Theres that, and from what ive seen there is a lot of opportunity to take advantage of creatives? Like, people praise Andy Serkis as this huge revolutionary of mo-cap acting, but there it's pretty niche circles that understand the animators contribute equally to the performance. Studios have more incentive to offer an extra $1million to secure a celebrity actor, rather than adding a couple of thousand dollars onto the contracts for the crew.
On paper, the wages seem decent enough. However, the cities that are the VFX/animation hubs for mainstream TV&Film (LA, NYC, Vancouver, etc) tend to have a pretty high living cost, so it kinda cuts into the wage, unless you are lucky enough to be able to freelance and work remotely. Typically revisions don't count toward quota, and your aren't paid extra if your quota keeps you in the studio for longer than 8 hours a day. Which is what the video I posted above was getting into. Films and TV have tight release schedules that are planned way in advance, so the deadlines have to be met. It's the most important part of the job. That's not limited to animators - animation/vfx is just a particularly gruelling part of production.
This can sometimes create a dynamic where senior staff are choosing the shots/projects that allow them to meet quota easily, and the middle staff suffer by picking up the brunt of what juniors can't do and what seniors don't want to do. That is, If you work at a place where the employees are particularly jaded. I haven't seen this myself, but I have heard this from others.
In the case of the Sonic movie, I don't see them pushing the release date back because I doubt they want to compete with Frozen 2, which is coming out later that month. Overhauling such a big thing like the design of the main character seems like a huge undertaking if the movie is due to release in less than 6 months. I'm not a motion capture expert though, so I can't say for sure myself. A friend of a friend of mine is on this project, and they said it shouldn't be too bad, but I've also read a bunch on the internet saying otherwise.
