Okay, sorry about that.
This is what is going on/what I would like to be able to automate:
I’m starting at 0:00:00:00.
Select ALL layers in the Pre-Composition, and create an Opacity keyframe with a value of 0%.
Then I move forward 5 seconds to 0:00:05:00, select only the bottom layer, and create an Opacity keyframe with a value of 100%.
I then select only the layer directly above the bottom, and move backwards 2 seconds to 0:00:03:00. I create an Opacity keyframe with a value of 0%. Then, staying on the same layer, move forward 5 seconds to 0:00:08:00, and create another Opacity keyframe with a value of 100%.
This process continues until all the layers in each Pre-Composition have been keyframed.
So all of this is basically just gradually fading in text layers, but I would like to find a way to automate this part of the workflow.
