Report duration of all projects Comps

[Filip Vandueren]

This should do it…
right now it just writes the result to the Javascript Console of the extendscript editor, and displays a dialog.
If you have a hundred comps in the project, that dialog might get bigger than the screen, just hit enter !

comps=extractCompItems(app.project);

report="Comp-length Report\r";
for (c in comps) {
report+=("Comp \""+comps[c].name+"\" has a duration of "+comps[c].duration+" sec\r");
}
$.writeln(report);
alert(report,'report');

function extractCompItems(prj) {
comps=[];
if (prj.numItems) {
for (i=1;i<=prj.numItems;i++) {
it=prj.item(i);
if(it.typeName=="Composition") {
comps.push(it);
}
}

}
return comps;
}
