Ebba Sinzinger, an Austrian, studied at Allegheny College in Meadville, USA, the University of Vienna and the University of Applied Arts in Vienna, from which she graduated with a master's degree. She subsequently worked as a curator and organizer of film and video festivals and as a film critic. She gained practical film experience by assisting in New York and Rome. In 1991 she began working as a freelance documentary filmmaker. Her films include "Chargaff" (AT 1997), about the world-famous biochemist Erwin Chargaff, and "Daydream Nation" (AT 1999, together with Vincent Lucassen), which places the everyday life of garbage men in worldwide metropolises in the context of social and urban developments.

In 2004 she began working as a producer at Wildart Film in Vienna. A great success was "PianoMania" (DE/AT 2009), which she co-produced, about the collaboration of a concert pianist and a grand piano tuner. The film was shown at numerous festivals and won many awards, such as the German Film Award for Best Sound Design. With the documentary "Im Jahr des Hasen" (AT 2010), about an adopted son from Cambodia who traces his origins, Sinzinger realized another film of her own.

Among others, she was a producer on the documentaries "Michael Haneke – Liebe zum Kino" ("Michael H. Profession: Director", AT/FR 2013) and "Brüder der Nacht" ("Brothers of the Night", AT 2016), about four young Roma who have to sell their bodies in Vienna in search of freedom and quick money. In parallel, in 2014 Sinzinger began working with Monica Lazurean-Gorgan and Michaela Kirst on the documentary feature "Wood - Der geraubte Wald" (AT/DE/RU), about illegal logging, the machinations of the global timber mafia and a group of people who take action against it. The film was completed in 2020 and screened at numerous festivals, such as CPH:DOX in Copenhagen and Diagonale in Graz. The German theatrical release was in December 2021.
