Couple of things to clarify here:
1. I'm aware of what Hellena Taylor said Bayonetta 1 took, but Bayonetta 3 appears to have more dialogue and story for Bayonetta herself specifically, especially given that there's multiple versions of the character now, and we're assuming that Hellena was meant to voice them all. Furthermore, Taylor is also a member of SAG, and they
have a rate card for performers, which indicate that you earn a minimum of $450 per hour, and up to over $900 an hour if it involves voicing multiple characters. (This is why Sean Chiplock, who voiced Revali, Teba, and the Deku tree in BOTW
got paid approximately $2000-3000 for a relatively smaller amount of dialogue—because he was doing multiple voices.)
2. Taylor also says that the $4000 offer was made after she reached out to Kamiya personally, so whatever they were offering her prior to that was definitely a lowball. (Again, assuming that Hellena was originally meant to voice every incarnation of Bayo in the game. The missing piece of the puzzle is whether they originally only wanted her to voice one version of Bayo with much less on-screen time.)
3. Regarding calibration of equipment, I don't mean the VA has to calibrate the equipment themselves, but they do need to be present for the process. Actual recording doesn't begin until you've done a few trials prior to the start of each session, and for that you very much need to the voice actor present in the studio. There's definitely ways to do this effciently, such as doing a lot of the prep beforehand and having recording sessions go on for longer, but it does still add up over the course of several days/weeks/whatever.
My basic point was that it isn't simple as boiling it down to "if it's only a couple weeks, $4000 isn't bad." There's a reason bodies like SAG exist, and it's to make sure that people are fairly compensated for the amount of work they're required to do. Nobody's trying to call you out—it's simply a question of making sure that all the relevant information is cited when we make statements about someone's worth.
Also, to clarify, I'm not saying PG or Nintendo were/are in the wrong—far from it. For all we know, we're only getting one side of the story and a warped/partial version of events. But either way, it is important to make sure people have all the basic facts that we
do know available to them.
