After-Effects renders videos too big of a filesize; how to reduce filesize?

Problem: I render After Effects Video and get a file size too big - 4GB!
Broken Solution: Use Adobe Media Encoder, but it is not supported by ExtendScript - 160MB (25 times smaller).


More information below:

ExtendScript

var rq_item =app.project.renderQueue.items.add(comp); // add the comp to the render queue

rq_item.outputModule(1).file=File('~/Desktop/out.mov'); // set the output path

rq_item.render=true; // set it to enabled (is the default)

app.project.renderQueue.render();

 

However, the size of the 1080p rendered video is about 4GB. It is just a very simple 2 minute video.

 

I had this problem with After Effects before. To solve it, I was told to use Adobe Media Encoder. This solved my problem. For some reason, using Adobe Media Encoder to render the After Effects file drastically reduces the file size to 160MB. A lot of online forums say "Use Adobe Media Encoder" as a solution to the large file size problem.

 

I heard from other posts (no official posts) that ExtendScript does not officially support Adobe Media Encoder.

 

How do I modify the above ExtendScript to make it as effective as me using the Adobe Media Encoder to render the video to have filesize 160MB instead of 4000MB?


Any workarounds? Or maybe a way to automate the use of Adobe Media Encoder via commandline?

 

 

Thank you!
