FootageItem.replace()¶
app.project.item(index).replace(file)
Description¶
Changes the source of this FootageItem to the specified file.
In addition to loading the file, the method creates a new FileSource object for the file and sets mainSource to that object. In the new source object, it sets the name, width, height, frameDuration, and duration attributes (see AVItem object) based on the contents of the file.
The method preserves interpretation parameters from the previous mainSource object.
If the specified file has an unlabeled alpha channel, the method estimates the alpha interpretation.
Parameters¶
| Parameter | Type | Description |
|---|---|---|
file |
Extendscript File object | The file to be used as the footage main source. |
FootageItem.replaceWithPlaceholder()¶

Description¶
