BBright: Full UHD HEVC Workflow
from Contribution to Delivery
Despite the inception of some very new video codecs, such as
AV1 for the OTT arena and AVS 2.0 for China, the HEVC/H.265
codec has now become ubiquitous worldwide...

EVC coding refinements indeed bring
around 50 per cent bitrate, whether for
broadcast, IPTV, cable TV or OTT. Today, all
4K - UHD channels use the HEVC technology
for final delivery to end-consumers (to STB or
TV, or on mobile).
At live production level, and within
broadcaster's head-ends, HEVC is rather
common too, although some older video
compression codecs remain in use. Live
sport contributions would often be processed
based on very high bitrate JPEG-2000

BBright is a reputed specialist of
Ultra HD/HEVC/HDR workflows.

BBright delivers solutions for high bitrate

The companion BBright playout servers can
directly accept HEVC Transport Stream files
either for baseband playout (quad 3G-SDI
output) with graphical insertions, or for final
delivery to end-consumers (with multiple
channels on TSoIP output). The scheduling of
playout events is embedded and sequenced
internally and does not require costly external
automation control systems.
All BBright products are SDR, HDR10-PQ
and HLG compatible with more support for
other HDR schemes to come. Such products
are already deployed in North America, Latin
America and Europe to support the football
World Cup.
BBright is ready to team up with Asian
broadcasters and service providers to deploy
full HEVC workflows to improve video quality,
reduce bandwidth and storage requirements
and ultimately minimise CAPEX and OPEX for
new 4K/Ultra HD Services.
BBright is exhibiting at booth 4F1-04.

Sci-Fi Short Hyperlight Delivered in
HDR with Blackmagic Design
Blackmagic Design's range of digital film cameras (Stand: 6S2-01/3), including the URSA Mini 4.6K and
URSA Mini Pro, have been used in the filming of Hyperlight...

yperlight is a science fiction thriller from
writer and director Nguyen Anh Nguyen
(Akira Project and Temple).
Post-production for the movie was
completed in DaVinci Resolve Studio,
including the edit and grade, while the visual
effects were completed in Fusion Studio
and overseen by VFX supervisor Santiago
Menghini.

Confined space
According to DP Simran Dewan, the URSA
Mini's compact form factor and ergonomics
made it the ideal choice for Hyperlight as the
majority of the film takes place within the
confines of a spaceship. "Being lightweight
and easy to use, the URSA Mini allowed us
to readily switch between a variety of different
setups on a quick release plate," he said. "Not
only that, we could manoeuvre into the tight
corners of the set to create unique angles."
Dewan pushed to shoot in CinemaDNG

RAW as his preferred workflow. "You end up
with a much thicker digital negative with more
latitude and information for post-production.
Treating the camera as I would any other film
stock, I rated it at 800 ISO but metered for
500 and paired it with a set of vintage Kowa
anamorphic lenses. I've always imagined
film in this format, and the lens perfectly
complemented the colour fidelity of the 4.6K
sensor."
The URSA Mini was rigged for a Chapman
Hybrid dolly and a Ronford-Baker Atlas tripod

Naomi Silver-Vézina relied on
management tools such as flags and
markers to help identify proxy clips,
previz shots, mockups and final shots.
Resolve's burn-in text functionality
and titling tools were also used to add
precise notes to any placeholders: a
crucial aspect to such a VFX heavy
project.
