In 1975, the event was renamed Summer Film School, and it began to grow. It was still intended only for members and lecturers of film clubs, having taken place in one organising cinema or film club. However, the public interest grew bigger and bigger. The programme consisted of the films purchased for film clubs, films from the Czechoslovak Film Institute or films from the KVIFF, archives or embassies. The Czechoslovak Film Institute produced educational materials, published a non-periodical newsletter, etc. Summer Film Schools started to be attended by filmmakers who could meet up with the passionate and enlightened audience there.
Summer Film School had to move several times over the years, mostly for technical and organisational reasons (cinema renovations, capacity, etc.). From Písek it moved to Hořovice, Uherské Hradiště, Strážnice, Světlá nad Sázavou, Trutnov, and finally, in 1992, it anchored in Uherské Hradiště (except for 1997, when it was moved to Jihlava due to floods).
