Vantage Advantage: IMF File Production, Delivery Simplified

0

Enhancements to Telestream‘s CaptionMaker authoring software and the Vantage Media Processing Platform have been brought to market.


They provide “all the production tools” required by major broadcast networks and content distributors who have standardized on the Interoperable Master Format file-based delivery format.

In particular, CaptionMaker and Vantage Timed Text Flip now support IMSC 1.1, the latest
version of the SMPTE standard for subtitling and captioning.

IMSC is of particular importance in the preparation of IMF packages, and Telestream says no other technology vendor offers workflow automation combined with the caption and subtitle processing capabilities offered in Vantage and CaptionMaker.

“Using CaptionMaker, users can author, edit, encode and repurpose video captions and subtitles,” it says.

Then, using Vantage, they can include these media files in automated workflows for file transformation as needed when creating primary and supplemental IMF packages.

“With CaptionMaker, users create video captions and subtitles for television, web and mobile delivery,” Telestream notes. “CaptionMaker simplifies the process of complying with government regulations, enabling greater access to broadcast content for television, online and mobile viewers. The latest release supports IMSC 1.1 and contains several other enhancements including improved caption and subtitle rendering that makes them crisper and easier to read.”

Also, Vantage Timed Text Flip provides full support for IMSC, including version 1.1. IMSC is
required for IMF packages. Users that need to deliver video content to TV or Internet can
use Vantage and Timed Text Flip to transcode captions and subtitles with their media within
a single, automated workflow. This type of automation can help a variety of organizations
meet government mandates in a file-based workflow.

In addition, Vantage IMF Producer automates the creation of IMF packages from Adobe
Premiere Pro. Using a Vantage panel within Adobe Premiere Pro provides direct access
and significant workflow efficiencies for editors. IMF Producer automates the creation of all
files required in an IMF package from a single output render of an Adobe Premiere Pro
timeline. As well as generating the primary package, editors can create additional
sequences, which become supplemental IMF packages that contain different versions of
audio, subtitles, edit points, Dolby Vision HDR metadata and more.

“As a file-based delivery format, IMF is gaining widespread support from the media industry, so the decision to focus our efforts on developing IMF production tools was straightforward,” says Scott Matics, Senior Director of Product Management at Telestream. “However, these are not just any old IMF productions tools – they reflect Telestream’s outstanding expertise in this area and a great depth of customer feedback.”
