NOA's unique quality assessment tool for intellectual validation and adjustment of video content designed to streamline and optimize your archive migration process.
As a highly versatile tool, QualityChecker has multiple possible applications – fully integrated into a NOA migration workflow or even as a standalone process. QualityChecker workstations are normally placed in separate rooms to provide optimal conditions for focused analysis of audio and video. Operators load QC tasks from the workflow engine's queue, process the task, then submit created metadata and forward files for further processing.
German technology. Calculating and presenting 100% exact values, frame-exact navigation and processing, excellent outputs.
The application provides a variety of tools, offering a holistic, thorough evaluation of every aspect of the loaded file.
Designed to enable technical annotation and splitting of full carrier-length recordings into content-based files - in a non-destructive way!
Quality assessment of digitization outputs, digitally born files, or files produced externally by a digitization service provider or 3rd-party content producer.
Support for additional data sources - ingest reports, 3rd party analysis tools or processors.
Transfer QC describes the process of confirming that no new errors have been introduced when migrating content from physical carriers to digital files. Electrical metadata in the form of ISR events and/or RF traces (100% no false positive events) is forwarded by NOA’s capture application FrameLector and presented to the user in a clear timeline view as well as a marker list.
Problematic areas can be identified within seconds, their content examined, and an informed decision can be made whether the capture attempt is within quality parameters for the archive or if it has to be re-done to achieve a better result. Multiple capture attempts can be compared in a time-code synced A/B comparison.
Facsimile and interpretation are the two ways of storing video files captured from carriers within an Archive Asset Management system. The “facsimile” is an unaltered 1:1 copy of the original content (recommended in a lossless codec), whereas the “interpretation” of the carrier’s content may have corrected video and audio levels, or even re-arranged audio tracks to arrive at a normalized file format - still keeping the initial shape of the content.

QualityChecker offers frame exact trimming and 1 to n segmentation (destructive / non destructive) as well as video level corrections based upon luma and chroma level traces in one glance. Content of audio channels may be annotated and then automatically rearranged and/or normalized based on a target profile. All changes may be applied immediately by NOA’s MediaButler when encoding to target format(s) and/or saved for later processing upon retrieval of the material from the archive.

In carrier-based archives that have grown over several decades, a diverse range of audio track allocations can be encountered. These variations often result from past production standards, individual choices, or external factors, such as the acquisition of third-party content. For example, one item might have the native language on the first stereo pair, the foreign language on the second, and music on the third, while another item could have the foreign language and music on the first two stereo pairs and the local language on the third track.
To achieve a uniform allocation of audio tracks throughout the archive, QualityChecker provides a user-friendly interface for annotating the current state of audio tracks. Later, during the transcoding of final files, MediaButler, NOA's encoding software, will compare the annotation with a desired audio track allocation and automatically shuffle the audio tracks if necessary.
Beyond rearranging tracks, additional adjustments to the audio signal, such as normalization in line with EBU R 128, converting stereo to mono or vice versa, and other modifications, can be applied during the transcoding process with MediaButler based on predefined settings.

QualityChecker, like all NOA solutions, is designed to run on commercial off-the-shelf (COTS) hardware and to operate seamlessly on standard Windows operating systems. This approach guarantees that the hardware underlying NOA's solutions is not only easily maintainable and accessible but also highly reliable, offering users peace of mind with its long-term stability and dependability.
For optimal operation, NOA provides:
As a client application, QualityChecker operates under a per-workstation licensing model. Within an industrial digitization facility, conducting a precise analysis of necessary work steps is crucial for determining the anticipated job throughput and the corresponding time requirements each day. This analysis enables the precise specification of the required number of workstations for the project, ensuring seamless operations and the elimination of production bottlenecks.
