Quasar Cloud Video QC Software – Overview
With file-based workflows increasingly moving to the cloud, it is only natural to have your file-based QC process within the cloud as well, taking advantage of the scalability and efficient resource planning inherent in the native cloud applications.
Quasar® is the first file QC service built natively for the cloud architecture. Quasar® helps you perform file-based QC on your cloud assets with ease. Encompassing all the latest features of Pulsar; industry’s most efficient audio and video quality control software used by many large media corporations worldwide; Quasar® video quality checker promises the fastest rate of QC in the cloud.
Quasar® cloud based quality control service ensures that your content is secure while it is processed, using a range of security measures such as IAM cross-account roles, whitelisting and pre-authenticated URL. It is the most advanced cloud video QC software with support for advanced features such as HDR, IMF/DCP analysis, Adaptive bitrate QC, Harding PSE etc. Quasar® File QC can be used to verify the content before submitting to key VOD services such as Netflix, Amazon Prime Video, iTunes and HBO.
Features & Benefits
Quasar® is an elastic system that can be auto scaled to any size without needing users’ intervention allowing hundreds of files being processed simultaneously. Performing QC on large content library or a content burst can be very time-consuming. With Quasar®, you never have to worry about varying content volumes. Just post them to Quasar® for processing and it will be processed quickly. The QC jobs that would take months to process can be processed in just a few days.

Security & Latency
One of the biggest concerns for content QC on Cloud is the content security. Along with that, the content latency is also an important consideration. Following capabilities are available in Quasar® to address these issues:
- IAM cross-roles support
- Pre-authenticated URL
- Temporary security credentials
- No storage of user’s credentials anywhere in the Quasar® system
- No access to user’s content and the processing VMs
- Whitelisting for REST API access
- Auto provisioning of virtual machine in the content region. This has the following benefits
- No inter-region latency allowing faster cloud video content QC
- No egress charges
- Compliance with local laws that may prohibit the content movement outside the country/region
Quasar® is a highly reliable service that has implemented a large number of service recommendations in terms of service reliability and security.
- Advanced monitoring for early detection of any potential problems in the service performance
- Detailed system logging allowing us to trace back any rare issues
- Failover mechanisms allowing the workflow continuity in case of infrastructure failures
Quasar® service is available as fully managed SaaS service as well as a Private edition that users can deploy in their own virtual private cloud (VPC).
Following are the key benefits of using SaaS service:
- Users don’t need to engage any of their staff for system mgmt. This alone can save significant time & cost for users, while focusing on their core business.
- Users can immediately start using the Quasar® system – either manually or via REST API.
- Committed SLAs for service upkeep.
Ref-Q™ is a reference-based technology, allowing the ability for an automated side-by-side comparison of a file with its master/reference file, reporting back any discrepancies. For example, by comparing a media file with its master file, Ref-Q™ can automatically detect artifacts introduced in the file due to transcoding or other processes. Similarly it can also report any frame that includes signs or text in primary language which is replaced with a similar frame in the local language.
Ref-Q™ automates this previously manual (and error prone) comparison process, providing an efficient and cost effective automated means of getting a frame by frame report of all such differences, reducing manual inspection costs, and increasing the accuracy of the results.
In addition to support for broadcast formats, Quasar® supports VOD formats such as adaptive bitrate formats and fragmented MP4. 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
We have integrated Harding FPA engine within Quasar®. This allows users to perform Photosensitive Epilepsy validation using the industry defacto standard Harding PSE. Users will also receive a valid Harding certificate for every file processed via Quasar®.
