Vectorscope - Color accurate graticules automatically switch between SD (601), HD (709) and 4K/QHD (709 or 2020) color spaces. The markers include color points (for standard bar checks) at 75% and 100% saturation. All the standard points are boxed; red, magenta, blue, cyan, green and yellow. A skin tone/flesh line is provided to allow for easy hue adjustment as well as standard diagonals.
Waveform YCbCr - Displays the levels of the Y, Cb and Cr from the left of the picture to the right of the picture with all the lines summed into one graph. The Y, or luma/luminance, graph provides accurate white and black level information, as well as the range in between. The luma waveform supports standard, HDR10 (Dolby Vision /ST.2084) and HLG (Hybrid Log Gamma) display up to 10,000 nits.
Waveform Luma/NIT Light Level - Displays the overall intensity of the picture. Standard 601/709 levels are supported, as well as NITs display for HDR/ST 2084 and HLG signals.
Waveform YCbCr Parade - Displays the levels of the Y, Cb and Cr from the left of the picture to the right of the picture with all the lines summed into one graph. The Y, or luma/luminance, graph provides accurate white and black level information, as well as the range in between.
Waveform RGB - The RGB Waveform Monitor shows each of the red, green and blue signals as independent graphs, displaying the RGB, or chrominance/color values associated with the signal. Above is the stacked waveform, a parade waveform is also available.
Waveform RGB Parade - The RGB Waveform Monitor shows each of the red, green and blue signals as independent graphs, displaying the RGB, or chrominance/color values associated with the signal. Above is the parade waveform, a stacked waveform is also available.
Waveform RGB Overlay - The RGB Waveform Overlay Monitor shows each of the red, green and blue signals on the same graphs, displaying the RGB values associated with the signal. This view makes color and white balancing simpler.
Waveform High/Low - The Waveform Monitor in high/low mode allows the colorist to focus just on the blacks and peaking levels in the signal. Traditional scopes can zoom into one or the other, but this view gives access to both at the same time.
CIE XY Gamut - The CIE XY Gamut, or chromaticity, scope provides a visual representation of the color in a video across all the colors of visible light. For a particular YCbCr range (BT.2020, P3, Rec.709, CCIR-601) a triangle can be superimposed to show the colors that fall within the acceptable range and those that are outside it. The color of the video within the CIE 1931 color display can be white, black, or the chromaticity hued background.
Histogram - The Histogram shows the distribution of red/green/blue, Y/Cb/Cr or hue/sat/luma within the signal as a series of discrete bars that make a continuous graph for each color. This display provides an overview of the tonal range of each color in the picture. Each bar is the count of the number of pixels for one of the 256/1024/4096 possible bins.
Histogram YCbCr - This histogram breaks up the signal in into luma and chroma components. The top histogram represents the luma power of the various levels in the signal. The Cb and Cr histograms that follow show the power distribution for those two components. A separate RGB histogram display is also available.
H/S Scope - The H/S Scope allows easy calibration of lighting or camera to a standard DSC ChromaDuMonde chart. The target color level or saturation is calibrated to a single horizontal line in the chart. The color hue component is mapped horizontally, with standard 601, 709 or 2020 targets as vertical lines.
Data View - The Data view allows access to the raw pixel values being monitored on the HDMI or SDI input. Raw values are captured and displayed with no manipulation by the software. This mode is perfect for checking vertical blank signalling and metadata, as well as picture issues like inner line sync markers or out of range colors. Pixel starts can be selected, along with lines, in the edit boxes above the data area.
Status - The Status view presents real time data on the overall signal in terms of gamut, maximum and minimum chroma and luma, audio levels and MaxFALL/MaxCLL for HDR signals. Any issues detected by the status panel are automatically entered in the log file and window with time, type, source and reason.
Audio Meters - Up to 16 audio channel metering is supported. Meter types include dbFS, SMPTE RP-155, EBU R-86, Loudness (at +9 or +18) and PPM wth EBU or BCC markings.
Audio Phase - The audio phase meter shows the relative density of two audio channels and the relative loudness as a line moving towards the louder channel.
Audio Vector Lissajous - The audio phase meter shows the relative density of two audio channels and the relative loudness as a line moving towards the louder channel.
Audio Vector Lissajous XY - The audio phase meter shows the relative density of two audio channels and the relative loudness as a line moving towards the louder channel.
Audio Histogram Linear - The audio histogram displays a bar chart of the levels of the components of an audio signal.
Audio Histogram Linear Reverse Log - The audio histogram displays a bar chart of the levels of the components of an audio signal.
