videoQC - File/IP Quality Control
robust media player for consistent deliverables
View files and streams, with time code, closed captions, and metadata. Compare your media to a template or file, and perform full reference analysis. It's easy to make sure the content conforms to your specs with audio and video scopes, display modes, and CSV/SQLite, HTML, and PDF reports.
|Windows 7 or greater, macOS Version 10.14 Mojave and greater, CentOS/RedHat 7.4-7.8|
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.

Main Interface and Displays
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
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
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.
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.
File Trim And Export
videoQC supports trimming the current clip, or clip list, and exporting it to standard file formats including:
- MXF Sony XDCAM
- MXF DPP (AVCi)
- MXF HDF (XDCAM)
- MXF OP1a (DVHD, MPEG-2, h.264, AVCi, Uncompressed)
- MOV (DVHD, AVCi, ProRes, Uncompressed)
- MP4 (h.264/AVC1)
The export also allows for the closed captioning or audio files to be replaced during the creation of the new file.
Please note: The file clipping and export feature is only available when running under a temporary or permanent license, Inspect 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
When reviewing High Dynamic Range content, videoQC lets you check the MaxCLL and MaxFALL levels for HDR content delivery workflows.
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
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.
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.
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.
The parameters of the analysis can be customized, and the current setting is displayed.
Adjustable parameters include:
- Vertical Line Repitition: lines, frame duration
- Missing Lines: lines, frame duration
- Missing Edges: (example above) top, top maximum, top frame duration, bottom, bottom maximum, bottom frame duration, left, left maximum, left frame duration, right, right maximum, right frame duration
- Black and White: chroma maximum, frame duration
- Still Frames: limit, difference maximum, PSNR check Y (38.0), frame duration
- Broadcast Illegal: broadcast illegal, frame duration
- Over Saturation: maximum, frame duration
- Contrast Blacks: minimum, frame duration
- Gamut Over: maximum, frame duration
- Gamut Under: maximum, frame duration
- Loudness: LKFS (24.0)
- Silence: limit, frame duration
Once the analysis has completed, you can click a button to view the data.
You can export the results for later review.
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 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.
There are a wide variety of available comparison modes:
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:
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:
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:
