VQLab 1.2 Download Trial Now!

VQLab is a fast, reliable and cost-effective tool for assessing the quality of your processed video. With native support for a wide range of video formats: AVI, MPEG-2, MPEG-4, AVC/H.264, VC1, DV, raw YUV format (supported fourCC: YV12, UYVY, AYUV, YUY2, YVYU, YVU9, Y211, Y41P, IYUV, CLJR, I420), VQLab can also be used to analyse any other video format supported by the DirectShow framework installed on a target machine. VQLab uses the PSNR, SSIM and CZD metrics in order to provide an accurate, objective measure of the video quality. The metric data generated can be easily displayed, sorted, filtered, compared, visualized and exported.

VQLab's robust, multi-threaded implementation delivers excellent speed performance and can take full advantage of the new multi-core/multi-processor computer systems.

Key Features

• Fast, reliable PSNR, SSIM and CZD measurements
• Native support for a wide range of encoding standards: MPEG-2, MPEG-4, AVC/ H.264, VC1, DV, raw YUV format (supported fourCC: YV12, UYVY, AYUV, YUY2, YVYU, YVU9, Y211, Y41P, IYUV, CLJR, I420)
• Fully configurable test environment for reliable, reproducible test results
• Advanced reporting capabilities allowing rapid encoder profiling and quality performance comparisons, by using the powerful VQLab Results Viewer .
• DirectShow support for easy interoperability with 3rd party decoders and demultiplexers
• Test automation friendly and powerful VQLab CLI
• Supported OSs: Windows Vista, Windows XP, Windows Server 2003
  

Key Benefits

VQLab can automate the video quality control stage and deliver the following benefits:

• Reduced time-to-market - the operator will now spend just a fraction of time for checking video quality. VQLab can work non-stop in batch mode allowing measurements to be made overnight, during week-ends etc.
• Increased quality - during visual inspection the human operators can miss less obvious, isolated quality problems. VQLab will check and report quality metrics for each single frame so all quality issues are identified.
• More efficient usage of the delivery medium - VQLab's very tight control of the video quality allows the operator to bring down the bitrate to the lowest possible level so more content can be delivered on the same delivery medium.

Target Applications

• Codec development and testing
• IPTV testing
• Quality control in digital video processing environments (post production, content creation etc.)
  

Customer feedback:

"VQLab is the key tool which helps us deliver great quality encoders to our customers, filling an important gap in the development and analysis of video compression systems. Once we tried VQLab from SEMACA, it quickly became an integral part of the development & QA process for our Accelera HD H.264 video compression products. As we constantly improve the quality of our algorithms, VQLab provides us with a fast, reliable, and simple platform for analysing the quality of our streams. The flexibility of the tool makes it valuable to our engineering teams during interactive algorithm development, and the automated test framework makes it a key part of our pre-release QA processes."
