of filming on March 9 saw the movement of the shoot to the Dauntless engineering set. The design proposed by Kolbe did not make it into production due to the cost and complexity of it, but he was still pleased with the final result as it enabled some different shooting positions than the usual Voyager set. The engineering set did provide some challenges; a health and safety brief was required for the actors on it as it was still raised off the ground. Furthermore, the results of the bubbles being sent through water tubes that represented part of the engine core created noise issues for the sound technicians; they asked for it to be turned off whenever it wasn't placed in shot. One of the special effects went wrong, causing an actual explosion behind Jeri Ryan rather than simply creating sparks following the weapons fire which would be edited in during post-optical effects. The explosion remained in the final cut. The final day of the shoot took place on March 10; taking the filming period to eight days, a day longer than normal for Voyager episodes. It took place on the set of the Dauntless bridge, in the orange color scheme. The final full scene filmed was of the scene at the end of the episode where the Dauntless returns to Borg space and Arturis realises he is about to be assimilated, and after an hour of closeups for various scenes, the shoot ended at 12:50am on March 11. Editing began later that day, with the first rough cut completed on March 18. A version was screened on March 30 for Moore, Peter Lauritson, Dan Curry, J. P. Farrell and Dawn Velazquez to better inform the post-production optical effects which were under production at the time. Cast audio re-recording took place from April 9 onwards depending on the individual actor's availability, supervised by Velazquez. Composer Dennis McCarthy first saw a cut of the episode on April 21. He worked with Velazquez and music editor Gerry Sackman to develop some musical cues which could recur throughout the episode as well as working out what type of work will need to be completed. For example, although he couldn't see the visual effects at the time as they were not yet complete, Velazquez explained what they should look like. The deadline for the final cut, including the visual effects was April 30. All
