Adobe Media Encoder rendering AE projects extremely slowly

[Teagan5C5E]

I started the rendering of like a 3-4 minute video, which usually takes less than 30 minutes to render.

It's taken over 11 hours and still thinks it has 5 hours to go. On a 3-4 minute AE project video in Media Encoder.

WTF is going on!?

After Effects and Media Encoder are only as powerful as the computer we run it on and renders as fast as said computer can render - mostly.

If you're running the lastest version of After Effects, you can use the Composition Profiler to see exactly which layers are taking a long time to render.

Other render time improvements include Speculative Preview and Multi-Frame Rendering, more about that here: Feature summary | After Effects (October 2021) (adobe.com).

If you happen to be rendering to H264, double-check under the Encoding Settings for Video if the Performance pop-up menu can be set to Hardware instead of Software (Hardware should not only be faster, but also be a smaller file).

A general workflow issue to look at is whether or not you're using a CODEC that's good (and fast) for editing.  Any of the Smart Rendering options will do.  Smart rendering in Premiere Pro (adobe.com)
