「...繰り返しになりますが、これはHEVCコーデックの開発に深く関わっている方や、HEVCの機能を習得しようと躍起になっている方にとっては不可欠なツールです...」

Joe Tozer, Zetrox Ltd., author "The Broadcast Engineer's Reference Book"

«As a broadcast consultant and trainer specialising in compression and delivery systems Zond 265 is an invaluable tool for analysing, visualising and demonstrating the various structures, data and buffering in an HEVC stream, the graphical interface is clear, intuitive and easy to use; stream error analysis links directly to the standards documents for quick understanding and debugging. Great tool.»

Victor Klykov, Senior Engineer in Software Development, Skype Video DSP team, Stockholm

«My colleagues and me searched for the HEVC analyzer for developing HEVC codec for a long time. We chose the solution with a great care, in particular, compared various tools. For a variety of reasons (visualization, simplicity, etc.), we decided on Zond 265. The test stream was opened, we checked how the theory corresponded to what should be visualized, and as a result, the work on our own codec was completed successfully. Zond got the highest mark from our team!»

Mark Kogan, Senior Professional Video technology and compression Expert

I am an independent Video technology expert which is very well connected and known in the local and international Video technology market. I was looking for the solution that should serve me for longer terms. Zond 265 was one of many solutions that I have evaluated. I do like Zond 265 as it can show VBV, bitrate and video buffer analysis on GUI and get the reports via CLI. Zond analysis tool, provides a suitable and important information for advance + basic level video analysis with relatively great "user friendly" UI. It is also going to be recommended for all my professional colleagues in the video industry.

Maxim Sharabayko, Senior Video Codec Architect

I appreciate Zond 265 for its informative GUI and powerfull command-line features that allow me to export the required data into JSON format and do further processing. Zond 265 notifyes if there are values of the syntax elements that were coded not compliant to the standard, which serves well.

Neil Hollingum, Perpetual Solutions

«I am using your product now not just in courses on H.265 but also on Adaptive Streaming, H.264, MPEG-Dash and CloudTV to demonstrate the differences in encoding efficiency for different Codec implementation within Azure and AWS as well as freestanding products. The fact that now almost any normal file format is supported and several additional Codecs too, it makes life very easy for us to demonstrate key differences in encoding profiles. You clearly have some very bright and knowledgeable people working on the development of your product and I wish you well in marketing it throughout the Industry.»
