All versions of videoQC show basic track info on the main display, and provide a more detailed track info pop up.  The track info includes the video parameters (width, height, bit depth, codec), the audio parameters (channels, bit size, frequency) and the basic metadata information (names, device names, aspect ratio, length, camera settings).  For the more advanced versions, a separate comparison metadata window is available, and is described under the Analysis tab.

MaxCLL and MaxFALL

vqc maxcll maxfall

When reviewing High Dynamic Range content, videoQC lets you check the MaxCLL and MaxFALL levels for HDR content delivery workflows.

Audio Levels

vqc audiosettings

In videoQC, 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.

Audio Meters Popup

audio meters

videoQC provides an independent set of audio meters, which is larger, and may be moved onto a second monitor so you can view videoQC in full screen mode in the first monitor.

Audio Routing

vqc audio routing

videoQC has a full 16 by 16 audio routing panel.  This allows audio signals to be routed or joined from any channel in the file to any channel on the output. Various audio routing configurations for typical workflows can be saved and recalled for later use.

Please note: Specific features mentioned above are only available when running under a temporary or permanent license. Please contact Drastic for a license to enable the full feature set for your demo.

videoQC includes two main areas of automated analysis: Metadata and Metric.

Metadata Analysis looks at the incoming file, and determines as many qualities as it can about it. This includes, but is not limited to, file container, channel type and number, frame rate, video height/width/codec/bit depth/aspect ratio/compression/color matrix, audio frequency/bit size/codec/channels/type, and embedded metadata like source/copyright/description/source device/camera settings/reel/take/scene/source/slate/comments. Any of these may be used to create a template to compare incoming files against. One or more templates may exist on a videoQC system, and they can be exported/imported and shared. As well as a go/no go return on this comparison, a visual table will highlight any differences between the file and the expected settings, for easy operator identification.

vqc auto metadata check min

Metric Analysis - videoQC can also generate a full set of video metrics.  These are stored in a SQLite database, so that other applications can access them, and do frame by frame checks including:

  • Video size, and frame type (I, P or B)
  • Luma, Chroma, Hue, Saturation Min, Max, High, Low, Average
  • Vertical line repetition
  • Broadcast legal
  • Optional PSNR or MS-SSIM charting when pre-compressed source is available
  • Audio loudness and RMS

The metric analysis can be manually or automatically started.

Export Results

You can export the results for later review.

vqc metricsexport

You can create a CSV, PDF, an XML, or an HTML document to have a look at the analysis in various MAM solutions. There is an option to create a proxy file from the original source or a portion thereof. Results can also be exported as markers to Adobe and Avid.


Full Reference Comparison

videoQC Workstation lets you load two files and compare them against each other for visual examination and measurement. When a compressed file is compared to its original, typically uncompressed source file, this is referred to as a full reference comparison.

You can visually confirm degradation, or other compression artifacts by playing the two files in various comparison modes to see any obvious differences. Here is an example of the 'mirror' comparison mode.

vqc compare mirror

There are a wide variety of available comparison modes:

A Minus B with Threshold
Anaglyph Amber-Blue
Anaglyph Green-Magenta
Anaglyph Red-Blue
Anaglyph Red-Cyan
Boxes With Size
Checkerboard 3D
Difference with Threshold Modifier
Dissolve with Mix
Grid (Available in all modes)
Interlaced Eyes
Onion Skin

Wipe - Lower Left
Wipe - Lower Right
Wipe - Right Center
Wipe - Slide Down
Wipe - Slide Left
Wipe - Slide Right
Wipe - Slide Up
Wipe - Top Center
Wipe - Upper Left
Wipe - Upper Right
Wipe - Vertical

From the compare dialog, the user can also launch PSNR (Peak Signal to Noise Ratio), SSIM (Structured Similarity Indexing Method), and MS-SSIM (Multi-Scale Structured Similarity Indexing Method) analyses. Here are the steps to perform this analysis:

Open videoQC and load the compressed file.

Open the QC Analysis window and click full reference.

Open the Compare window and click the Disabled checkbox to enable Comparison mode. The checkbox will then display Enabled.

Use the Orig File button to browse to and select the full resolution source file that was used to create the deliverable content.

As described above, there are a number of visual comparison modes where you can show the two files side by side, over under, boxes mixed by size, and so on. The mixes can be adjusted to suit your workflow. Optionally a guide, or various grids may be overlaid. Flip modes are also available.

To perform PSNR, SSIM, and/or MS-SSIM analyses, click the checkbox(es) at the bottom of the Compare window and press the Launch Analysis button.

This launches the MRAnalyze exe, which performs the analysis. A percentage of completion is displayed.

Once the analysis has finished, videoQC will populate the database with the analysis data. At this point the user will be able to click on the full reference button in the QC Analysis window, and see the data in an intuitive graphical display.

Here is an example of a completed analysis:

vqc psnr ssim msssim

videoQC Pro, videoQC Inspect, videoQC Workstation, and videoQC Server all feature a full set of scopes. They can be viewed as a single large scope, or up to 6 scopes at one time. The scopes open in a second window, so a second monitor would improve the viewing experience.

The following scopes are provided:

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. The parade waveform is shown here, 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 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 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 256/1024/4096 possible colors.
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 cameras 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 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 Polar - 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.
