QUADRIGA•Film Examiner
Within a large film collection QUADRIGA•Film Examiner allows to identify the adequate preparation and scanning procedure for each archival film reel - based on their physical and photochemical condition. By utilizing the latest MWA spinner film scanner the examination procedure is extremely gentle to the fragile film substrate, so that typically the archive film can be examined without mechanical preparation or cleaning. A stabilized HD proxy file and a precise inspection report is generated on the fly to support a content-based triage process.

The Challenge
The prioritisation of archival film safeguarding based on the understanding of the physical and photochemical condition is an extreme labour- & cost intensive triage process. This has prevented mass digitisation of large film collections so far.
The Solution
A new intelligent software-driven film diagnostic system with already built in film inspection expertise. Highly automated examination procedure.
Results
QUADRIGA•Film Examiner automatically provides a detailed inspection report with precise measurements of the physical and photochemical film properties together with an HD video proxy file for effortless film content triage.

Measurements and Inspection Report
QUADRIGA•Film Examiner supports multiple measurement with laser and visual sensors including the new patent pending V-Black diagnostic sensor using a proprietary illumination technique. The V-Black diagnostic sensor completely separates the surface and carrier imperfections from the image content on the emulsion as well as on the base side. QUADRIGA combines digital image analysis and the analysis of the special sensor measurement data. This way the examination process works fully automatic. QUADRIGA’s Inspection Report documents precisely scratches, splice condition, notches, D-min, D-max, shrinkage profile…
QUADRIGA QC View
QUADRIGA QC View report contains
Measures and documents amount of:
- Surface Dirt/Damage
- Emulsion Damage
- Line Scratch
- Shrinkage
- Perforation Damage
- Condition of bad splices
Counts the occurrence of:
- Number of bad splices
- Total number of frames
- Total film length with shrinkage
- Total film length without shrinkage
- Picture instability
- Number of shots
QUADRIGA QC View provides a frame accurate time series view of measures. Most important mechanical and photochemical film defects are automatically collected together with measures of imperfection on the optical scanning process read-out. Top defects are also visually highlighted in the QUADRIGA Inspection Report.

For the economical digitization of large film stocks, it is essential to have first a measure of the objective picture resolution on each of the archival film rolls in order to select an adequate film scanning procedure. But also to determine the correct digital storage requirements.
