The actual digital insertion of actors was conducted in the same manner as seen in the 1994 film "Forrest Gump" (1994). The original footage was remastered, and was seen as such an improvement that it inspired the subsequent clean-up and re-release of all of "Original Series" episodes. This remaster was conducted by Hutzel and is the first transfer since 1983, when a version was created for VHS and laserdisc release. Hutzel identified 19 scenes from "The Trouble with Tribbles" which were matched in "Trials and Tribble-ations". The scene matching between the new footage and the old took nine weeks to complete with a budget of $3 million. It involved both two-dimensional and three-dimensional tracking shots as well as insertion of matte shots and the use of both blue and green screens for the actors. The scene where Sisko meets Kirk on the bridge toward the end of the episode was taken from the episode "".
