The project took three years to complete using existing English-language soundtrack material previously released on VHS and DVD by Kidmark and Voyager Home Entertainment. The original Japanese audio was used for restoration of selected scenes where English-language dialog was not present or not an issue. I presume that video source material for the project came from the digitally remastered Space Cruiser Yamato DVD box set released in Japan.
In Japan, the original 35mm master negatives were digitally revived and restored in consultation with Space Cruiser Yamato co-creator Yoshinobu Nishizaki to create the Space Cruiser Yamato DVD box set. I understand that the digital restoration process also faithfully reproduces all foreign objects that were also present on the animation stand when the cels were filmed. Dirt, cigarette ashes, hair, and dandruff all leap off the screen in razor sharpness.
