QScan 3.6 - available now - adds a raft of new features to the comprehensive list of video checks. This is our third major release of 2019 and we have more additionals to add shortly!
Deliverable requirements are different in different geo-locations. But how do you check if the same content is being delivered in a myriad of different codecs, meeting strict delivery specifications? QScan Comparative Analysis is a-first-of its-kind solution in the Automated QC space. While other solutions only analyze single files in isolation, QScan Comparative Analysis shows the relationship between up to ten different revisions of the same file and can show these differences along a timeline view for even easier review; clients can review multiple different QC deliverables and compare side by side.
The business benefits of QScan Comparative Analysis are quickly realized. By providing context around the changes made to a file after testing, creatives are able to minimize the time spent confirming that the file is ready for delivery. At a glance, users can see what changes were made to the file compared to the original; the timeline view gives additional context on when changes were made. With ever-tightening deadlines, QScan Comparative Analysis helps creatives hand off multiple deliverables of the same final project with confidence, increasing output and efficiency.
QScan is now making it easier and quicker than ever to analyze all your digital files. The new Quick Analysis option enables the user to start an analysis just by selecting a pre-designed template, and selecting a file (or multiple files). There's no longer a need to first create a new project, although that option still exists.
Once the user selects a template and file(s), a new "Quick Analysis project" will be created. The project will take its name from the selected template.
For many years home viewing television audiences have been frustrated by the loudness of commercials. The CALM Act requires that the US Federal Communications Commission (FCC) enforce that network and cable providers broadcast no commercials louder than the programming before or after it. Similarly in Europe, EBU R 128 is a guideline for loudness normalization and permitted maximum level of audio signals.
Whilst QScan has always provided Loudness checking, with 3.6 the user will now be able to select an offset for loudness measurements. This enables irregular sections of a file, such as test tones, to be skipped to ensure correct baseline readings. The offset must be entered in either hh:mm:ss:ff / hh:mm:ss:msec formats. The loudness will only be measured from the startTC+offset until the end of the file.
Mean Audio Phase:
Audio waveforms are cyclical; that is, they proceed through regular cycles or repetitions. Phase is defined as how far along its cycle a given waveform is. The measurement of phase is given in degrees, with 360 degrees being one complete cycle. Problems can occur when mixing together two waveforms, as waves that are in phase add to produce a sound wave of greater amplitude. The new Mean Audio Phase feature will find the average of the audio phase across the whole file. It will provide just one value per channel. The user can select what channels to compare when adding the threshold.
Support for EXR and TIFF sequences:
Open EXR an open-source high-dynamic-range imaging image file format created by the Industrial Light & Magic visual effects company.
EXR files are used by various photo editing applications, but mainly used for visual effects and animation programs because they can store high-quality images multi-depth, can be comprised of lossless or lossy compression, support multiple layers, and hold a high luminance range and colour. QScan's latest release includes support for Open EXR, enabling VFX facilities to check the legality within their files.
Storage of reports in a user defined location:
PDF reports can now be saved automatically to a location defined by the user. Note: only locations accessible as repositories.
DCP package identification and correct display:
A DCP (Digital Cinema Package) is a collection of digital files used to store and convey digital cinema audio, image, and data streams. A lot of studios deliver their films to local theaters through this form and is widely accepted as the replacement to film. New in 3.6, DCPs will now be displayed in a ‘tree’ chart view similar to IMF packages, enabling facilities to better see the schematic layout of the DCP.
Dolby Vision HDR analysis from Sidecars XML files:
Dolby Vision HDR workflows are now fully supported. With the latest release, instead of having to embed HDR information in the video file, QScan now has the capability to read sidecar XML files. During the workflow, the video file and the sidecar XML both go through all production stages and HDR data is only embedded upon final delivery of the Dolby Vision file in J2K. This process simply requires the sidecar XML and video file to have the same name.
Easy configuration of EditShare Media Spaces:
We are all about improving workflow every step of the way and are making it easier for EditShare users. Media Spaces can be configured easily from QScan now. The user will need to enter the IP and credentials for the host machine for EFS Media Spaces, and then select the desired Media Space or project space when configuring the network share.
Configuration for Editshare Media Spaces authentication.

Improved Video Bitrate computed correctly:
The video bitrate is enhanced over previous revisions of QScan, improving the ability to compare video bitrate thresholds with the overall bitrate. The final conclusion of a bitrate should provide valid and accurate results.
