Apple Compressor 2 - Manual (Page 230)

230 Chapter 17 Creating and Changing Destinations
To change the default destination:
1 Choose Compressor > Preferences.
2 Use the Default Destination pop-up menu to choose from the list of existing
destination presets.
The destination you choose appears as the default destination when you import a new
source file in the Batch Window.
Warning Triangles
When there is a problem with your destination, a yellow warning triangle appears. You
must resolve this problem before you can successfully transcode. Warning triangles
appear in the Destinations tab in the Presets window if the destination isn’t reachable
or writable, and in the Batch window if:
 There is already an identical file at that destination.
 You have two destinations with the same name.
 The destination isn’t reachable or writable.
The warning appears at whatever level the problem originated (preset, job, or batch),
and propagates upward, so that if the problem occurs at the preset level, you see
warning triangles next to the preset and job.
If you hold the pointer over the warning triangle for a few seconds, a tooltip displays
information about the nature of the problem. As soon as you resolve the problem, the
warning triangle disappears and you can continue to transcode.
