When scanning film material that is in a delicate condition (shrunken, brittle or damaged), the ARRISCAN registration pin can be retracted. Mechanical pin registration, however, delivers the steadiest possible image, so a pinless scan usually requires some post-processing to improve image steadiness.
The ARRISCAN now presents an easy-to-use solution: an algorithm for on-the-fly stabilization that is implemented in the image processing pipeline. This Built-in Stabilization has been developed in close co-operation with the R&D team at HS-Art, famous for its DIAMANT-Film Restoration software.
There are many different types of material: black-and-white and color films, unique and non-standard formats, films on a cellulose-nitrate, cellulose-acetate or triacetate base. Both emulsion and film carrier are subject to degradation and are affected by different types of problems (torn or missing perforations, scratches, warping, shrinkage etc).
Depending on the storage conditions and age of archive film material, various degrees of shrinkage are common.
- Stabilization based on perforation position
- Part of the internal image processing, so scan output is already stabilized
- No loss of image quality in downsampling 3K / 6K files
- Perforation can be cropped before saving the image, reducing the amount of data
- Safety border added to the picture prevents cropping of unwanted shifts
- Stabilization histogram to visually control the correction process
- Free version of Dustbuster+ LT for QC and manual correction of images that were not automatically stabilized

For feature film scanning as well as in a wide range of commercials, film restoration and in digital dailies applications, more than 100 ARRISCANs are in use worldwide. Constant evolution since its introduction in 2004 has made the ARRISCAN the futureproof investment in film digitizing.
