Bird stuck to elaborate scene planning, such as detailed animatics, to make sure there were no budgetary concerns. The team initially worked with Macromedia's Director software, before switching to Adobe After Effects full-time. Bird was eager to use the then-nascent software, as it allowed for storyboard to contain indications of camera moves. The software became essential to that team—dubbed "Macro" early on—to help the studio grasp story reels for the film. These also allowed Bird to better understand what the film required from an editing perspective. In the end, he was proud of the way the film was developed, noting that "We could imagine the pace and the unfolding of our film accurately with a relatively small expenditure of resources." The group would gather in a screening room to view completed sequences, with Bird offering suggestions by drawing onto the screen with a marker. Lead animator Bazley suggested this led to a sense of camaraderie among the crew, who were unified in their mission to create a good film. Bird cited his favorite moment of the film's production as occurring in the editing room, when the crew gathered to test a sequence in which the Giant learns what a soul is. "People in the room were spontaneously crying. It was pivotal; there was an undeniable feeling that we were really tapping into something," he recalled.
