 The actual digital insertion of actors was conducted in the same manner as seen in the film <unk> <unk> ( 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 was the first transfer since 1983 , when a version was created for VHS and laser disc 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 . Not all shots seen in the episode were actually taken from " The Trouble with Tribbles " . The scene where Sisko meets Kirk on the bridge towards the end of the episode was instead taken from the episode " Mirror , Mirror " .
