videoQC Pro Player is the most capable video player/analyzer/comparison software for Windows, macOS and Linux.  videoQC supports almost every broadcast, scientific and post production file format, and can load one or two files for visual comparison.  videoQC can also support HD-SDI and HDMI output via your AJA, BlueFish444 or Blackmagic video boards.  videoQC supports zoom and pan, loudness and RMS meters, waveform, vectorscope, chromaticity, histogram, audio phase/wave/vector, and full 608/708/OP-47 closed caption decode and display. For full reference tests, 39 visual comparison modes are supported including seamless split, mirror, side by side, difference and A-B thresholding.  Files can also be analyzed for single ended audio/video, or for full reference using PSNR, SSIM or MS-SSIM.  These tables can be charted for quick seek access to the video file and exported as high resolution or proxy MP4 files along with CSV, XML, PDF or HTML reports.  The HTML can include the charts, tables and proxy files for online checking of both single and full reference files.

Main Interface and Displays

Real Time Playback with optional SDI/HDMI

videoQC is a full fledged player, capable of playing back almost any post production or broadcast file.  Playback to the desktop with the computer's audio, or to SDI/HDMI via AJA, BlueFish444 or Decklink hardware is fully supported.  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

Video playback in the application fully supports zooming and panning the video in still or playback.  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 not only displays the current time code location, but allows the user to 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 -c and -v

Closed Captioning

videoQC Pro supports 608/708 Closed Captions. 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 Closed Caption section below for more details.

Please note:  The CC feature is only available when running under a temporary or permanent license.  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.

Track Info

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.

Audio Routing

videoQC has a full 16 by 16 audio routing panel (available in most versions).  This allows audio signals to be routed or joined from any channel in the file to any channel on the output.

{tab Auto QC}

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

The metadata analysis analyzes 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 machine, 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.

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.

{tab Scopes}

videoQC has 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:

• Waveform (YCbCr and RGB)
• Vectorscope
• Histogram
• Chromaticity (601, 709, 2020)
• Real time status
• Audio vectorscope
• Audio phase meter
• Audio histogram
• Audio waveform display
• Safe zones (action, title, graphic, picture)

The scopes can be configured and adjusted at any time, and will remember their last settings with every run.

The video may also be displayed in hex or decimal at the pixel level:

{tab Compare}

videoQC also supports automated and visual QC of compressed files, either against other compressed files or uncompressed original files.  Currently videoQC Workstation can generate single ended analysis, as well as full reference PSNR, SSIM and MS-SSIM graphs.  For visual comparison, 39 different modes are supported, along with inverting, flipping, grid and full zoom/pan modifiers.
