When a PDF is selected in the Media list, these controls set the maximum resolution to which
a PDF object can be smoothly scaled. For more information, see
PDF files on page 171.
•
Crop: Click the disclosure triangle to reveal four sliders that define the number of pixels to
be cropped from each of the source media’s four sides, relative to the outer edge of the
bounding box that surrounds that source media. Cropping an item in the Media list also
crops all instances of that item in layers of the project. A similar Crop parameter appears in
the Properties Inspector when you select a layer in the Layers list. For more information, see
Parameters in the Properties Inspector on page 223.
•
Timing: Use these value sliders to set the start, end, and duration of the source media:
•
Start: Sets the In point of the source media, in constant and variable speed modes. Adjusting
this parameter moves the In point to the specified frame without affecting the duration of
the media.
•
End: Sets the Out point of the source media, in constant and variable speed modes.
Adjusting this parameter moves the Out point to the specified frame without affecting the
duration of the media.
•
Duration: Sets the total duration of the source media. If Time Remap is set to Constant Speed,
adjusting Duration also affects the Speed and Out point. If Time Remap is set to Variable
Speed (in the Timing controls of the Properties Inspector), adjusting Duration does not affect
variable speed playback.
•
Linked Objects: Use this list to see all objects in the Layers list that are linked to the selected
source media in the Media list. The first column shows the name of the group containing an
instance of the source media; the second column shows the layer name. Changing the layer
name in the Layers list updates the name appearing in this list.
•
Replace Media File: Use this button to relink media in your project to a source file on disk. This
feature is primarily useful for relinking offline media, but can also be used to change source
media (changing all layers that are linked to that source media).
•
Metadata: Use this information pane to see the properties of the media file on disk that is
linked to the item selected in the Media list.
About networked disks and removable media
Be careful when adding media files from a remote server to your project. Although the File
Browser can access the contents of disks on other computers on your network, dragging
remote media to your project does not copy the source file to your computer. The media
source file remains on the remote disk. As a result, when that remote disk becomes unavailable,
the corresponding item in your project goes offline. Further, depending on the speed of your
network, you may experience performance issues when using media files on other computers.
Ideally, copy all media files used in your project onto a disk that’s physically connected to your
computer. If you must use media from a networked hard disk, ensure that the drive is always
mounted on your system and that you have a high-performance network.
This is especially true for media from removable devices, such as flash drives, DVDs, and
removable hard disks that are frequently disconnected from your computer. Always copy media
files from such media to your local hard disk.
