Corporate Profile
Today almost all video and audio are produced and transported as compressed streams, often heavily so. We sweat bullets to create pristine digital-A/V signals that we squeeze down little pipes and dump into small bit buckets!To maintain quality as compression standards change, everyone along the chain needs to constantly measure the performance of the compression engines on which day-to-day operations depend. "Digital compression" means having to make choices, including temporal resolution vs. noise, spatial resolution vs. image size, and luminance/color range vs. gamut. 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 subjectively and objectively analyze compression performance to know how their technical and aesthetic choices will look to end-users.
Video Clarity's ClearView system offers a set of video quality analysis tools for software developers, hardware designers, QA/QC engineers, video researchers, and production/distribution facilities. ClearView records, displays, and then objectively and subjectively analyzes processed video. The device can capture video content from virtually any source-file or digital or analog source such as SDI, HD-SDI, DVI, VGA, HDMI, component, composite, or S-video. Regardless of the input, ClearView can ingest and convert it to fully uncompressed 4:2:2 Y'CbCr, 4:4:4 RGB, ARGB, or RGBA.
For subjective analysis, multiple video sequences can be shown on the same display in a split-screen, seamless-split, split-mirror (butterfly), or A-B (source minus result) mode. Playback supports zoom, jog, shuttle, and pause for in-depth analysis. The device also has a multi-clip playlist capability.
