The Vectorscope displays a traditional Cb by Cr X-Y display with overlaid reference graticule. Color accurate graticules automatically switch between SD and HD 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. At all times a minimum and maximum value for each of the channels (Y, Cr and Cb) is displayed in 10 bit mode (0-1023). The color of the text for each channel indicates the following: in range (green), out of range but legal (yellow) and illegal/sync values (red). For single link 8 and 10 bit YCbCr signals, there is no color processing involved. For dual link 4:4:4 RGB signals, the equivalent Cb and Cr are calculated to create the display.

Vectorscope Detail
The minimum and maximum value for each of the channels (Y, Cr and Cb) is displayed in 10 bit mode (0-1023).
Minimum and Maximum values The color of the text for each channel indicates the following: in range (green), out of range but legal (yellow) and illegal/sync values (red). For each of the hues (Red, magenta, Yellow, Green, Cyan and Blue) the outer rectangle with the cross in it represents the 2 100% Marks 100% marker. When the 100% Marks checkbox is selected (checked), it is displayed. Clicking to deselect this checkbox removes it from being displayed. For each of the hues (Red, magenta, Yellow, Green, Cyan and Blue) the inner rectangle with the cross in it represents the 3 75 % Marks 75% marker. When the 75% Marks checkbox is selected (checked), it is displayed. Clicking to deselect this checkbox removes it from being displayed. An angled line just to the left of the Angle Marker for the red 4 Skin Tone Line hue (between red and yellow) represents the skin tone line.

Zooming in to an area of the image which features human skin allows the user to see how close it is to a typical human flesh tone, and possibly to adjust the file or signal to compensate for any deviance.

Drastic Luma Stick
The human eye is extremely sensitive to variances in this portion of the spectrum, and a well adjusted skin hue is required for accurate color grading on a signal or image. As well, the flesh tone is not race-specific. The Trace is the bright green bit that is drawn under the graticule by the actual signal. The intensity of the trace may be adjusted by using the Intensity slider. There are four angle markers roughly corresponding to 45, 135, 225 and 315 degrees. When the Angle Marker checkbox is selected (checked), it is displayed. Clicking to deselect this checkbox removes it from being displayed. The Drastic Luma Stick displays the luminance distribution and strength within the signal or image. When the Luma Stick checkbox is selected (checked), it is displayed. Clicking to deselect this checkbox removes it from being displayed.

YCbCr Waveform View
The YCbCr Waveform Monitor 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 Cb and Cr display the +/- 512 levels of chroma of both types. This provides a visual representation of the chroma range of the signal. 1
Critical for downstream color correction is the need to ensure YCbCr Waveform proper luminance levels at the stage of initial capture, so any monitor corrections will not muddy or wash out the signal information. At all times a minimum and maximum value for each of the channels (Y, Cr and Cb) is displayed in 10 bit mode (0-1023). The color of the text for each channel indicates the following: in range (green), out of range but legal (yellow) and illegal/sync values (red).

The histogram view shows the distribution of red, green and blue 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 1024 possible colors. These totals are then auto ranged to fit within the graticule and represent the relationship between the shades of each color and between each other. Each color has its own graph. The color's levels are represented from left to right, with the absolute left being 0 and the absolute right being 1024. The scale is presented as a percentage to allow for extremely bright or dark pictures to be analyzed without truncating.

The Video Input pulldown menu allows the user to select between the HD-SDI, HDMI or analog inputs. In the case of dual link, 2 inputs are used. In the case of quad HD (3840 x 2160) and 4K (4096 x 2160), all four I/O ports of the 3D are in use, so the downconvert is HDMI and analog only. The Audio Input pulldown menu allows the user to select between the embedded audio tracks (HD-SDI or HDMI depending on input), or the AES/EBU audio inputs. On some hardware, analog audio inputs are also available. The Signal Format pulldown menu displays the current setting, and allows the user to select between the formats supported by the I/O hardware. The Color Space pulldown menu allows the user to select the processing mode. In the case of single link, this can be 8 or 10 bit YCbCr or RGBA 8. For dual link it is normally YCbCr 10 or RGB 10. The Picture Mode pulldown menu allows the user to select how the conversion is done. All standard modes for up and down conversion are supported The Down Convert pulldown menu allows the user to select the output signal type. The output can match the input or be converted to another up or down signal format.

When the Auto Follow Input checkbox is selected, whenever the input type is changed, the settings for 4KScope are changed as well. When unselected, the settings will not change regardless of the input type. In systems that support 16 channel audio, the user would be able to select between 8 and 16 channel audio. Otherwise, only the 8 channel button would appear. The Audio Pairs buttons allow the user to select the audio pair that will be monitored. Once the system is correctly set up, pressing the Done button closes the Setup window.

Operations 4KScope can be used to view an input signal through supported AJA, Bluefish444 and Blackmagic video hardware. Once a capable system has been equipped with an install of 4KScope, the user may connect a signal to the appropriate inputs and begin to use the software. Multiple inputs may be connected to a switcher to compare and adjust any mismatched parameters of setup. To set up the system for the signal being monitored, press the Setup button. The Setup window will open, and the user can adjust various parameters of operation for effective operation. See the previous Setup section for details.
Zoom and Pan Zoom the waveform monitors and vectorscope 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. Zoom In or Out - To zoom, place the mouse over the picture or scope, and roll the mouse wheel. Forward zooms in, and back zooms out. Pan the Image - To pan the picture, click on it and drag it until the area of interest is visible.
