In March, 1995 Oskar Siebert, with his daughter Daniela and Mr. Ulrich Boin, founded their own artistic film group, with the name: videoAktiv Regensburg. (Oskar had been since 1986 an active filmmaker in the Regensburg Film and Video Amateurs and a member of BDFA.)

The new film group concentrated on producing short films with social-critical themes. These subjects were worked on and produced with groups from Regensburg schools.

Thanks to high artistic and cinematic standards as well as their topical subjects videoAktiv Regensburg and its artistic leader, writer, cameraman and director Oskar Siebert, became the first artistic and cultural group of the city of Regensburg to make an international breakthrough in the non-commercial cinema world.

By the end of 2008 Oskar and Daniela Siebert’s short films had taken part in more than 400 international non-commercial film and video festivals. The films have presented not only non-commercial cinematography, but also the cultural politics of the city of Regensburg. The Sieberts’ short films are known in Australia, Belgium, Britain, France, Guernsey, Italy, Ireland, Canada, Austria, Poland, Portugal, Russia, Switzerland, South Korea, Czechia and the USA.

For his strong commitment to culture Oskar Siebert was awarded in 1996 the Culture Award of the City of Regensburg.

For cross-border cooperation with filmmakers from the Czech Republic, Oskar and Daniela Siebert were given the "Bridge Building Prize 2009".
