--
image resolution, complexity and frame rates are increasing,
driving storage demand for content workflows and archiving
• Cameras moving to flash memory for on-board storage
• Flash memory is driving the introduction of faster interfaces
enabling speedier video bandwidths and leading to a new
storage tiering and high performance interfaces
• Cloud storage starting to show up in various M&E
applications to help create collaborative workflows, content
delivery and archiving
• Active archives are changing the face of archiving to meet
huge archive storage demand
