There are tons of reason why the rendered file is over large. Mostly, it is because you’ve selected an lossless codec, as like, Apple Pro. Res and AVC-Intra. They are quite different from the H. 264, HEVC, VP8 and many other high-compressed codec.
Another thing we asked ourselves was why does after effects take so long to render my work?
After Effects can take advantage of several GPU technologies, like Open. GL and Metal, these allow you to render your compositions using high-performance graphics cards quickly. While convenient, this feature has been known to cause render problems from time to time.
How to fix rendering problems in after effects?
By using the Render Queue, Media Encoder, CPU rendering, flushing the cache, and the elusive “secret” settings menu, hopefully, your rendering issues are far behind you. Now that you’ve solved your rendering problems, there’s a lot more to do in After Effects.
How to fix after effects rendering problems during export?
Whenever you add effects, images, or video clips, After Effects must render the results for you to preview or export. This process is largely done in the background, without your knowledge. But sometimes during the final export, rendering problems can pop up unexpectedly.

What is after effects cache and how to use it?
Behind the scenes, After Effects is storing renderings of your work as you go. This allows you to quickly preview your composition without having to wait on render times as you work. Generally, this is a helpful feature, but sometimes cache files can become large or contain errors that disrupt your rendering performance.
While I was researching we ran into the inquiry “Does after effects use GPU or CPU for rendering?”.
Switch to CPU Rendering Instead of GPU After Effects can take advantage of several GPU technologies, like Open. GL and Metal, these allow you to render your compositions using high-performance graphics cards quickly. While convenient, this feature has been known to cause render problems from time to time.
