The original version was shot on 35mm film, then post-produced to broadcast videotape. Starting with this episode, the entire series was remastered to high definition by finding the archived film segments, transferring and recutting it together in HD. Optical effects were also recomposited from film elements. In this episode a couple things were corrected from the original version: an odd dissolve from one scene to another in the holodeck scene was smoothed over; and while in the original, a scene showing an energy beam emitted from what would be known as the Captain's yacht was corrected and now emits from the phaser rings.
