I have a project with a temporary audio file. I use Soundkeys from Trapcode to create a visualizer. I need to render the project automatically and change the audio file to some other file every time, changing the visualisation. I already googled and came to Dataclay's Templater 2, but this software is expensive and I an still a student.
So my question is: Is there a way to change media in an after effect project and send it to media encoder to render it from the command line?
