24
frames
of
film
makes
up
one
second
on
the
motion
picture
screen;
an
easy
way
to
remember
this
frame
rate
is
there
are
24
hours
in
a
day.
Always
remember
24
FPS
(frames
per
second)
when
you're
animating
on
film,
it
is
an
unchanging
constant
for
which
all
animation
calculations
for
film
in
the
United
States
are
based
(Europe
has
their
own
25
FPS
mantra).
Video
and
most
computer
animation
packages
run
at
30
FPS
but
that's
another
mantra
entirely.
