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.

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 trace can be white, black, or the chromaticity hued background.

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.

Histogram YCbCr - The Histogram YCbCr / YUV scope displays the luminance, and both chroma signals stacked top to bottom. Y is the luma component and Cb and Cr are the blue-difference and red-difference chroma components. .

Histogram Luma - The Luma Histogram shows the distribution of luminance within the signal as a series of discrete bars that make a continuous graph. This display provides an overview of the tonal range of each color in the picture.

Histogram RGB - The Histogram RGB scope displays each of the R, G, and B (red, green, and blue) channel values stacked top to bottom. RGB color space is directly represented; equivalent values are generated for other color spaces.

Histogram HSV - The HSV (Hue/Saturation/Value) Histogram shows the distribution of hue (which color appears most prominent) in the top row, the saturation level (how much gray in each particular color) in the center, and the value (luminance, or how light or dark the signal appears) in the bottom row.

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.

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. For details, click here.

Audio Meters - Up to 16 audio channel metering is supported. Meter types include dbFS, SMPTE RP-155, EBU R-68, Loudness (US or EBU), and PPM with EBU or BBC 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. A number of display modes can be set using the Display Mode selector:

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 low, or red anywhere the signal is too high.

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 and XDS Data 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. XDS (extended data service data) 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.
