If you look back at the video in post No. 162, you will see the character, Nelson, glancing quickly right and left before going into his cringe. This was done with the use of smear drawings, which I have mentioned before. Chuck Jones The Dover Boys makes use of this technique extensively for quick transitions, so if you have this cartoon on DVD or can find it on You Tube, take a look.
Here is how they are supposed to work, based on a supposition that the frame speed is 24 frames per second.
You create your starting pose, A...
... and your ending pose, B.
Then you do this weird inbetween drawing that will appear on one frame only; this is very important.
If the movement is left to right, you trace the left contour of drawing A, then the right contour of drawing B.
Between those contours you handle the shape like a piece of taffy stretched across between the starting and ending contours.
As appropriate, include an arc of movement in this drawing.
The result will be a smear or blur that can be a quite effective transition. The viewer will not be able to focus on the inbetween but the effect will be of a smooth, although lightning fast, movement, rather like that of a bird suddenly moving its head.
This will work fine in black and white, but it works even better in full color.
Colors actually track better than lines. Here I have limited myself to just two colors, but more could also work. But more than 3 or 4 colors will not make the effect any better, and it is a lot of unnecessary work. They say that light colors track better than dark ones.
Let's now look at a video of this effect, created in Flipbook through Autodesk Sketchbook.
Note: For the best effect, try looping this video. See instructions at the top right of this page if you don't already know how.
When you loop the video, you will see that this effect--having no anticipation nor drag nor follow-through--works just as well backwards as forwards. I hope you enjoy using this fun effect!
