Products Features & Benefits

Fast & Scalable

Fastest QC system in the market with up to 6x faster than real-time analysis speed for HD content and near real-time analysis for JPEG-2000 4K content. Faster QC results into lesser licenses for a given content volume with direct impact on investment in the QC system. It also improves the workflow throughput with quicker access to QC results. You can also easily setup a verification cluster with multiple QC verification units for higher system throughput.

High Dynamic Range

Perform QC of your Dolby-Vision, HDR-10 and HDR-10+ content. You can perform a variety of metadata validation checks along with detailed reporting of HDR parameters. You can also cross-check the video properties between the HDR metadata and the video essence. The HDR toolset in Pulsar is the most comprehensive and can significantly aid in setting up & managing your HDR workflows efficiently.

Interoperable Master Format (IMF)

Pulsar has the most comprehensive support for IMF packages. Some of the key capabilities include:

  • Support for Application# 2E and SMPTE TSP 2121
  • Package validation
  • Supplementary package support
  • CPL and OPL based validation
  • Sidecar composition map validation
  • Photon integration
VOD and Adaptive Bitrate

With built-in support for adaptive bitrate formats as well as fragmented MP4, Pulsar allows users to automate the QC of Video-on-demand assets. Key capabilities include:

  • Formats. MPEG-DASH, Apple HLS and Microsoft Smooth Streaming
  • Encrypted packages support.
  • Auto-assignment of different QC templates to different encoding profiles.
  • Adaptive bitrate package specific checks to help validate the integrity of ABR packages.

Ensure that your content is compliant with country regulations as well as against your customer specifications.

  • Photosensitive Epilepsy using Harding PSE engine & get a Harding certificate for every job.
  • Compliance with Audio loudness against CALM act, EBU R128 and OP-59 recommendations.
  • Compliance with legal luminance & chrominance range or RGB Gamuts.
  • Compliance against presence of Emergency Alert System (EAS) messages in the content.
  • Compliance against Netflix, iTunes, DPP, ARD-ZDF and many other organizations using our ready-to-use factory templates.
Track Layout

Many content application such as Advertisement content delivery, requires certain content segments to be present at head and tail of the content. These content segments may include color bars, black frames, freeze frames, slates, audio mute, tones and silence. You can setup your custom track layouts and validate the overall structure. This can be done in conjunction with the template checks.

Customer Testimonials

Vincent S. Lyons
Vice President of Digital Media Services, Encompass Digital Media

In Pulsar we have found the combination of simplicity, performance and features that we have been looking for in a media file QC software

Vice President of Digital Media Services, Encompass Digital Media

Michael Mallozzi
VP of Broadcast Engineering & System Design, AMC Networks

Given our positive experience with our initial Pulsar installation in improving the quality of the content in our file-based workflow, as well as Venera’s ongoing support and responsiveness to our requests since our first Pulsar installation in 2013, we chose to expand our QC operations with additional Pulsar systems, which we have found provide us the best value and ROI.

Heiki Mannik
Coordinator of Digital Archiving, Estonian Public Broadcasting

Pulsar is an important addition to our infrastructure and will help us obtain higher operational efficiencies from our content workflows. We looked at major QC players in the market and selected Pulsar because of its high performance and accuracy of results. As Public Broadcaster, we verify new material coming daily from production and will use Pulsar for that but even more important role of Pulsar would be to keep an eye on large volumes of old archive material being mass-digitized from analogue tapes with its QC reports

Quasar did save me considerable time this week in some last minute QC of live streamed content and found 3 issues that needed to be addressed. The speed and flexibility of Quasar processing was essential as the QC ran in a small window before going live.
