Rather than use all-around motion capture for the characters of their new Space Pirate Captain Harlock movie, it looks like Aramaki Shinji and team opted to use the technique just for lip sync.
This video from Cinema Today shows off the technique, in amongst a bunch of other, seemingly random clips and sizzle stuff.
Seeing lips divorced from the rest of the body like this, it does remind me that, actually, nobody seems to have separated the mouth movements in an animated movie and re-animated them when exporting a movie for dubbing. I’d have thought, maybe, Dreamworks would have tried it – seems like one of their ideas. I guess it doesn’t matter to them so much, not as long as the non-English speaking audiences keep coming in.
