Mogrt duration

Depends on what you want to do, but start by considering what you are saying here: 10 seconds to 30 minutes? That is insane! Even under worst condition such a template should at least be 30 seconds long or else you'll inevitably run into all sorts of problems when values simply run out, stuff is no longer synchronous or you simply see the cycles of repeating content all too obviously. The rest will require more specific info about what you want to do. From using time-protected regions to rigging Essential Graphics with elaborate expressions everything is fair game, but the specifics really come down to what is required.
