4kScope
Measure Everything
4kScope software provides a real time, professional quality signal analysis tool for on set, production, post production, and research and development environments. 4kScope is designed to monitor from 4096x2160 down to NTSC/PAL and everything in between. It support SDR and HDR image analysis with support for 601, 709, 2020, WCG, HDR10 and WCG colour spaces. Multiple audio and video scopes can be selected in a variety of layouts depending on your monitoring needs.
90 Seconds With 4kScope
Video waveform, audio waveform, rgb waveform with zoomed picture
View your color bars, test patterns, live camera or telecine signal for device or facility installation, setup, commissioning, certification and other operational reference. Confirm that the color gamut and analog transmission limits are not violated and that the color phase is accurate.
Version 5.0 of 4kScope provided zoom, safe zones, line/dot, line/area select and support for everything from SD to 4K 60p for AJA, Bluefish444 and Blackmagic video boards.
Version 6.0 adds multiple, simultaneous scopes as well as audio phase/waveform displays, chromaticity and running status pages.
Version 6.1 also supports 12 bit RGB and YCbCr/YUV 4:4:4 workflows so you can monitor and analyze HDR images from 12 bit capable software like Autodesk Flame, DaVinci Resolve, and Colorfront. Event logging, raw capture and remote, an HTML web based UI has also been added for remote monitoring and operation.
The Interface
There are fourteen main components to 4kScope:
Picture incuding view modes:
Red only, green only, blue only, luma only
Zebra luma, zebra chroma, clipping
Edge difference, focus assist, flip/flop
False colour
Vectorscope (with WCG support)
Waveform Luma (with HDR10 support)
Waveform RGB (with HDR10 support)
Waveform YCbCr (with HDR10 support)
Histogram RGB
Histogram Luma
Chromaticity
Status
Audio vectorscope
Audio waveform
Audio histogram
Audio phase
Event logging list (signal loss, change, gamut, etc)
and a separate data view.
The thirteen components can be laid out in five different layouts: single, side by side, one large/three small, four quadrants and six up (three across, two down). To the right of the scopes either 8 or 16 audio meters are displayed for loudness or peak/rms. Below the meters there is a status window that displays time code and user bits for the RP-188 V and RP-188 L SDI inputs and the analog SMPTE time code input if available. If closed captions are detected, their presence and type is also displayed.
4 scope large view (Histogram, Picture, Chromaticity, Waveform)
4 scope even view (Picture, Waveform RGB, Vectorscope, Waveform YCbCr)
Vector
Vectorscope
The Vectorscope displays a traditional Cb by Cr X-Y display with overlaid reference graticule. 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.
The exclusive Drastic Luma Stick (patent pending) displays luminance distribution and strength in a space saving and intuitive graphic format.
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).
Finally, a mini pic is always available as a confidence monitor.
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.
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 luma waveform supports standard, HDR10 (Dolby Vision/ST.2084) and HLG (Hybrid Log Gamma) display up to 10,000 nits. 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.
Waveform Luma in HDR10/HLG Nits display Mode
Critical for downstream color correction is the need to ensure proper luminance levels at the stage of initial capture, so any 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).
Finally, a mini pic is always available as a confidence monitor.
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.
The Luma waveform display allows for finer display of the luminance part of the video signal. This scope can be run in 8 bit or 10 bit mode and displays valid levels as well as out of bounds levels. The luma waveform supports standard, HDR10 (Dolby Vision/ST.2084) and HLG (Hybrid Log Gamma) display up to 10,000 nits. It also includes a mini pic when run alone, or can be run with any other combination of scopes.
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.
At all times a minimum and maximum value for each of the channels (R, G and B) is displayed in 10 bit mode (0-1023).
Finally, a mini pic is always available as a confidence monitor.
For dual link RGB signals, the original RGB 10 bit values are used unprocessed. For single link YCbCr signals, they are first converted to RGB before being analyzed and displayed.
The 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. This will delineate 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 over black, or black over white. The amount of a color will cause that dot to be scaled from the second color to the first.
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.
Finally, a mini pic is always available as a confidence monitor.
The Picture view shows the video signal, to confirm the source is correct and to display time code location. Both picture safe and title safe graticules are optionally available.
There is a scaled down version of the signal input on the right of each of the other scopes when they are run alone. They are a useful reference but smaller than the Picture view. This view exists to provide the fullest display of the signal for optimum quality viewing.
