Although I am now a believer in serious thumbnail planning, I admit that I have always had difficulty judging the timing of an animation with only key drawings to work with in the pencil test. Suppose you have a character throwing a ball. You make a drawing each for the starting pose, the anticipation, the pitch, the recovery and the ending pose. In the pencil test you expose each drawing for its own duration, plus that of all the anticipated drawings between it and the next pose. Thus, if you have decided that drawing 1 is an 8 frame hold and then there are 8 more frames of movement until you get to drawing 2, you will expose drawing one for 16 frames. I can imagine this in my head and time out the spacing with a stopwatch, but to string the 5 drawings together in a pencil test and try to decide from that whether it is going to work, is hard for me. Still, in my time I have done a lot of animation where I did not give the poses enough time to "read", so I am going to work with this a while and maybe I will get it.
Here is a pencil test using the same thumbnails as shown in Part 2.
This pencil test omits the first of the seven poses,
and you can see that it was done on the upper edges
of the original drawings.
I think now the poses do read, and so I feel I can proceed to full-size animation drawing now and add more nuance. Here is the first test with all inbetweens present:
Here is the new test, now with 21 drawings:
Alright, this all seems to be working well. One of the new drawings was a single exposure of the kickout, a hyper exagerrated drawing with no drawings between it and the previous extreme. Everything else here is on 2's. Here is that drawing in blue and the one following in orange:
