Score Your Video Every Step of the Way
Video Clarity has responded to this industry need by enhancing the ClearView product line and releasing version 5.1, which includes
- Preloaded Uncompressed Video Test Patterns
- Sarnoff JND to Objectively Score Your Video
- Scriptable Regression Test Tools with Integration into Microsoft Excel
- Pass/Fail Results against a Threshold
- Simultaneous Record/Playback, Dual Record or Dual Playout.
ClearView ingests virtually any file format and can record directly from DVI, HDMI, Component, Composite, S-Video, and HD/SD SDI interfaces. It stores the audio and video as uncompressed bit-streams for analysis.
The simplest use of ClearView is to compare two video streams side-by-side on the same display under identical conditions, and decide subjectively which one looks better to you. ClearView provides multiple viewing modes, play lists, and all of the usual VCR-like control modes to simplify subjective testing.
ClearView includes the Sarnoff JND objective metric which mimics the human visual system and returns an objective score to indicate the quality of the video. These scores correlate with human viewers 75% of the time based on the Video Quality Experts Group - VQEG research.
After the video is scored using JND or your subjective testing, this score can be compared for regression testing against any number of units. This video will be termed “Gold” hereto after. In this case, ClearView aligns the two video sequences and compares their video quality. Any video sequence, which scores below a user specified threshold, will generate a failure.
All of the metric data is archived into small log files. These log files can be replayed on any ClearView machine with access to the original video sequences, which ensures a repeatable test environment when anomalies are resolved. Further, these log files can be added to the regression testing to ensure that the anomalies stay fixed. For additional convenience, our analysis and graphing tool kit imports these log files into Microsoft Excel for off-line viewing.
“Video Clarity is committed to making automated video QA a reality,” said Bill Reckwerdt, Vice President of Marketing. “Our 5.1 release is a further step towards this reality.”
The ClearView product family is modular in features, and is available direct from VideoClarity or one of our partners. For more information, please visit our solutions pages.
