Relativer Dateipfad

Relative Pfadangaben beziehen sich, im Gegensatz zum konreten Speicherort einer Datei, auf einen Speicherort ausgehend von der aufrufenden Datei. Somit ist es möglich, eine einmal festgelegten Ordnungshierarchie auf andere Laufwerke oder Rechner zu transferieren, ohne externe Dateien (Footage, Texturen, etc.) neu verlinken zu müssen.

Die Dokumentation von Resolve und Fusion sagt dazu Folgendes:
The Magic Comp Variable
Loaders and Savers use the absolute file paths for the location of media. However, if you are using Fusion Studio, you can use a file path that is relative to the saved composition location. The Comp variable works for Loaders and Savers and helps you to keep your work organized. Entering Comp:\ In place of the full file path name is a short cut for the folder where your Fusion composition document is saved.
So as long as all your source footage is stored in subfolders of your Comp folder, Fusion finds that footage regardless of the actual hard drive or network share name.
You could, for example, copy an entire shot from the network to your local drive, set up your Loaders and Savers to use the Comp variable, work all your magic locally (i.e., set up your composition), and then copy just the composition back to the server and issue a net-render. All render slaves automatically find the source footage.
Some examples:
Your composition is stored in:
X:\Project\Shot0815\Fusion\Shot0815.comp
Your source footage sits in:
X:\Project\Shot0815\Fusion\Greenscreen\0815Green_0000.dpx
The relative path in the Loader node would then be:
Comp:\Greenscreen\0815Green_0000.dpx
If your source footage is stored in:
X:\Project\Shot0815\Footage\Greenscreen\0815Green_0000.dpx
The relative path in the Loader node would then be:
Comp:\..\Footage\ Greenscreen\0815Green_0000.dpx
Observe how the two dots .. set the directory to go up one folder. Pretty much the same like CD .. in a command shell window.
