After graduation, she attended the University of Tartu where she studied economic geography and demography. At university, she met students Peep Puks, Paul-Eerik Rummo and Kulle Raig, who were all interested in filmmaking. Poopuu began experimenting with an 8 mm film camera and the group would spend time filming one another.

In 1969, Poopuu began work on the Madis Ojamaa directed music documentary Uksed as a production assistant. This would lead to a lengthy career in the film and television industry as a filmmaker, working on various productions as an actress, production assistant, production coordinator, production manager, producer, assistant director and director. From the early 1970s until 1996, she worked for Tallinnfilm in a number of positions. Afterward, she worked for Danish, Finnish, German and U.S. film production companies until 1998.
