“I think people are impressed by the animation and what it brings, up to a point where people think that we were shooting real actors and then doing some sort of treatment on top,” Mielgo said. “Something that’s very important is the freedom that keyframe animation gives you. You don’t have restrictions, so you can be more flexible and have more expressions in the characters. You can do that with other techniques, but there are limitations in human movement that aren’t that exaggerated. With keyframe, you may have an arm that’s in an impossible position, but it was better for the action.”
