The main features of VQInsider are:
Audio & Video Quality Measurement
Cause Analysis and Improvement Suggestions
Audio and Video Playback, Video Zoom
XML Remote API
Audio & Video Quality Measurement:
The VQInsider provides passive, offline analysis for media applications; frame-based user experience video metrics that enable a per-frame analysis of video calls for detailed examination.
Video streams can be viewed frame by frame or complete with synchronized audio. Video quality diagnostics and troubleshooting employ either Wireshark capture files or 3GP file formats.
H.263, H.263+, H.264, Mpeg4, 3GP, MP4
QCIF, CIF, VGA, 4CIF, 16CIF, 480p, 720p, 1080p
NAL-Unit, STAP-A, FU-A

Audio & Video KPI:
Video MOS, Network KPI, Profile, frame rate, Intra-Partial frame, Image
Complexity, Compression, Audio MOS, Packet Size, Bandwidth, Packet Loss, Duplicate packets, frame rate, Jitter, etc.
Audio and Video MOS
is typically used to evaluate voice and video quality in multimedia, especially when codecs are used to compress the bandwidth. MOS is the arithmetic mean of all individual scores ranging from 1 (bad) to 5 (excellent). Separate MOS values are used to evaluate voice and video quality.
This method used in VQInsider is based on objective and subjective parameters measurement technologies, taking the compression level and network element into consideration. VQInsider supports multiple audio codecs and video codecs: H.263, H.263+, H.264, MPEG4, SD, HD
XML Remote API:
VQInsider is designed to be controlled directly by the user. However, it can also be controlled by a third-party application. This can be done through the command line interface or by employing the TCP/XML API and XML commands. When controlled by the third party application, the third-party (rather than the user) instructs the application to execute requested operations. Thus, the VQInsider can perform fully automated testing without user intervention. This automation reduces the need for user intervention, which in turn results in reduced timeto- market.
VQInsider allows you to build reports according to your specific requirements and export them. The results can be viewed in either summary or detailed format. The Report Builder offers various built-in templates as a basis for your custom-made Test Results Report, which can be viewed as a graph or table. You can zoom into a section of the graph that you want to examine, and export the report to JPEG, PDF, Excel or XML formats.