Data
The Data view allows access to the raw pixel values being monitored on the HDMI or SDI input. Values are captured and displayed in their raw values, with no manipulation by the software. Capture card ranging is maintained, supporting both 0..255 and 0..1023 (inclusive). For YCbCr signals, the Y/Cb and Y/Cr pairs are displayed next to each other with no interpolation. For dual link RGB, the 0..1023 components are also displayed directly. 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. Pixels can also be 'picked' by clicking on the video image to set both pixel and line start. Hanging the mouse over the picture, will pop up a tool tip with the R, G and B percentage as well as the pixel X and Y position.
Audio
Audio
4kScope includes a full set of audio tools. Up to 16 channels of audio are supported for metering. Embedded, AES/EBU and analog inputs are supported (depending on hardware), each with independent ppm/rms or loudness metering. R.128 EBU 9 and EBU 18 scales are available in addition to the RMS meters.
Audio Vectorscope
The audio vectorscope measures the difference between channels of a stereo pair. One channel drives the horizontal and the other the vertical deflection. This will show the relative phase of the two channels. This can be shown in Lissajous XY, Lissajous or Polar modes. Any pair may be selected in the setup.
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
The audio histogram displays a bar chart of the levels of the components of an audio signal. This can be displayed as linear or logarithmic. The scale can be set as linear, square root, cubed root, log or reverse log.
Audio Waveform
The audio waveform of any pair of channels can be displayed in real time as well.
4kScope supports 8 bit and 10 bit processing. 10 bit processing allows finer analysis of the signal, and even detection of 8 bit signals in a 10 bit path (note the missing lines/bins in the luma histogram on the right). Smooth scopes on true 10 bit signals (like the luma histogram on the right) display every possible level in the signal. An 8 bit processing mode is also available in 10 bit mode, to allow for mixed mode scopes.
Zoom and Zoom Pan
4kScope supports zooming 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. To zoom, place the mouse over the picture or scope, and roll the mouse wheel. To pan the picture, click on it and drag it until the area of interest is visible. To reset to normal zoom, right click the mouse.
Signal Compare
4kScope includes a signal compare feature that 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.
Closed Captions
4kScope supports decoding of closed captions from line 21 encoding (SD) and line 9 ANC encoding (HD). The SD 608, HD 708 and OP-47 can all be decoded in real time from the incoming signal. The actual data can also be viewed on line 9, or 21 for SD, in data mode. The captions can be selected for displaying over the video in 8, 10 or RGB 10 bit. Closed caption types that are detected are all displayed in the data area below the audio meters.
Remote Monitoring
4kScope can be controlled and viewed 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:
Timecode
4kScope reads multiple time code types simultaneously and displays them in the lower third data area. RP-188 VITC and LTC, SMPTE LTC (analogue), vertical blank encoded VITC and RP-215 film KLV time code are all supported.
Full Screen Mode
Double clicking on the 4kScope interface will put it 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.
Raw and JPG Image Capture
The incoming image can be captured as a raw (YUV, V210, RGB10) image in full, bit perfect images to your Pictures/4kScope/ directory by pressing <CTRL>-0. These can be read or converted with videoQC or MediaReactor. Using <CTRL>-1, a JPG image can be captured in 8 bit YCbCr mode for easy reading and documentation. 10% and 50% JPG scaled versions can also be captured with <CTR>-5 and <CTRL>-9.
Setup
Setup
Setup controls the overall configuration of the scopes and associated hardware.
Video Input selects 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.
Audio Input selects either 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.
Signal Format lists all the formats supported by the I/O hardware.
Color Format determines the processing mode. Single link: 8 or 10 bit YCbCr 4:2:2 or RGBA 8. 3G/6G/12G/Dual link YCbCr 4:4:4 10 or 12 bit, RGB 4:4:4 10 or 12 bit, RGBA 4:4:4:4 10 bit (hardware dependant)
4K/QHD Color For SD, HD and QHD/4K the color space can be 601, 709 or 2020 (WCG)
4K/QHD Transfer For HD, QHD and 4K, the transfer can be standard, standard 709 2.2 gamma, HDR10/ST2084/PQ/Dolby Vision or HLG (Hybrid Log Gamma).
Picture Mode determines how the conversion is done. All standard modes for up and down conversion are supported
Down Convert determines the output signal type. The output can match the input or be converted to another up or down signal format.
Output determines the analog output formats. In SD this can be Composite, S-video or Component. For HD, only Component is supported.
The Closed Caption source may be selected for display on output.
The Auto Follow Input checkbox when selected sets the system to change its file format parameters when the input changes.
The number of Audio Channels displayed in the meters may be set.
Audio Pairs lets the user choose which audio pair is used for stereo output monitoring.
