I do NOT need any information about the new features.

I just wanna know why the bloody hell AE only uses one single core of my computer?

It has continuously rendering for over 170 hours.. always ONE CORE.

Any idea? Can anyone help me? The project is overdue already but I have to watch this nonsense.

This is so frustrating.

This is the latest version.

This is something you should have known already: After Effects only uses one core.  This may be your first post so you didn't seek advice before you began.  Any advice we could give now requires that you stop the render to provide diagnostic information.

You, sir or madame, are STUCK at the moment. Big-time.

You can't stop the render for fear of missing the deadline by even more than you are already missing it.  Pray you haven't made a mistake.

The bright side:  you can do a post-mortem to help speed things along on future projects.

If AE can only use one core, so what is the point I seek advice before I began?

So let's say I haven't begun. What would you do to make the render faster?

Buy this: RenderGarden | by Mekajiki

The best rendering option for AE. Easily up to a 50% decrease in render time and you can still keep working in AE while your comp is rendering.

So adobe will never make AE multiprocessing?

And we have to pay more money to make this software efficient?

Who said that AE won't use MP ever? It's perfectly possible that one day it will, but even then the usual limitations apply. A lot of video processing simply is linear and can only run on one thread. That's not even AE's fault, it's a simple computational math thing plus factors like CoDecs not being threaded, effects breaking GPU acceleration and so on. You simply have the wrong computer for AE and expect magic things. I've written about this stuff a ton of times on this forum, so do a search for more explanations.

RenderGarden is awesome. Works perfectly for me! It's embarrassing to see that we have to resort to a third party plugin to get what AE should provide natively. I keep praying for Adobe to better utilize the resources we all have in our computers!

I, in fact, do not blame that some of the process only works in a "linear" way but at least there should be a document to tell us what is going on so we can make changes based on that.. It is so embarrassing, I agree, that we need something third party to make it at least use some of my cpus.

Just like some of the 3D software, in one frame you give different core a different area to render or assignment different frames to different cores...AE is just making compositing so low efficient and time consuming.

Oh nice. looks like here we have an expert!

To build on what you have said, some features do not run on multi-thread,  would you like to share a doc talking about everything that only use one core?

Your reply in simply useless unless there is something can help us to really better utilize this software.

There is a reason for this -- Adobe is more concerned about luring in new Creative Cloud renters than it is in fixing the basic functioning of After Effects.  Thus, a lot of time is spent developing sparkly new features, and little attention is paid to making the application work well.

You dont havet to "pay more money to make this software efficient", I have very little coding knowledge, but I was able to assemble an app using Apple applescript that creates multiple instances and automatically convert those .psd sequences into a ProRes4444 and that ProRes into a .mp4 using ffmpeg.

 

This for me, is way more usefull than that paid solution since with applescript you can automate these task up to whatever need you have.

 

On windows I have no idea how to do this, but I have been told it is posible.Screen Shot 2020-02-25 at 8.41.46 PM.pngScreen Shot 2020-02-25 at 8.42.07 PM.png

Render to PNG files with skip existing (multimachine rendering) on and use this BG Renderer Pro - aescripts + aeplugins - aescripts.com

Saved me numerous times when dealing with heavy composites!

Now, 243 hours has passed. Still 3 hours!

My next step is to gradually give up this piece of rubbish. Cheers! to all those developers!

Have you tried the BG renderer script? you can download a demo... It's one extra step (importing the Seq that was rendered and converting to .mov or .avi) but you can make use of all your cores!

Haha, so many people bought a frikken high-core count PC, when they were actually just better off with an i7-7700 This has been going on for like forever, and is just another statement for how old this software truly is. — So what to do?

  1. Buy Rendergarden. Once setup, it's extremely convenient to use. You can achieve waay more than a 50% usage on a high-core-count machine.
  2. Watch and learn, what AE features go well with render usage. Newer additions like the camerashake-reduction tend to be optimized for multicore processing, while old stuff doesn't (I'm looking at you, layerstyles )

You are right. I have been using AE for many year. This is actually first time I have ever seen that AE only uses one core.

I do 3D most so this is great for me.

In this AE project, only three plugin are used, fractal noise, particular and cc ball, but all the layer either have offset effect + time expression or only time expression. I am thinking it is because this expression because honestly I often make AE use up to 50% use but only this project does not and this is a heavy time expression used project.

The BG renderer Pro script will help you utilize all your cores when rendering. Rendergarden probably does a similar thing though I haven't used it.

With BG renderer Pro you can simply start up multiple rendering instances on the same system. You have to render to image sequences but for render-intensive projects it certainly works fine and I can use pretty much 100% of my dual Xeon CPU power.

Well, afaik BGRenderer hasn't been updated since 2011, plus it doesn't give granular controls over how many processes it'll start. Rendergarden does that. Which is can come handy to balance out export performance.

Perhaps, but updated or not, it still works and it is significantly cheaper than Render Garden so I just wanted to have it out there as a working alternative.

Another vote here for BG Renderer!  (BgR)

It may not have been updated for a while, but it hasn't needed to be! I've used it in production for many years now, through many versions of AE including the latest, 16.0/CC2019.

In addition, Lloyd Alvarez, the developer, actively takes part in the discussions of the script ​so is aware of issues that may come up. Additionally, if/when BgR is updated, I would not be surprised to see new features rivaling many of those found in RenderGarden (RG) and / or RenderBoss (RB). (No insider info claimed - I'm simply a fan of Lloyd's work and his modus operandi is to make it better!)

Personally, I've tested both RG and RB recently and found them both to be great in concept. However, during crunch time they both added more complexity to my workflow than they alleviated. Perhaps if I were to re-test, and/or re-setup before crunch time I'd have a different opinion, but at this point, the granularity of control offered through BgR is, for me, worth the trade-off in automation offered by RG & RB.

At $100, Render Garden more than paid for itself the first time I used it on a render that would have taken more than an hour because I charge more than that per hour and I don't get paid for rendering. I don't know anybody that really does anymore. If they do manage to charge for rendering it is going to be at a significantly lower rate than they get for doing the work.
