videoQC - Automated and Visual Video QC Tools

Verify your video media quality manually or automatically

videoQC is a suite of video and audio analysis and playback tools with both visual and automated quality checking tools. videoQC will take the media coming into your facility and perform a series of automated tests on video, audio and metadata values against a template, then analyze the audio and video. It includes metadata extraction, comparison and templating tools, intuitive charting of audio and video metrics, a full set of audio and video waveform/vectorscope/phase tools, db and PDF reporting, file to file visual comparison, and clipping and exporting tools. videoQC's automated server components can run headless (no interface) for analysis tools. Integration with Net-X-Code suite provides quality control for IP based workflows. Each level of videoQC is designed to fill a particular level of the Quality Control workflow, from intern to master QC operators and even back end servers. The standard database format allows seamless and instant sharing of analysis results. Hot folders allow automation, optimizing those in the QC workflow.

Real Time Playback with optional SDI/HDMI

videoQC provides a full featured media player, capable of playing back almost any post production or broadcast file. Play files in the GUI with the computer's audio, or to SDI/HDMI via AJA, Bluefish444 or Blackmagic hardware. During playback, time code is displayed in real time, along with audio meters in RMS or EBU r.128 levels. Frame accurate seeking, by time code or absolute position, along with stepping, off speed play and forward/reverse play are all available via keyboard, mouse or external controller.  Looping, palindrome and audio- or video- only playback are also available.

Zoom, Pan and Full Screen

vqc zoompan

Want to get a really good look at some details? Zoom and pan the video in pause or playback mode.

Using the scroll wheel of the mouse, the image can be zoomed out to cover a wider part of the screen, or zoomed in to closely check individual pixels. Left clicking and dragging will move the image to view different parts while zoomed in. Clicking the right mouse button will fill the application with video, and clicking the middle button will set the image to pixel for pixel (where every image pixel is exactly one screen pixel).  Zoom is available in windowed or full screen mode.  Changing the video background color is also available using <CTRL><SHIFT>-mouse wheel.

Time Code Display

timecode

A dedicated time code field displays the current time code location. The user may enter a known time code location within a selected clip, and press Enter to cue that frame. In Full Screen mode, an optional time code display may be overlaid. The user may select between available time code sources by clicking on the time code source field.  Copy and pasting of time code is also available by using <CTRL>+C and <CTRL>+V.

Closed Captioning

videoQC supports closed caption display. The closed caption information will be displayed over the video frame when enabled.  Supported sources include SMPTE 436, CEA-708, OP-47/RDD-08, CEA-608, MCC, AAF, SCC, STL, EBU, embedded and many other formats. See the CC section for more details.

Please note:  The CC feature is only available when running under a temporary or permanent license, Pro version and above.  Please contact Drastic for a license if you want to test this feature.

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.

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 (a second monitor is recommended). The following scopes are provided:

VectorScope_1080-min
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.
WaveFormYCbCr_HDR_1080-min
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.
WaveFormYCbCrLuma_HDR_1080-min
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.

WaveFormRGB_1080-min
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.
WaveFormRGBParade_1080-min
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.
Chromaticity_1080-min
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.
HistogramLuma_1080-min
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.
HistoYCbCr_1080-min
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.
HSScope_1080-min
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.
UIHexView_1080-min
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_1080-min
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.
