«...Again, if you're deep into HEVC codec development, or really into learning about how HEVC works, it's an essential tool...»

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.»

The video analyzer Zond 265 is a professional product  and a powerful toolset which allows a user to easily identify visual artifacts or bitstream compliance problems, see the video encoding elements. This software from Solveig Multimedia is designed for a comprehensive analysis of the video streams.

When the tool first appeared support of the HEVC / H.265 video standard analysis was the main video analyzer feature. Therefore initially the software was especially useful for developers. With its help they were able to create programs and codecs compatible with HEVC / H.265.

Main features of the video analysis with Zond 265

  • Estimate video compression quality based on several popular metrics - Netflix VMAF, PSNR and MSSIM with the video quality analyzer.
  • Observe the instant buffer fullness.
  • Get complete information about the file (including profile, level, croma subsampling, color bit depth, video stream resolution format, aspect ratio, number of bits used for data transmission / processing per unit of time, frame rate) as well as information about HDR, compression efficiency, GOP length statistics.
  • Obtain a graph of the statistical distribution of frame size and color identification of different types of frames (I, B, P).
  • Analyze bit distribution. In the course of video analysis you get access to the statistics and visualization of bits distribution that were used for coding CU, PU and TU data, followed by displaying the results as a table.
  • Detect errors in the HEVC stream, etc.

The video analyzer Zond 265 advantages

  1. Intuitive video analysis. The program is optimized and provides video statistics in a form visually convenient for both video streams and decoding steps. This greatly facilitates the verification.
  2. Convenient frame bars navigation in the decoding order of the display order.
  3. Reference frame marking for the current image is available.
  4. Easy to use interface.
  5. Large number of supported video formats ー elementary video streams H.265 / HEVC, EVC, H.264 / AVC and AV1 (AOMedia Video), MPEG-2 Transport Stream for HEVC / H.265 and AVC / H.264 video, MP4 (MPEG-4 Part 12) with HEVC / H.265, AVC / H.264 and AV1 video streams.
  6. Possibility to download the video analyzer software and to check the functionality within the demo version for free.

Zond 265 by Solveig Multimedia is a perfect tool for inspecting video files, analyzing video codecs, bitstream, decoding steps, etc. You can get complete information about the video file with its help. Download, install and use it ー you won't regret your choice!
