I am placing videos horizontal which cross 15k if it cross and i enabled scroll to group it will become blank, if i add same in scene it works but scene will not work as per my requirement, i need group only and it has accept upto 70k . While scene will take horizantal that much video still you can;t see but if you enable scroll it will scroll smoothly.
