Hi
I have a large number (hundreds) of video files where I need to do the same correction so I was looking for a way to automate this process as much as possible. And I found the Replacer script.on site oizys org
Here is its code.
/*
After effects script
This will take a template and add multiple compositions after replacing a source.
It will open a fileselector
This will replace the source of a layer. The layer should be called 'replace'. Then it will copy the composition and
do the same for another file picked via the fileselector.
*/
{
function SmartImport() {
var scriptName = "Example replace";
// Ask the user for a folder whose contents are to be imported.
var targetFolder = Folder.selectDialog("Import items from folder...");
if (targetFolder != null) {
// If no project open, create a new project to import the files into.
if (!app.project) {
app.newProject();
}
function processFile(theFile) {
try {
// Create a variable containing ImportOptions.
var importOptions = new ImportOptions(theFile);
try {
var currentItem = app.project.importFile(importOptions);
for (var i = 1; i <= app.project.items.length; i++) {
var elm = app.project.items[i];
// Look for the template composition
if (elm instanceof CompItem && elm.name === 'template') {
var netItem = app.project.item(i).duplicate();
for (var j = 1; j <= netItem.numLayers; j++) {
// Replace the soure of the item called 'replace'
if (netItem.layer(j).name === 'replace') {
netItem.layer(j).replaceSource(currentItem, true);
}
}
}
}
} catch (error) {
alert(error.toString() + importOptions.file.fsName, scriptName);
}
} catch (error) {
// Ignore errors.
}
}
function processFolder(theFolder) {
// Get an array of files in the target folder.
var files = theFolder.getFiles();
for (index in files) { // Go through the array and set each element to singleFile, then run the following.
if (files[index] instanceof File) {
processFile(files[index]); // Calls the processFile function above.
}
}
}
// Recursively examine that folder.
processFolder(targetFolder);
}
}
SmartImport();
}
It does what I need - im creates a project in AE with a composition "template" in which all the layers that need to be substituted are called "replace".
The script asks you to specify a folder and for each file in this folder duplicates the composition of "template", replacing the layers "replace" this file. I.e. for 50 files in folder it will create 50 copies of the composition.
What I need to improve - is the automatic renaming of these compositions by filename of replacing file. For now its make result as composition "template2", "template3"... etc and im need to rename each composition by hand when im export this composition.
I want for composition where layer "replace" replaced by file aaa.mov, create a composition not "template#" but named "aaa" or "aaa.mov" so that when I send it for export the exported file will automatically be called "aaa.mp4" as well. Its looks like easy mod which can get rid of a certain amount of pointless manual work that can be automated.
The problem is that I am a complete zero in coding and scripting.
I tried to modify a piece of code like this:
if (elm instanceof CompItem && elm.name === 'template') {
var netItem = app.project.item(i).duplicate();
app.project.item(i+1).name = currentItem.name;
netItem = app.project.item(i+1);
for (var j = 1; j <= netItem.numLayers; j++) {
There im change its just added one string in first cycle
app.project.item(i+1).name = currentItem.name;
and its even worked... once for one composition (i.e. composition was created and named as "file name" instead of
template#" but its stopped working for next try, the script caused an endless cycle of copyingcomposition. So im do something wrong.
I hope someone will look and show me the right line.
Thanks
