A flipbook turns a stack of still drawings into a rhythm. You do
not need elaborate characters to begin: one bouncing ball can teach key poses, spacing, timing and the pleasure of a
well-made loop.
FORM STUDY / FLIPBOOKSA STUDY IN FORM
Three things to learn
THE ESSENTIAL PRACTICE
◇
Plan the important poses
Draw the moments that explain the action before filling every page. For a bouncing ball, mark the highest point,
the approach to the floor, the contact and the rise. Keep the ground line fixed on each page and use a light guide for
the ball’s centre. If the shape squashes at contact, widen it so the apparent volume stays roughly consistent. A
simple circle without shading makes inconsistencies easy to spot. Number pages in the corner that will be bound,
leaving the drawing near the edge you will flip. Test the stack early instead of waiting until every frame is
finished.
◇
Spacing gives motion character
Equal distances between drawings suggest a steady speed. Closely spaced drawings create a slower movement; wider
gaps make the movement feel faster. A falling ball accelerates toward the ground, so its positions spread farther
apart during the descent. At the top of a bounce, several nearby positions make the turn feel gentle. Distinguish
spacing from timing: timing is how long an action takes, while spacing is where the object appears in each frame.
Change one of those choices at a time during practice. Lay several pages side by side to inspect the path before you
judge the motion by flipping.
◇
Build a loop that joins
For a seamless loop, the transition from the last frame to the first needs the same care as every other transition.
Avoid drawing an identical first and last pose unless you deliberately want a hold, because that can create a small
pause. Track the direction and speed of motion across the join. A ball that rises at the end should continue rising at
the beginning, or turn with a convincing slow point. Keep the registration marks aligned when binding your pages. A
clip makes revisions easier than permanent binding. Try the frame player at a slow speed to identify awkward spacing
before increasing the pace.
THE WORKING DESK
Play the bounce study
This twelve-frame loop follows a ball through one bounce.
Choose the playback speed, start or pause, and use Next frame to inspect the spacing. The frame count remains fixed,
so a higher frame rate shortens the loop. Inspect the highest and lowest positions to see where the spacing changes
most.
KEEP BESIDE YOUR WORK
A few useful notes.
Draw a twelve-frame test before a long sequence. A small complete loop teaches more than an unfinished stack
of elaborate pages.
Use the frame player to compare six and twelve frames per second. The drawing sequence
stays the same while duration changes.
A pause is a choice: repeat a pose when the audience needs time to read
an expression or anticipate an action.
Keep the ball’s centre path separate from its outline. Correct the path
first, then add squash, stretch and personality.
