After the script was finished and approved, the animators storyboarded each scene and the dialogue was recorded before the two were merged into the animatic.
The layout drawings and storyboards are then spliced, along with the audio and an animatic is formed (not to be confused by its predecessor the leica reel).
Following the revisions, the voices for the episode are recorded and an animatic is compiled to get the timing of the episode down to the necessary 11 minutes.
As a result, the writers were forced to make revisions to the script without having completely reviewed the animatic; no writing was done during the strike.
