Multi-Frame Rendering is here! (AKA The multithreading you’ve been asking for)

[TeresaDemel]

Multi-frame Rendering is here for After Effects beta users. Right now, you will have access to Multi-Frame Rendering for export only. Keep your eye on this forum, as we will be rolling out new features until we launch.

Internally, we have been testing a representative sample of projects with a suite of hardware configurations, and we are excited to finally put this feature in your hands and get your feedback. Test your unique projects on your own hardware so we can ensure that our performance updates benefit all of our customers and meet speed and quality metrics before we launch.

Beta testing of Multi-Frame Rendering will last a little longer than some of our other features because we currently do not support Multi-Frame Rendering in Preview, Motion Graphics templates, Dynamic Link, Adobe Media Encoder and AERender Command Line Interface.

Check out the blog and FAQ post to learn the following:

• What is Multi-Frame Rendering?
• What factors influence performance?
• Which effects have been optimized for Multi-Frame Rendering?

Start Testing!
We want to hear from you! Share your thoughts and ideas in this forum.

• How much faster is Multi-Frame Rendering compared to Single-Frame Rendering with your comps on your machine?
• Does our benchmark project perform at the expected speed on your system?
• If you run into specific speed or quality issues with your project, share your project with us at mfrbeta@adobe.com.

Test Your Comps
Test your comps in Multi-Frame Render mode vs. Single-Frame Render

• Use Ae Render Queue to export your comp in Multi-Frame mode.
• Purge both the disk and memory cache, then
• Use Ae Render Queue to export your project in Single-Frame mode. Note: Use the same output module for Single-Frame and Multi-Frame mode. Go to Preferences -> Memory and Performance -> Enable Multi-Frame Rendering (beta) and uncheck the box to use Single-Frame Rendering Mode

Leave a comment and the following information in this forum:

• Your hardware specs: # cores in your CPU, GB of memory, GPU model and amount of VRAM
• Single-Frame render speed (Use “Render Time” noted in your status bar)
• Multi-Frame render speed

If you detect any problems with render speed or quality, submit your projects

• Open your After Effects project
• File -> Dependencies -> Collect Files -> Collect -> Save As (Name Your Folder)
• After Effects will store your .aep file, footage, and text report (file log)
• Zip up your project and send it to us at mfrbeta@adobe.com (or send a link to it hosted on your creative cloud storage if it’s too large to email).

Share the following information in your comment:

• Your hardware specs: # cores in your CPU, GB of memory, GPU model and amount of VRAM
• Single-Frame render speed (Use “Render Time” noted in your status bar)
• Multi-Frame render speed
• Mercury CPU or GPU Mode used

Test our benchmark project and see how your hardware compares
We would love to know how your hardware compares to the results we have gathered from our test suite:

To test the benchmark project on your machine:

• Download the benchmark project.

• Purge both the disk and memory cache, then
• Go to Preferences -> Memory and Performance -> Enable Multi-Frame Rendering (beta) and uncheck the box to use Single-Frame Rendering Mode
• Use Ae Render Queue to export the benchmark project in Single-Frame mode. Note: Use the same output module for Single-Frame and Multi-Frame mode.

Thank you thank you thank you! We at Buck would be dancing in the streets were it not for the pandemic.

• Ryzen 9 3900x 12-core @ 4Ghz w/40GB RAM
• Nvidia GTX 1080 w/8GB VRAM

Using AEPulseBenchmark.aep:

• Single-Frame render speed: 16m 44s
  
• Multi-Frame render speed: 9m 13s

This is amazing.
Great improvements to render times already.

However, if you are rebooting the Render Queue for 2021 you NEED to abandon Animation as the default rendering-codec.

No modern OS supports is. So it puzzles me why it lingers in AE...

Thanks,

Jesper

[jenkmeister]

It puzzles us too... we should do something about it. 😉

Mac Pro (Late 2013) 
Model Name: Mac Pro
Model Identifier: MacPro6,1
12-Core Intel Xeon E5 - 2.7 GHz
Hyper-Threading Technology: Enabled
Memory: 64 GB
MacOs Catalina 10.15.6

My results were 11:03 with multi-frame rendering on (8 concurrent frames) and 22:37 in single frame mode.

