I thought it might be. I may go back sometime and do a corrected version of this where instead of recreating the splices (and covering one up as I did here), I just leave a gap in the audio. For some reason that approach didn’t occur to me while I was making this.
Also, I suspect a couple other cuts might be splices, except that I could also see them being intentional edits - cutting out the sign outside the emergency headquarters in that shot of the ruins of Tokyo, for instance, since most of the US audience wouldn’t be able to read it anyway.
The only actual cuts in the AIP version are the aforementioned defense headquarters shot, and the Minya instances.
The AIP version also has frames that are missing in the current Japanese sources like Sea Monster and SoG (e.g. the shot of Kenji Sahara’s character and the end of reel 1).
