Telestream Improves Vantage Post Processing

Telestream makes it easier to integrate HDR, color processing, frame rate conversion and more into Vantage transcoding workflows.

These enhancements are said to enable greater and easier integration of Vantage alongside third-party technology, and all of these capabilities (except the connector to Grass Valley Alchemist) are available in the cloud with Vantage Cloud Port. 

With Grass Valley HQX (formerly Canopus HQ/HQX), Telestream Vantage can now perform the task of transcoding acquisition formats to Grass Valley HQX, which are known as intermediate formats used during editing sessions. Vantage can also transcode Grass Valley HQX to delivery formats.

“Editors no longer need to waste time performing these tasks on their editing workstations – Vantage can automate these mundane tasks for them, so they can focus on the creative parts of the workflow,” says Telestream.

For Colorfront, Vantage transcoding now provides customers access to Colorfront Engine advanced color volume remapping tools that use the Human Perceptual Model for multiple display mastering maintaining the original creative intent. 

For media companies that prefer Grass Valley Alchemist for frame rate conversion, a third party connector within Vantage now creates orchestrated workflows that include this technology.

“Grass Valley are excited to provide our shared customers with improved workflow efficiency by having tighter integration with Vantage for our flagship media frame rate conversion product, Alchemist,” commented Martin Jolicoeur, Director Processing Product Management at Grass Valley.

Some of the other enhancements to Vantage transcoding capability include:

  • FFV1 Encoding - FFV1 is a lossless, intra-frame video codec. The encoder and decoder are part of a free, open-source library in the project, FFmpeg. FFV1 is popular for its performance regarding speed and size, compared to other lossless preservation codecs.
  • Sony XAVC – Vantage now supports XAVC HD and HD Intra as well as XAVC 4K and 4K Intra.
  • Automated interface to Harmonic Spectrum video playout servers. While Vantage has worked with this system for some time, Vantage is now able to prepare media files within automated workflows in the cloud, via Vantage Cloud Port.
  • HDR10+ (Vantage already supports SDR/HDR conversions and HDR10). And also, support for AS-11, DVCPro and DVC Pro HD, AV1, Tachyon 9.

“Vantage also offers enhanced, automated composition – no other transcoding solution is able to create and re-time video, audio, and captions and subtitles using a Composition Markup Language (CML) across so many automated workflows,” says Telestream.

Instead of performing repetitive editing tasks to change titles and graphics, for example, users can build compositions to programmatically get the job done. Compositions can be built to trim, segment, stitch, clip, overlay video, transition, cross fade, perform audio-overs, route video, add graphics, re-time and more. The benefit to the customer is they reduce the huge volume of repetitive media composition and editing tasks to a manageable set of automated programs.”

With the updates, Media IO Server now supports 4K UHD capture to drive high-end live production workflows. This provides users with a single capture platform for both HD and 4K UHD signals, simplifying and unifying workflows across the requirements of multiple departments.

In addition, Media IO Server features expanded format support for real-time video editing, adding support for Apple Final Cut X in addition to Adobe Premiere Pro.

Media IO Desktop now supports monitoring of up to 12 channels, double the previous maximum channel count. In addition, the user interface has been redesigned based on client testing and feedback to provide a better user experience for triggering recordings and encoding.

Lisman added: “The most significant aspect of the new Media IO release is its cloud integration features, which give our customers even greater flexibility by allowing them to move key live baseband ingest and video production workflows off-premises. It’s just one more example of how we’re helping media operations prepare for success now and in the future and ensure they can continue to reach the widest audiences on the most platforms.”
