Just like the title says, I would like to create a batch file that will:
1) call the After Effect engine to open specified project
2) change the text
3) save the project
4) then I can render a video with aerender.
So far from what I have read, steps 1-3 need to be done using scripts. This is the crux of what I am trying to do and something simple in concept seems difficult to solve. Has anyone solved this or does After Effects have an easy way to do this?
