We are a highly skilled moving image conservation and restoration company, partly operating at the Lichtspiel in Bern, Switzerland. Our team provides worldwide comprehensive services that encompass the whole range of audio-visual preservation, offering Swiss quality at a competitive price. We publish a newsletter approximately once a month, summarising news relevant to the preservation of audio-visual media. We have a particular commitment to the dissemination of low-technology and low-energy audio-visual conservation and restoration techniques. We support open-source projects which we believe are beneficial for the archival community.

Our Services Include

research, training and consultancy on audio-visual preservation
film digitisation for both preservation and access purposes
digital moving image and sound restoration
files and data transformation
maintenance and migration of digital archives
