Quasar not only ensures your content security through 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.
Performing QC on a large content volume can be time consuming. Quasar auto scales to support varying content volumes and can process thousands of files simultaneously and quickly.
With IAM cross-roles, pre-authenticated URL, whitelisting for REST API and other security features, you need not worry about your content security. Further, auto provisioning of virtual machine in content region ensures faster content QC.
Advanced monitoring for early detection of potential problems, detailed system logging to trace back any rare issues, and failover mechanisms allowing workflow continuity even with infrastructure failures make Quasar a reliable service.
Quasar is available as a fully managed SaaS service. This eliminates the need of any staff for system management, thus, reducing your time and cost. You can also deploy it in your own Virtual Private Cloud (VPC).
Quasar allows for a side-by-side comparison of a media file with its master/reference file using SSIM, PSNR and Ref-Q™, providing an efficient and cost-effective means of getting a frame-by-frame report of all such differences. This reduces manual inspection costs and increases the accuracy of the results.
Quasar supports QC checks for formats like MPEG-DASH, Apple HLS, Microsoft Smooth Streaming, and fragmented MP4 in addition to support for broadcast formats. You can auto-assign different QC templates to different encoding files to perform your video QC.
Harding FPA engine is integrated into Quasar QC checks allowing users to perform Photosensitive Epilepsy Validation using the industry defacto standard Harding PSE and receive a valid Harding certificate for HDR and SDR content.
QCtudio provides the ability to enhance your QC processes and elevate QC efficiency. Now you can review Quasar's results in an innovative interactive interface on a video timeline, adding comments for further collaboration, and modifying alert categories for precision. You can export updated reports in XML/PDF as well as in formats compatible with NLE solutions.
