"A Bug's Life" was the first home video release to be entirely created using a digital transfer. Every frame of animation was converted from the film's computer data, as opposed to the standard analog film-to-videotape transfer process. This allowed for the film's DVD release to retain its original 2.35:1 widescreen format. The DVD was released on April 20, 1999, alongside a VHS release which was presented in a standard 1.33:1 "fullscreen" format. The film's fullscreen transfer was performed by entirely "reframing" the film shot by shot; more than half of the film's footage was modified by Pixar animators to fit within the film's aspect ratio. Several characters and objects were moved closer together to avoid being cut out of frame. The film's VHS release was the best-selling VHS in the United Kingdom, with 1.76 million units sold by the end of the year. On August 1, 2000, these editions were rereleased on VHS and DVD under the Walt Disney Gold Classic Collection banner.
