Among over 100 new editing
functions in the software markers
with on-screen annotations, subtitle
and closed captioning tools, and IMF
support.
Colourists can play with a new HD to
8K up-scaling feature in Resolve plus
expanded HDR support with Dolby
Vision and native HDR 10+ grading
controls.
The Studio version adds multi-user
collaboration, support for frame rates
over 60p, VR, more filters and effects.
With
productions
increasingly
requiring the use of surround or multichannel spatial reproduction, a new
ambisonic mic is made available from
RØDE. The SoundField NT-SF1 device
features four heads which records
separate signals (the 'A-format')
output over an XLR cable attached
to the bottom of the handle. The
A-Format is not intended to be used
without further processing and is
normally transformed into the second
set of audio signals, the B-Format
for manipulation offline. These are
accessing via a free plug-in compatible
with leading audio editors like Pro
Tools and Reaper. According to RØDE
it delivers "broadcast grade" signals
with very low noise, and
includes a windshield,
cable and shock mount
holder.
In
2007,
Apple
introduced the Apple
ProRes codec, providing
real-time,
multistream
editing performance and
reduced storage rates
for 4:2:2 and 4:4:4:4

Atomos Sumo 19inch and Shogun Inferno recorder/
monitors and drone and gimbals from
DJI are among the first devices to take
advantage of the format.
DJI debuted two advanced gimbal
controls for high-end cinematography;
the Master Wheels and Force Pro are
designed to offer precision control of
complex shots and/or fast moving
ones using DJI's own Ronin 2 and
the upcoming Ronin-S gimbals.
AI & Metadata
Artificial Intelligence, big data,
IoT and Cloud computing are
combining to offer the potential
for a step-change in efficiency
in what some are calling the
fourth
industrial
revolution.
The trajectory of video production is
theorised to move from the current
programme-centric to a storycentric process, where content is
automatically produced, targeted and
distributed to the viewer.
Not as far-fetched as it sounds,
the first stages of this are already
happening in news and sports
production where the vast amounts
of video generated on a
daily basis are already
making manual
search
and
discovery hugely
problematic. AI/
ML engines can
be applied in the
news and sports
room to extract
metadata from video as it
is ingested.
Notables at NAB include
a sub-US$4000 appliance
from Axle ai that
integrates face and object
recognition and lowres proxy collaboration
and includes a panel for
Premiere Pro CC. Prime

Veritone for automatic speech-totext transcriptions; Dalet added a
Content Discovery module to its asset
management software for automatic
content tagging, topic extraction and
key phrase searches.
Adobe describes its AI, Sensei, as
a combination of "computational
creativity, experience intelligence and
content understanding" and continues
to apply it to Adobe Premiere Pro.
New at NAB is analysis of colour and
light values from a reference image
which in turn are applied to match a
current shot. The final adjustment can
then be saved as a 'Look' which can be
applied to other shots. Face detection

a live event, augments this with
metadata and will automatically create
clips based on actions, keywords or
logged occurrences. Highlights of a
single event, a particular star player,
or an entire season can be pushed out
to social media.
Still with sports and metadata,
Accedo demonstrated a prototype
of an augmented reality app for live
broadcast sports. Designed to give a
TV viewer a more personalised and
engaging second-screen experience
during long-distance sports events
such as marathons, rally or bicycle
races, the AR-enabled 'bird's eye view'
placed an interactive overview
with real-time updates in the
viewer's physical space through a
tablet or mobile phone.

While much discussion at the
show was given over to the AV1
