Time-remap a layer
You can time-remap all or part of a layer
to create many different results, such as freeze-frame or slow-motion
results. (See About time-remapping.)
Freeze the first frame without changing the speed- In a Composition or Timeline
panel, select the layer that you want to remap.
- Choose Layer > Time >
Enable Time Remapping.
This command adds two Time Remap keyframes by default,
one at the beginning of the layer and one at the end.
- Move the current-time indicator to where you want the
movie to begin.
- Click the Time Remap property name to select the start
and end keyframes.
- Drag the first keyframe to the current-time indicator,
which moves the start and end keyframes. (If you are working in
the Graph Editor, drag the bounding box—not the keyframe or a handle—so
that both keyframes move.)
Freeze a frame in the middle of the duration of a layer- In a Composition or Timeline panel,
select the layer that you want to remap.
- Choose Layer > Time > Enable
Time Remapping.
This command adds two Time Remap keyframes by default,
one at the beginning of the layer and one at the end.
- Move the current-time indicator to the frame that you
want to freeze, and set a Time Remap keyframe at the current time
by clicking the keyframe navigator diamond for the Time Remap property.
- Select the last two Time Remap keyframes (the second
and third keyframes) and drag them to the right.
- Press F2 to deselect the keyframes, and then click the
second (middle) keyframe to select it.
- Press Ctrl+C (Windows) or Command+C (Mac OS) to copy
the keyframe.
- Press Ctrl+V (Windows) or Command+V (Mac OS) to paste
the keyframe at the current time. You should not have moved the
current-time indicator since step 3.
- (Optional) To extend the layer so that its duration is
increased to accommodate the time added by the freeze-frame operation,
press the K key twice to move the current-time indicator to the
last Time Remap keyframe, and press Alt+] (Windows) or Option+]
(Mac OS).
The portion of the layer between the first and second
keyframes plays at an unaltered rate (the same as for the non-time-remapped
layer), as does the portion of the layer between the third and fourth
keyframes. The second and third keyframes are identical, so a single
frozen frame plays during the time between those two keyframes.
Remap time using the Graph Editor To switch between Graph
Editor mode and layer bar mode, press Shift+F3.
- In
a Composition or Timeline panel, select the layer you want to remap.
- Choose Layer > Time > Enable
Time Remapping.
- In the Timeline panel, click the name of the Time Remap
property to select it.
- Move the current-time indicator to the time at which
to add a keyframe, and click the keyframe button
in the
keyframe navigator to add a keyframe.
- In the Graph Editor, drag the keyframe marker up or down,
watching the Time Remap value as you drag. To snap to other keyframes,
Shift-drag.
 Dragging the keyframe down slows down the layer. To slow the layer down, drag the keyframe
down. (If the layer is playing in reverse, drag up.)
To speed the layer up, drag the keyframe up. (If
the layer is playing in reverse, drag down.)
To play frames backward, drag the keyframe down
to a value below the previous keyframe value.
To play frames forward, drag the keyframe up to
a value above the previous keyframe value.
To freeze the previous keyframe, drag the current
keyframe marker to a value equal to the previous keyframe value
so that the graph line is flat. Another method is to select the
keyframe and choose Animation > Toggle Hold Keyframe,
and then add another keyframe where you want the motion to start again.
 Before you move a time-remap keyframe,
it’s a good idea to select all subsequent time-remap keyframes in
the layer first. This selection will preserve the timing of the rest
of the layer when you remap time for the current keyframe.
Remap time in a Layer panel- Open
the Layer panel for the layer you want to remap.
- Choose Layer > Time > Enable
Time Remapping. A second time ruler appears in the Layer panel above
the default time ruler and the navigator bar.
- On the lower time ruler, move the current-time indicator
to the first frame where you want the change to occur.
- On the upper time ruler, the remap-time marker indicates
the frame currently mapped to the time indicated on the
lower time ruler. To display a different frame at the time indicated
on the lower time ruler, move the remap-time marker accordingly.
 Drag the remap-time marker to replace the frame at the current
time marker.
- Move the current-time indicator on the lower time ruler
to the last frame where you want change to occur.
- Move the remap-time marker on the upper time ruler to
the frame you want to display at the time indicated on the lower
time ruler:
To move the preceding portion of the layer
forward, set the remap-time marker to a later time than the current-time
indicator.
To move the preceding portion of the layer backward,
set the remap-time marker to an earlier time than the current-time
indicator.
To freeze a frame, set the remap-time marker to
the frame you want frozen. Then, move the current-time indicator
(lower ruler) to the last point in time where the frame will appear
frozen and move the remap-time marker again to the frame you want
frozen.
