Zond 265 main window
Controls "Display list of recently opened files", "Copy current file path to clipboard", "Open current file location" are not available when running Zond 265 on a remote computer.
Red blocks on the decoded picture window mean intra prediction units, blueblocks mean inter uniprediction units, green blocks mean inter biprediction units, white blocks mean inter skip predictrion units Transform partitions.
White blocks on the decoded picture window mean luma sample transform blocks, blue blocks mean blue-difference chroma sample transform blocks,red blocks mean red-difference chroma sample transform blocks Motion vectors.

Controls "Picture type", "Color components", "Transform partitions", "Compression details", "Video window scale", "Navigation mode" show drop-down lists with options listed below.
Matrices of transform coefficients are placed on the TU tab of the details window.
These parameters are also presented on the CU tab of the details window.
Video window scale
These commands set a scale of the decoded picture window.
The tab contains information about all NAL units of the file.
By clicking on a row of the "Bitstream" tab you can see parameters of the unit.
Meaning of row colors are listed in the following table. All NAL units belonging to the current frame are highlighted by a brighter color.
The tab contains the following statistical data about the decoding process of the current frame: bit distribution (mvd, residuals, merge_idx etc.), number of intra and inter pixels, distribution of predicted units and transformation block sizes, data about compression efficiency (compression ratio, bits per pixel, motion vectors per pixel etc.).
The meaning of the first two columns of "Elements" table is listed below.
The tab contains data about all NAL units belonging to the current frame.
The tab contains more detailed information about a coded unit than available in the decoded picture window.
The tab contains more detailed information about all transform blocks of the highlighted coded unit than available in the decoded picture window.
The tab contains the following statistical data about the decoding process of the file as a whole: General data of the file such as bitrate, average frame sizes, resolution, number of frames as well as statistical data for all frames such as bit distribution (mvd, residuals, merge_idx etc.), number of intra and inter pixels, distribution of predicted units and transformation block sizes, data about compression efficiency (compression ratio, bits per pixel, motion vectors per pixel etc.).
Frame size bar chart
Red bars mean frames that contain only intra slices, blue bars mean frames that contain inter uniprediction slices, green bars mean frames that contain inter biprediction slices. By clicking on a bar you can navigate to the frame with the number displayed at the top of that specific barMarks of reference frames.
The color depends on the distance from the current frame. Near frames are colored with greenhues, more remote frames are colored with yellow hues, the most remote frames are colored with red hues. These colors are the same as on the RefIdx layer of the decoded picture window. Reference frames of the current coded unit are marked by an arrow
Buffer size statistics
The tab contains a buffer fullness plot for hypothetical reference decoder when decoding video of given frame rate transmitted at given bit rate using given initial delay and buffer size. Overflow and underflow areas are filled by red color.
The values of controls "Buffer size", "Bit rate", "Frame rate", "Initial delay" can be edited manually. If you have doubt about one of the values you may set a zero value and Zond 265 will try to calculate it on the basis of the given video.
