The next step of the Storysketch, even do it is not a pre-requisit, it´s the Storyboard, the idea of the Storyboard is to have a deeper aesthetic development, that´s why the template for Storyboard has a bigger frame size than the Storysketch template, now, the next step of the Storyboard is the Animatic, the animatic is a storyboard but played on a timeline, now, if you are making an animated film you will find the animatic template useful (for live-action is not that handy), the idea behind the animatic blank template, is to be able to draw outside the frame if you need to (because maybe a camera movement needs to or you are drawing in more detail, or you are drawing layers), the animatic template is also useful to develop the layout (animation layers, for example drraw the background and the subject on diferent frames of the template).

All of these temples of course are only useful for hand drawn frames, if you have a digital pen, you only have to make sure to set the canvas aspect ratio according to the film aspect ratio and be sure to use an image software that can manage layers, such as the Gimp.

This is an example of the differences of a Storysketch, a Storyboard, and an Animatic, and later the final animated animatic layers:

The Storyboard templates are on the same format as in the previous Storysketch post (double click before saving the file to get the full resolution):
