Loop points are used for “motion menus”, e.g. you can have a 15 second motion menu and then have the buttons appear at a given time, (say after 10 seconds),and then you can instuct Encore to loop the motion back to this 10 second time interval and also to have it loop back to this time for as long as you need (set it to loop forever, and it will do as instructed),Hope this helps
