After Effects running extremely slowly - can a composition be made less computationally intensive?

Hi
I am currently making an explainer video (around 1.5minutes long).

It's only around half way through at the moment (and at a pretty rough stage), however, After Effects is now running too slowly to practically work on it any longer. Both RAM preview and even just moving objects on the screen takes an extremely long time.

 

My computer is a relatively old and I am guessing this is possibly largly contributing to the problem, however, I am wondering if a large part of the problem is also the way the animation is made? And whether the same animation could be made in a way that is less intense on the computer?

(As I would preferably not purchase a new one just yet)

 

However, am also uncertain if the computer is the sole problem, as  I borrowed a virtually brand new base model 14-inch Macbook Pro 2021 to work on this file also.

Apple M1 Pro chip, 8-core CPU with 6 performance cores and 2 efficiency cores

14-core GPU, 16-core Neural Engine, 200GB/s memory bandwidth

16GB unified memory, 512GB storage (almost completely empty)

 

This coped with the file much better, though started to slow down alot by the time I got it to the stage attached in this post.

 

I have attached the After Effects file and an export of the file.

 

Details:

 

My computer:

MacBook Pro (Retina, 15-inch, Mid 2015)
Processor: 2.5 GHz Quad-Core Intel Core i7

Memory: 16 GB 1600 MHz DDR3

Graphics: AMD Radeon R9 M370X 2 GB,
Intel Iris Pro 1536 MB

Storage: 500GB SSD (149GB available)

Operating System: macOS BigSur version 11.5.1

 

It is also usually connected to an external monitor, but the problem occurs regardless of whether it is connected or not.

 

After Effects 2022 (version 22.1.1)

 

The After Effects file: 

6.97mb

It has 254 layers, of which 60 are not in use at the moment / being kept not visible.

It's mainly just simple position and opacity changes being keyframed, though motion blur is being used on around 35 layers for a short segment.

 

So far, I am guessing the main problem is the numerous layers, as every shape is on a seperate layer.

Mainly the 64 rounded corner squares that appear early on, and the roughly 40 thin black rectangles that appear towards the end, as they will all need to move and change colour in slightly different ways.

 

Can the above shapes be grouped into a smaller number of layers whilst still being animated differently? 

(e.g., using just one shape layer with numerous shapes within)

Can these shapes  currently there also be grouped without having to remake/re-animate them?

 

Would this make it less intense for the computer to process / help resolve the problem?

Or are there any other suggestions that may help resolve this problem?

Would anyone recommended a minimum computer spec to deal with this file without becoming too slow to practically work on?

 

Thanks for any information.

After Effects is only as powerful as the computer we run it on.

Equiloud on Vimeo makes an AE test project available that can be downloaded and run and the results can be compared to what's been posted in the comments or to what i've listed below.

 

Here's the link: https://vimeo.com/118053656

 

The results I've listed are all prior to Multi-Frame Rendering being available.

Thanks for the response.

 

I understand After Effects is heavy on computer processing power.

However, I have not used After Effects much and I am uncertain the file I made has been made a way that makes it harder to process than it could be if done in a different way?

Or if having so many shape layers would be a typical way of making something similar to what I have made?

Could the numerous shapes be grouped into a few shape layers, and would this affect the RAM preview much or at all?

 

My Macbook rendered the file in 9min 40seconds

Though, I am uncertain what the relationship is between the the render time and RAM preview performance is?

Other than that they may be generally linked. Is it a mostly linear relationship?

Will a computer that can render in half the time be twice as fast at loading RAM preview..?

 

Thanks