The one issue that I hope will be resolved is that during multi-frame mode, the computer became very unresponsive with severe lag in the cursor so that it was impossible to do any other work while the render was going on.  This was not a problem in single frame mode.

While I don't see this as something that could be changed at this point, it seems to me that it would be very helpful to be able to set multi or single frame mode on a per-item basis.   If multi-frame rendering is not practical on some animations - say due to a plug-in incompatibility - it would be nice to be able to simply set the output module to control which mode is used.

[jenkmeister]

Thanks for reporting about the lag. Right now MFR will try to use every bit of your system it can. But we are looking at options for users to be able to dial up and down the amount of the system resources being used so you could say, still do email, or chat, or even do other work while AE renders. That'll come online in the coming months once we've worked through a bit more of the design. 

In terms of per item MFR / SFR settings, we can certainly spend some time thinking about it. Eventually, whether an effect / plugin is compatible, MFR for that comp/effect will still be as fast or faster than SFR. So hopefully there isn't a need to turn it off. But if we can find some cases where MFR is slower, we can prioritize identifying that and perhaps just pulling it back to SFR automatically for you. 

Just as an FYI for everyone, this beta won't be over in a month. We have released this now, really as an early access look and an opportunity for testing across a wide variety of systems and compositions. We need the time to make this work for everyone so we'll take as much time as we need to do that. 🙂

MFR is great so far - more then 2 times faster then single core rendering!

Adobe great job that multicore rendering is finally coming!

I'm really exited and can't wait to put the RAM preview on a test drive 😉

I think my 32 GB RAM are not enough for 16 Cores might that be a bottleneck?

How much RAM is recommended per CPU Core?

Cheers, Felix

[jenkmeister]

We don't have final recommendations just yet, but it's looking around 2-4GBs per core but it is somewhat dependent upon the resolution and complexity of your comps.

Render in Prores 422 Multiframe - Mercury CUDA rendering - 7:56
Render in Proress 422 Single Frame - Mercury CUDA rendering - 11:27

I expected a bit more, certainly comparing the results of the other setups here 🙂
But hey, I'm just glad something is happening on the speed front of AE 😄
In the info zone, I saw that 8 frames were concurrent rendering while in Multiframe rendering.

[Felix Van der Hallen]

So, I noticed there was something holding my CPU back in Ryzen Master, I reset the whole software and got the following rather satisfying result. 🙂

Render in Prores 422 Multiframe - Software rendering - 4:19

Wow!

Single-frame: 13 min, 10 sec

Finally feeling justified in buying all these cores for my work machine.

[jenkmeister]

As much as we'd be delighted at that sort of improvement, I think your MF render was probably reading from disk or RAM cache. You should purge memory and disk caches before the MFR run just to be sure. 

[Jesse Kerman]

Ooof — you're totally right. My bad for not reading the instructions close enough!

Still, 4 min, 17 seconds is a great improvement!

[christianherbstreuth]

@Jesse Kerman 

Hi, i have the same Setup, exept the Vega II. But i am thinking of an update.

So it woukd be nice to know, did you use Software or GPU/Metal Support for rendering ?

[Jesse Kerman]

@christianherbstreuth — Those numbers were for Software rendering. I just tried out a multiframe render with Metal, and that ended up being just a little faster at 3min, 48sec compared to the 4:17 I got for Software rendering.

Great result

[ccced]

It uses just one CPU on multi CPU machines.

All the threads are at 100%, but just on single CPU. I guess this is just something they forgot to think about.

Hopefully they fix it.

It is already double faster compared to singleframe, hopefully goes further with full multi-cpu implementation. 

[jenkmeister]

Can you tell me more about what you're seeing? I'm not sure I understand the "just one CPU on multi-CPU machines" statement. Perhaps a picture of task manager or the activity monitor? 

[Nick2049]

They mean one board with multiple physical CPU's.

I.e. a server board with 2 x XEON's
