Zond 265 is the first-to-market tool for visual in-depth analysis of HEVC/H.265, AV1, AVC/H.264, MPEG-2 video bitstreams. It's an indispensable solution for developers of HEVC decoding/encoding/transcoding hardware and software. Zond 265 brings along real value boosting R&D and QA processes and reducing validation costs.
It shows in a handy way NAL information, frames types, frames sizes, time stamps, decoding/display order counters, bits distribution between frame elements, coding units data, coding units coefficients, predicted partitions, transform partitions, motion vectors, quantizers, different stages of picture decoding - predicted picture, before deblock filtering, after deblock filtering, and final picture.
Automation mode, reports generation, stream validation and quality measurement are suppoted.

“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. It is also going to be recommended for all my professional colleagues in the video industry.”

- High Dynamic Range (HDR) Detection and analysis. Parsing and interpretation of SEI units
- HEVC screen content coding extension (SCC) (new)
- HRD Buffer Flow: Instant insights into buffer occupancy
- Bitrate Histogram. Bitrate peak values update every second in the course of consecutive frame reading
- Convenient frame-by-frame navigation based on the frame bars in decoding or the display order
- Frames size histogram and color highlighting of different kinds of frames (I, B, P). Marking of reference frames for the current picture
-
Easy-to-use visual presentation of data from all levels of a video stream and decoding stages
- All headers with content. Headers sizes and offsets within a stream
- Highlighting of slice and related headers (SPS, PPS, etc.) that belong to a current frame
- Pixels to be predicted, reconstructed, after deblocking and adaptive loop filtration
- Coding units (CU): coordinates, dimension, and bit-size. Color highlighting different types of CUs (Inter, Intra)
- Prediction units (PU). A spatial prediction mode of intra PU luma and chroma components. Inter PU’s motion vectors, reference lists, reference indexes.
- Transform units (TU): dimension and offset within CU. Luma and chroma coefficients before de-quantization.
- Overlay a frame with a CU, PU, or TU grid and motion vectors
- Gathering and visual presentation of bits distribution statistics to be used while encoding CU, PU, and TU data (skip_mb_flag, merge_flag, mvd, cbf_luma, etc.). Displaying results as a table
-
Quality estimation. VMAF(new), PSNR and MSSIM metrics supported. Quality values can be shown as a visual graph or a map of PSNR for a frame coded tree blocks. Command line interface supports a quality wokrflow
-
Windows, Mac OS and Linux (Ubuntu 12.04 and above) versions of both 32 and 64 bits platforms
-
HEVC specification quotes for most of syntax elements. Just put a mouse pointer to any element name and get an information scope or open a specification at the necessary place
-
Autiomation. Detailed reports, HEVC validation conformance in GUI and CLI
-
Input file formats (Windows version):
- HEVC/H.265 video elementary stream
- AVC/H.264 video elementary stream
- AOMedia Video 1 / AV1 video elementary stream (new)
- MPEG-2 video elementary stream (new)
- MPEG TS with HEVC and AVC
- MP4 with HEVC and AVC
- MP4 Dash segmented/fragmented with HEVC and AVC (new)
- WebM with AV1 video (new)
Mac and Linux version are only support H.265 video
Operating systems supported: Windows XP to Windows 10, Ubuntu Linux 12.04 and above, Mac OS 10.9 and above.
Demo version works for 21 days and is restricted with the first 50 frames to which the analysis is applied. It ships two H.265 and two H.264 test streams.
