Do you mean I should just use the layout poses as key drawings? I most certainly will because I think it would make more sense because it would be totally pointless and redundant to trace over the layout drawings with rough key drawings, since the layout drawings are already rough in the sense that they are sketched, just like the storyboards except smaller.
To me, the layout stage is essentially the glorified storyboard/animatic stage. I draw my storyboards in GIMP. I draw the shots and poses within them. The shot refers to change of camera placement, whereas the pose refers to the change in characters’ expressions and actions and/or camera movement, like panning and zooming. When I label my storyboards, I would write either, for example, “Shot 1-1” or " Shot 1, Pose 1". After that, I would export them as .jpg files due to the already crude but watchable quality. After that, I import them into Kdenlive to make an animatic. I would time the storyboards for each shot and pose, if any, in the length of frames or even seconds. I use the animatic and its storyboards as a guide and the layout stage, which is basically the glorified animatic/storyboards, as a map, even though a map is a visual guide. Unlike the storyboards/animatic stage, however, I would draw more poses in the layout stage to better define and control the acting, which is indeed directing. I make storyboards 1/4 the size of the layout drawings.
I go for full HD; 1920x1080, in the layout and of course the remainder of the animation process until the finished product. That would mean that 1920x1080 / 4 = 480x270 for the storyboards. I shoot for 480x272 because I want to make sure that the video aspect ratio is divisible by 4.
I export the storyboards, layout drawings, including the backgrounds, and rough animation drawings as .jpg files because they are, well, already poor but watchable images. For the clean-up animation drawings, painted cels, and painted backgrounds, I export them as .png because they are, well, much better quality images, which are excellent for the finished product.
Thanks for the reply again.
