The is a battle between the material’s initial superior engineering and the inevitable degradation of time. While we cannot turn the brittle polyester back into a flexible ribbon, the techniques outlined above—humidification, archival taping, ultrasonic splicing, and climate control—offer a path to salvage these historic reels.
Diamant-Film is a professional video restoration software developed by Diamant International, a leading company in the field of film and video restoration. The software is designed to help professionals and enthusiasts restore and enhance old footage, removing defects, and improving image quality. Diamant-Film offers a wide range of features, including:
Best for Level 1 cracks where the base is still flexible.
While polyester base is generally resistant to shrinking and vinegar syndrome (which plagues acetate films), Diamant-film’s specific formulation introduced rigidity. Over 40 to 70 years, plasticizers leach out. The "diamond" hardness becomes brittleness. When humidity drops below 30% or temperatures fluctuate rapidly, the emulsion layer (gelatin) contracts at a different rate than the PET base. This differential stress manifests as the dreaded Diamant-film restoration crack —usually appearing as longitudinal lines parallel to the perforations or as spiderwebbing in the center of the frame.
