Automation Blocks Scripting in AE: Extend Clips and Set End of Work Area

Question

I've been using Automation Blocks' "Create Comp Duplicates from Spreadsheet" to automate the process of taking lists of vertical videos and converting them to horizontal, plus adding an animated lower third of the user's social handle.

Sometimes, the clip that I'm importing is longer than the source clip I have in the composition I'm using as the template, so it ends the imported clip (duplicated on 2 layers) early. So I drag the clips to their full lenghth, select one of them and press "o" to go to the out point of the clip, then press "n" to end the work area at the clip's out point. Is there a way to automate these steps into the workflow? Here is a video of what I do manually that I'd like to automate:

Hi Nick,

just created the following block script for you:

Just select all comp duplicates you created and run the tool. It should fix the workarea + duration of layer 2 and 3 as requested.

You can easily replace the numbers "2" and "3" if you need to process other layers (or duplicated/delete the blocks to process more than two or just one layer in the comp).

The script is attached. I will also upload it to the community library at

"Comps/Duplicate/Comp Duplicator Helper/

For All Selected Comps Maximize Duration of Layer 2 and 3 and Set Workarea.xml"
