Reversing the playback direction of a layer
You can easily reverse a layer’s playback direction. When you do, all keyframes for all
properties on the selected layer also reverse position relative to the layer. The layer itself
maintains its original In and Out points relative to the composition.
Note: For best results, replace the layer with a composition having the same frame size as the
layer, and reverse the layer inside the composition. This is the most accurate way to reverse
footage. For more information on nesting compositions, see “Organizing a project using
nesting” on page 342.
To reverse a layer’s playback direction:
1 In a Timeline window, select the layer you want to reverse.
2 Press Ctrl+Alt+R (Windows) or Command+Option+R (Mac OS).
Note: You can also play a layer backward by typing a negative time-stretch value in the Time
Stretch dialog box.
To reverse the order of keyframes without reversing the layer’s playback direction,
select keyframes and choose Animation > Keyframe Assistant > Time-Reverse
Keyframes (see “Using the Time-Reverse Keyframes keyframe assistant” on page 224).
To reverse a layer’s playback direction without reversing the order of its keyframes, use
time-remapping to reverse the layer (see “About time-remapping” on page 226).
