In 1995, Weigert founded the company Dreamscape Imagery Inc. with his wife Stacey. He became VFX Project Manager for the film "Independence Day" (1996), for which Weigert created "Digital Assistant for Visual Effects", a project management software to manage, schedule and track the filming of VFX elements. In conjunction with the software, Weigert also developed a design for a visual effects production board, in conjunction with manufacturing company Hollywood Production Boards. Between 1996 and 2000, he created new software versions to include the post-production process. Digital Assistant for Visual Effects has been used for several feature films, including "Stuart Little", "Alien Resurrection", "Flubber", "Volcano", "Godzilla", "Wing Commander", "Monkeybone", "Bless the Child" and "X-Men", as well as on television films and series. Dreamscape Imagery Inc. sold the source code to the Internet company Creative Planet Inc. in 2000.
