videoQC - Automated and Visual Analysis Tools

DrasticPreview audio video metadata player logovideoQC is a video and audio analysis and playback tool 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 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 comes in four flavors, each designed to fill a particular part of the QC 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 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 a Decklink board is fully supported.  During playback, real time timecode is displayed along with audio meters in RMS or EBU r.128 levels.  Frame accurate seeking, by timecode 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 timecode is also available by using -c and -v

Closed Captioning

DrasticPreview 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 if you want to test this feature.

Track Info

All versions of videoQC include a basic track info display on the main display, and a more detailed track info pop up.  This 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.
