Pipelines will vary per production. In FanBoy and ChumChum's case, they are using CG and don't need to be so on-model and can afford to scribble out the boards as haphazardly as they want. In Venture Brothers case, they have a very small team and need to present the ideas, art, and composition as finely pressed as possible to pass on to the animators so that they can be more cemented with what they want to do when they finally move on to the animation phase with as much direction given in the art as possible.
Shit, sometimes their boards look like comic book pages, and that's the point.
>>90300927I jerk off other people's artwork at least twice a day, it's all a blur at this point.
