Export selected Movie Clips in library to PNGs and keep the name of the MC.

Hi I am trying to modify this script to export selected Movie Clips from library to PNGs and keep original name of the MC. I have the script that works well exporting selected bitamps from library, but I am trying yo modify it to export also Movie clips.

function exportLibraryImagesToFiles() {
	var doc = fl.getDocumentDOM();
	if (!doc) return;

	var selectedItems = doc.library.getSelectedItems();
	if (!selectedItems.length) return;

	var folder = fl.browseForFolderURL("Choose an output directory.");
	if (!folder) return;

	var i, t, sym, bmpName;
	var count = 0;

	for (i = 0; i < selectedItems.length; i++) {
		sym = selectedItems[i];
		if (sym.itemType != "bitmap") {
			continue;
		}
		bmpName = sym.name.split("/").pop();
		// strip original extension
		t = bmpName.lastIndexOf(".");
		if (t != -1 && ["jpg", "jpeg", "png", "gif", "bmp", "psd"].indexOf(bmpName.substr(t + 1).toLowerCase()) != -1) {
			bmpName = bmpName.substr(0, t);
		}
		// do the thing
		sym.exportToFile(folder + "/" + bmpName + "." + (sym.compressionType == "photo" ? "jpg" : "png"));
		count++;
	}
	alert(count + " image(s) exported.");
}

exportLibraryImagesToFiles();
