Note: For information on creating a freeze frame, see “
Creating a Freeze or Hold Frame”
on page 300.
Reverse: Reverses the playback of video objects.
Crop: A multidimensional parameter that defines a number of pixels to be cropped
from each of an object’s four sides, relative to the outer edge of the bounding box that
surrounds that object. Cropping an object in the Media tab also crops all instances of
that object that appear in your project. A similar Crop parameter appearing for objects
in the Layers tab allows you to individually crop each instance of that object. For more
information, see “
Parameters in the Properties Tab” on page 241.
Timing: The Timing parameters define an object’s duration, including the start and
end points relative to the clip’s media file on disk, and its total duration in frames.
Adjusting these parameters for an object in the Media tab defines the maximum
duration available to each instance of that object in your project, limiting how much of
that clip is available for use in the Timeline. This can be useful for trimming off frames
that you know you never want to use to avoid accidentally trimming them back in.
Also, trimming a clip here changes the effect that setting an End Condition has on a
clip. Similar timing parameters for each instance of that object in the Layers tab allow
you to individually set the duration and In and Out points of each instance of that
object that appears in the Timeline.
• Start: Defines the starting frame of that object relative to the first frame of its media
file on disk.
• End: Defines the ending frame of that object relative to the last frame of its media
file on disk.
• Duration: Defines the total number of frames used by that object, as modified by
the start and end points. Adjusting this value also changes the End parameter.
Linked Objects: This list displays all objects that appear in the Layers tab that have a
relationship to that object. Two columns display the name of each layer containing an
instance of the source media, along with the object’s name. Changing an object’s name
in the Layers tab automatically updates the name that appears in the corresponding
object’s Linked Objects list.
Replace Media File button: This button allows you to relink an object in your project
to another source file on disk. This feature is primarily useful for relinking offline
objects, but it can also be used to substitute the media used by an object in your
project with other media. It also lets you replace one object with another, along with
all instances of that object in your project.
Summary: A separate pane that lists the properties of the media file on disk that’s
linked to the selected object.