Audio Histogram Log - The audio histogram displays a bar chart of the levels of the components of an audio signal.
Waveform - The waveform displays the selected pair's audio as a standard wave.
The Picture view shows the video signal, to confirm the source is correct and to display time code location. Action Safe, Title Safe, Graphic Safe, Picture Frame, and Active Region graticules are optionally available.
Luma - Show only the Y or brightness of the picture.
Red - Show only the red channel.
Green - Show only the green channel.
Blue - Show only the blue channel.
Zebra Luma - Draw zebra bars where the luma is too high or too low.
Zebra Chroma - Draw zebra bars where the chroma is out of range.
Clipping - Draw green anywhere the signal is too high or too low.
Edge Difference - Highlight every edge in the picture.
Focus Assist - Show areas of the image that are in focus.
Flip/Flop - Flip the picture horizontally or vertically.
False Color - Show each exposure level as a color. See Here for details.
Luma Key - Show the video luma keyed over a checkerboard or image.
Green Screen - Show the image green screen keyed over a checkerboard.
Green Screen Despill - Show the image green screen keyed with edge despilling over a checkerboard.
Closed Caption Detection and Display - Decode closed captions from line 21 encoding (SD) and line 9 ANC encoding (HD). SD 608, HD 708 and OP-47 can all be decoded in real time and displayed as text over the picture. The actual data can also be viewed on line 9, or 21 for SD, in data mode. CC type detection is also displayed.
Error Log Window - The error logging review window displays the video and audio errors from the log stored on disk. These include loudness overages, out of gamut, luma too high/low, chroma too high/low, broadcast illegal colors, repeating lines, saturation errors, signal loss and recovery, and other error detection.
8 Bit Signal - 8 bit signal processing is supported, including detection of 8 bit signals in a 10 bit path (note the missing lines/bins).
10/12 Bit Signal - Smooth scopes on true 10 and 12 bit signals display every possible level in the signal, allowing finer analysis.
HTTP/Web Server - Check the status of your facility from anywhere with our live HTTP/Web page interface. Real time updates in pure HTML5 without any extra plugins.
Remote Desktop Access - You can also control and view using standard remote desktop tools to create a full featured monitor for your entire facility. This video tutorial gives an overview of setting up a remote system with an AJA U-TAP and KUMO series router.
Zoom and Pan - The waveform monitors and vectorscope zoom in for a closer look at low saturation signals, or the luma elements of the waveform. The live picture can also be zoomed in or out, and panned with the mouse. To zoom, roll the mouse wheel. To pan, click and drag. To reset to normal view, right click the mouse. Specific 1x, 2x and exact decimal zooms are also available in the config dialog.
Signal Compare - The signal compare feature can be used to freeze a complete frame of video (two fields in interlaced), every second line (field), or at a 50/50 dissolve to compare two signals or cameras. Once frozen, all the standard scopes are still available for setup and comparison. While a frame is frozen, the comparison mode and type of scope can be changed.
User Markers, Lines, Circles and Boxes - Users can place plus sign markers (+) and lines on any of the scopes, that will persist to help make exact measurements between different signals.
Raw and JPEG Capture - The incoming image can be captured as a raw (YUV, V210, RGB10) image in full, bit perfect image or a JPEG version for easy sharing. The entire scope's interface can also be captured.
Full HDR Support - Along with Rec 709, both SMPTE 2084/HDR10 and HLG luminance HDR profiles are supported. BT.2020/WCG is also supported to allow analysis of full color WCG, as well as in contained color display standards list P3.
Loudness and RMS Metering - All audio meters can be set for EBU9 or EBU18 loudness monitoring, as well as RMS/peak. The status window also supports loudness as a floating point value, and any excursions are automatically collected in the on disk error log.
Vertical Blank Analysis - Up to 32 lines of vertical blank can be analyzed along with the active picture. Captions, time code and other decodable metadata is automatically detected. Any SMPTE DID/SDID packets found are highlighted in the HEX Data view.
Line and Region Select - as well as full picture analysis, the scopes can be set to analyze a single line or a rectangular area of the picture, to detect finer detail errors.
Time Code - read multiple time code types simultaneously and display them in the lower third data area. RP-188 VITC and LTC, SMPTE LTC (analog), vertical blank encoded VITC and RP-215 film KLV time code are all supported.
Full Screen Mode - Double clicking on the interface will put 4KScope into full screen mode. This maximizes the space for the scopes and the picture, but maintains a time code info line at the bottom of the monitor.
