The 1983 release by Paragon Home Video was dubbed from the original Beta video master. The 1985 Paragon re-release has very slightly different packaging and was duplicated from a theatrical 35mm print which was blown up from Beta. In this version, the opening narration is omitted (replaced with bleeping computer sounds), the credits sequences are matted in the 35mm's 1.85:1 aspect ratio and the rest of the film has been kept in it's original aspect ratio of 1.33:1
