move the points.
Thus, you can
create an effect
where a clip will
begin in slow
motion, speed up
and then slow
down again at the end of the clip. The plotting of keyframes is
reflected in the graph in the Motion tab.
You can also move the keyframe points within the Motion window. Make sure
you have selected the Time Remap tool and simply grab hold of the
keyframes and move them. Keep an eye on the increments in the Timeline
beneath the clip and observe whether they contract or expand. Remember,
spread apart will create slow motion, whereas increments close together will
create fast motion.
If you want a clip to play forward
then into reverse you need to
plot the keyframes so that the
angle within the graphical
display in the Motion tab is
straight up and down.
A line climbing at an angle vertically indicates forwards motion, while a line
heading downhill is for reverse. You can therefore set a clip to move forwards,
backwards and forwards with each move effectively ramping time into slow or
fast motion.
One final tip: if you control click on any
of the keyframes in the Motion tab you
will get an option to clear a keyframe or
make it smooth. Select the smooth option
and play back the result. You can perform
Time Remapping functions at keyframe
points which are smooth and fluid. This is a
