I know you guys have seen it in YouTube videos, or even on television commercials, but mainly on YouTube gameplay videos; where, for example, PewDiePie is playing a FPS horror game, and he screams and the text is "AHHHHHHHH" where "H's" continuously follow each other until the next jump cut/sequence. Is that just keyframing? Or is it literally punching in the text precisely at certain frames?
