Change Render Locations is included with the regular After Effects installation – go ahead, look under File > Scripts, there it is – and it solves one tedious After Effects workflow issue, that you can’t reassign multiple items in the Render Queue to a new render location.
Before selecting the script, make sure any render destined for a new location is checked, as that’s how this scripts knows which render location to move. Now simply assign the new location, and you get confirmation of the new output path.
Badabing, badaboom.
