"A Bug's Life" was released theatrically in the widescreen aspect ratio of 2.39:1. The full-screen version, found on the VHS & DVD, was digitally re-rendered shot by shot, moving characters and objects closer together where necessary, to reframe and fit them into the 1.33:1 TV screen, According to Pixar more than half the movie was recomputed after changes in the camera's field of view or movement.
Two versions of the film have been released, each one with different fake outtakes over the end credits. The version released before December 18th, 1999 features a set, and the one released after that date has another. This was done because Disney hoped it would encourage people to view the film a second time.
