ADVANCED ENCODING AND TRANSCODING • JUNE 2021 SPONSORED CONTENT
W ith the explosion of streaming services, there’s never
been a greater need to prepare high-value VOD content
for viewing across all broadcast and OTT platforms.
The cloud is an obvious solution for supporting this massive
scale. But can these complex workflows including conformance,
transcoding, packaging, and QC run securely in the cloud and
integrate seamlessly with existing media supply chains?
Yes, with Encoding.com.
The industry’s most trusted cloud media processing platform,
Encoding.com offers a comprehensive set of B2B microservices
focused on the fast output of broadcast-ready VOD content
for media supply chains. With just a few lines of JSON or XML,
our API makes it easy to transcode and package VOD assets
from nearly any source material, and then stream it with the
confidence that it will pass the most stringent of conformance
checks and be free of errors during playout on all linear systems
and OTT devices.
Encoding.com support for B2B workflows includes MPEG-2,
XDCAM, XAVC, and ProRes transcodes, as well as passthrough
muxing of pre-encoded content. All frame rates and resolutions
are supported, as well as offering advanced filters for interlacing,
pulldown, and de-interlacing content, along with explicit support
for marking or modifying color space parameters.
We’ve also developed a number of automated features
specifically for media supply chain processing, including
the following:
• CableLabs compliance
• Complex multi-channel audio management
• Caption extraction, modification and insertion
• Conformance and assembly
• BATON and proprietary QC
• Advanced source clipping
• Black-frame trimming and padding
CABLELABS COMPLIANCEProducing content for linear or VOD playout that is compatible
with the breadth of CableLabs standards is often considered the
exclusive domain of proprietary on-premises video workflow
systems. But these systems require expensive investments to
purchase, maintain and replace on regular schedules, and,
because of restrictive licensing models and rigid deployment
frameworks, do not integrate well with content-prep platforms that
have migrated to and benefit from the efficiencies of operating
in the cloud. The Encoding.com API resolves those issues.
A simple API call to produce CableLabs output will handle the
vast majority of requirements for playback devices, but expansive
support for systems that vary from the standard or possess other
specific requirements are also supported. Transport stream
parameters can be modified, including PID, PCR deltas and
presence, PAT/PMT frequency and versioning. The same deep
exposure we provide for D2C video codec parameters is also
present for B2B transport streams, with hundreds of options
available in case a specific parameter needs to be overridden.
MULTI-CHANNEL AUDIO MANAGEMENTCommonly, audio data from multiple sources arrives for
assembly and final processing with very little consistency.
Camera formats, editing software, and satellite feeds can have

between two and 16 actual audio tracks, each of which may
contain anywhere from one to 16 audio channels, resulting in
a huge range of possible combinations. Inaccurate or missing
metadata is also common. Not surprisingly, many broadcasters
and streaming media companies run into conformance
violations that fall upon editors to fix. What’s more, once
assembly is completed, bringing the composite asset into
conformance across all audio tracks, languages, and channel
layouts requires a significant person-hour investment.
An Encoding.com workflow automates the process of
identifying known and unknown variants of all provided audio
assets. We support both lossless and lossy codecs through
commercial and open-source audio engines. Codec support
includes PCM, Dolby Digital (AC-3), Dolby Digital Plus (E-AC-3),
Dolby Atmos, AAC LC/HE/HEv2, MPEG-2, and MP3, among
others. Loudness normalization is also available for these
outputs, and Nielsen watermarking can be applied wherever
needed. Outputs can be downmixed or layouts inferred from
other fixed surround information, as well.
CLOSED CAPTIONS AND SUBTITLINGThe Encoding.com API lets you automate the manipulation and
conversion of the most-used caption formats, including extracting
and modifying multiple caption services and languages. You
can re-time captions, modify caption frame rates to match your
content, upconvert from EIA-608 to 708, and convert captions to
a broad range of formats, letting your engineers break away from
traditionally mundane manual tasks in desktop applications.
In addition to rich support for sidecar and fragmented/
packaged caption data for common formats such as fMP4 and
HLS, we offer the ability to extract and insert a variety of ancillary
and frame-based caption formats, including SCTE 128, SCTE 20,
DVB, and SMPTE 334-2. Whether inside CableLabs-compliant
transport streams, MPEG-2 program and transport streams,
MXF containers, or H.264 and H.265 video streams, your video
processing workflow can now support caption requirements for
content distribution to all broadcast and OTT devices.
CONFORMANCE AND ASSEMBLYEncoding.com supports a comprehensive and growing
portfolio of origin and playout standards to fully automate the
task of content conformance. We also enable the preparation
of master camera or edit files targeting various distributors with
features that let you trim leaders; physically insert, replace and/
or remove ads and titles; stitch videos together; and more.
Specific to edit workflows, Encoding.com users can take
standard broadcast/camera codec, mezzanine, and delivery
files and apply frame-accurate trim, splice, and concatenation
rules. Black/solid color and silence generation conforming to
the output spec is also available. Timecode can be modified to
support the same frame rate or retimed content. With support
for high-end broadcast containers and codecs, these workflows
produce output that’s as lossless as the ingested material.
BATON QCInterra Systems’ BATON is an AI-enabled automated QC
platform that provides comprehensive quality and compliance
checks for VOD content for linear and streaming workflows.
The BATON test suite is now integrated into Encoding.com’s
automated QC service, allowing you to run custom BATON test
plans or report templates and generate a PDF or HTML report.
ADVANCED SOURCE CLIPPINGWhen concatenating source files, the ability to trim each
source part individually can be a real time-saver. Our platform
makes it possible to automatically combine a segment from one
source with another segment from a second source, a capability
that can shave minutes, if not hours, off the workflow.
BLACK FRAME TRIMMING AND PADDINGOur new black-frame-detection capabilities let you detect
and trim black frames from the start and end of the video.
Black frame padding is also available for appending a specified
number of black frames before and after the output video. If
closed captions or audio channels are present, they will be
trimmed or padded accordingly.
