Not an expressions question but an ExtendScript question. But I get the impression this crowd might know a thing or two about After Effects scripting, too ;-)
So I'm taking Lloyd's FXPHD scripting class and getting my feet wet in scripting. I'm trying to build a script that will create comps for all selected footage items, apply an animation preset and render to a specific location. Lloyd's course is an excellent start since a good chunk of what I need is covered.
But the thing I'm now strugling with is that I want the user to set the output path for the new files. So I've put in a 'browse' button, but the file.Opendialog isn't what I need I think and I can't figure out what I do need instead of this:
var myOutputPath = File.openDialog("Select output path" );
And there's no such thing as Folder.openDialog it seems...
