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 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.
