Retime media
Intro to retiming media in the Motion Timeline
Your motion graphics projects may require you to perform special timing tricks on media:
speeding up a clip, slowing it down, or playing it back at different speeds. There are
several ways to retime a clip:
Manipulate clip timing in the Timeline with the help of modifier keys. Indicators in the
Timeline help you visualize loops and other retiming conditions. See Retime media in the
Motion Timeline.
Adjust the Timing controls in the Properties Inspector to modify speed and playback
attributes of media clips. See Timing controls in Motion.
Apply a Retiming behavior designed for common retiming tasks, including hold frames,
strobing, looping, and so on. Take some time to look over the Retiming behaviors in the
Library before spending a lot of time in the Inspector creating your own custom retiming
from scratch. See Intro to Retiming behaviors in Motion.
Retime media in the Motion Timeline
You can modify the duration and playback speed of video tracks in the Timeline using the
retime pointer or loop pointer.
Speed and duration are interdependent; that is, if you increase a clip’s playback speed, its
duration decreases, and vice versa. For example, a 60-frame video clip played back at 30
frames per second takes two seconds to display its 60 frames. If its In point is frame 1, its
Out point is frame 60. Playing back the same clip at 15 frames per second would take twice
as long; the clip’s In point remains the same, but its Out point becomes 120.
Shorten the video clip’s duration and speed up its playback speed
1. In Motion, with the pointer positioned over the end of a video clip’s bar in the Timeline
track area (the clip’s Out point), press and hold the Option key.
The pointer turns into the retime pointer.
2. Continuing to press and hold the Option key, drag the Out point of the clip’s bar to
the left.
As you drag, the tooltip displays the clip’s speed and duration.
Note: The retime pointer is available only when the Time Remap pop-up menu is set to
Constant Speed in the Timing controls in Motion. When Time Remap is set to Variable
Speed, the retime pointer has no effect. You cannot retime images, effects, and other
nonvideo objects.
