Video Clarity’s New Video Analyzer Looks At 4K

Video Clarity has added 4K compatibility to its popular ClearView video quality analyzer product line. The company said ClearView Shuttle 4K was originally designed as a portable, entry-level solution for HD video quality-of-service testing. ClearView Shuttle now includes record and playback capabilities for testing 4K (up to native 4096 x 2160 4K resolution) video with audio.

With the ability to record, play back, and compare sequences of uncompressed 4K video, ClearView Shuttle is intended for device manufacturers and media operators that need to test new encoding technologies and existing processing devices already installed in their operations.

In a typical workflow, the ClearView Shuttle 4K records the 4K source reference video (or an imported 4K file) and then plays back the sequence at up to 60 Hz in real time. The analyzer calculates the segment's video quality score and provides frame-by-frame results to enable a qualitative picture quality evaluation.

“To maintain video and audio quality as compression standards change, everyone along the broadcast chain needs to measure continually the performance of the compression engines on which their day-to-day operations depend,” said Adam Schadle, vice president, Video Clarity. “And now, as more and more devices with 4K capabilities are built and deployed, device manufacturers as well as operators require quality testing with the ability to record at native 4K resolutions in addition to HD and SD formats. ClearView Shuttle 4K is an evolutionary step that provides 4K I/O device and signal path testing at a lower price point with repeatable, objective quality measurements that closely resemble subjective results.”

ClearView Shuttle 4K is a small, lightweight device that can be used in a variety of settings. “Any operation, large or small, from hardware/software designers to end-user producers who work with any kind of compression in standard or high definition, should analyze compression performance to know how their technical and aesthetic choices will look to end users,” Schadle added.
