Zond 265 at Mac App Store analyse

Zond 265 is the first-to-market tool for visual in-depth analysis of HEVC/H.265 video bitstreams. Its 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. Features: • 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.) • Quality estimation. 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 • 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 • HEVC stream validation conformance according to the specification in GUI and CLI Input file formats: • HEVC/H.265 video elementary stream • MPEG transport stream with HEVC/H.265 video streams • MP4 (MPEG-4 Part 12) files with HEVC/H.265 video streams The subscription is valid for one month. It removes the limitation to analyze only first 50 frames. The price is $149.99.
