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
  • Use Ae Render Queue to export the benchmark project in Multi-Frame mode.
  • 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.

It'd also be interesting to see people's results over various releases - I found that the benchmark project was fractionally slower in recent releases compared to the first multi-frame-rendering release of AE, and that's running on a pretty fast machine - my fastest time was (I think) 3min 23secs.

I also made that observation that it rendered a bit slower than in the beginning but on the other hand now the start up time is much shorter which probably makes the whole process faster in total.

Take a look in the Preferences for Multi-Frame Rendering. By default now, AE will give back 10% of the CPU back to the OS for other applications. You can reduce that to 0% for any benchmarking you want to do. 

 

We are tracking internally on a range of machines and haven't seen any slowdowns otherwise (actually speed ups over the past few weeks as we've turned on the final optimizations), but those can definitely be offset by that CPU % change. 

 

As to an overall leaderboard or stats, we do have that data coming in from beta users. I'll look at preparing at least a report of the data we can share out. It's all anonymous, just computer hardware and rendering times. We also have some external benchmarking companies running tests to get some overall numbers on various systems on various compositions so you can see how different hardware improves. Hope to have that out next month.

The slower rendering on my side was with the Metal option (2018 MacBook Pro) turned on an that was almost 1 minute slower compared to my first test (17:36 vs 18:29). If I find the time I will render both versions CPU and GPU with a freshly started machine. CPU for other apps was set to 0%.

Thanks for listening to us, i think the whole community has been waiting for MFR to comeback for years.

Just one more question: when should MFR go from beta to stable?

Thank you for your continued support, testing and feedback on Multi-Frame Rendering and all the features wrapped up in it. We continue to get closer and closer to moving this from beta into a stable release. We have a few more critical bugs we want to get addressed to make this as good as possible!

 

Today though, AE Beta 22.1x13 has been made available for download. We’d love it if you could download, install, and give it a go this weekend. Some specific changes to look out for:

 

  • Particle Playground is now supported by MFR and with that all 290 effects are MFR supported!
  • Another update to Cineware was added to bring about a bit more stability.
  • Fixes in Rotobrush have brought about not only more stability but increased performance during propagation of long clips.
  • Thanks to a project from one of our beta users, we found an area that the Composition Profiler wasn’t collecting data in. If you use Collapse Transforms on pre-comps containing 3D layers, the profiler should now show data for that scenario.
  • The Reshape effect got a couple more bug fixes for bad output. If you use that effect, please load up your project and let us know if you see anything still broken.
  • The Warp effect (not warp stabilizer) had a crashing bug fixed in it. If you use that effect, please load up your project and make sure everything is working.
  • Slowdown when playing back already rendered comps with MFR. There were some scenarios where it looked like MFR was re-rendering frames that were already rendered. There wasn’t anything re-rendering but reading the frames post-render had gotten slow, so we fixed that.
  • The AutoColor, AutoLevel and AutoContrast effects were fast, then got a bit slower a few weeks ago, but we fixed that so those are now fast again with MFR.
  • Unrelated to MFR but in this build, Motion Path Tangents in the layer window stopped appearing in a previous release. They are back now.
  • We found some scenarios where AE compositions when rendered from AME were crashing AE. We should have those fixed now.

 

Our goal is to get those remaining critical bugs sorted out this week so be on the lookout for more updates very soon!

 

Thanks again,

Sean

Thanks for the update, Sean.

 

It seems I'm still experiencing slowdown with already rendered areas on the timeline. It's a very simple project, so I'm not using a lot of layers or complex effects or anything. I'm happy to share the project though, if it helps.

Might this be related to my issue? The timeline is also completely pre-rendered / green, because it's such a simple project. And it's just not playing back smoothly at all.

In this case, it's actually playing back on once rendered, but during render the CTI and playback is falling behind where the frames have already been rendered and cached. But maybe.

Running a 3950x with RTX 3080.... It is barely utilizing any resources during media encoder render (using all hardware H.264 encoding with CUDA). My caches are on 2 different M.3 3500 Mb/S drives (one for cache, one for conformed cache). Disk drive usage is minimal. When RAM previewing it maxes out at about the same CPU usage, and usually hovers around only 2-3 concurrent frames. This is not the benchmark comp, but a real-life use case.

Running a 16 core Mac Pro 2019, 192gb Ram, Dual Vega II graphics and the latest OSX and after effects versions, and for some reason, suddenly I can't get smooth playback anymore out of the beta. Even the simplest animations like a scale between two keyframes don't play back in realtime in an HD comp any longer. The same projects work flawlessly in the regular After effects v18.4.1. 

 

MFR enabled or disabled, no difference. Something very strange must have been broken with one of the last updates.

Please take a look at the attached video.

Was that with MFR disabled? The info panel isn't showing anything about concurrent frames so I'm not sure.

(for HolyStrokes.com):

I would suggest restarting your machine and seeing if it's still happening. Unfortunately there are still some issues with AME talking to AE which are normally resolved with a restart (so that the dynamic link system is restarted).

Yea, MFR was disabled, but it didn't make a difference wether it's was on or off. I'll send you the file tomorrow when I'm back at the office! Sadly a restart didn't help. I already had the issue on Friday and then hoped that the latest update that I installed this morning would've fixed it, but no. 😞

Also it doesn't really seem to be project related. I made a new one specifically for the purpose of showing it to you and it was reproducable.

I want to  add, I did install the latest OSX update on the night Thursday to Friday and after that I noticed the issue for the first time. Could that be related somehow?

Thanks for the projects and feedback over the past week. Hopefully we've taken care of a bunch of those issues. Rolling out today is 22.1x24 which has a few more fixes I wanted to make sure folks know about:

 

  • Thanks to some of our beta users, we identified an issue that could affect smooth playback of cached frames in the composition window. This should now be fixed so please let us know if you're still seeing issues that sound like that.
  • The new Cinema 4D integration wasn't allowing C4D specific plugins to work when used in the AE workflow. This is now fixed.
  • If you use the date and time variables in the "output" section of the render queue, those variables weren't being replaced correctly. This is now fixed.
  • In the layer windows, when using Rotobrush, the propagation markers may not have been accurate when purging frames or changing effect parameters. This is now fixed. 
  • Multi-Frame Rendering could cause previews to extend past the available RAM allocated for a preview and as such cause a slowdown in AE's overall performance. MFR should now act a lot more like MFR-off when it comes to respecting RAM and stopping preview caching when detecting low memory conditions. 

 

Again, thank you for your continued support and feedback!

WOO HOO Great job Adobe!! This made my week. It's so nice to be able to finally stretch my CPU legs in AE. I'll try some of my other projects in this new version. Hopefully I'll have the same results.

Was excited to heard about this feature but AE only using only 13% of the cpu during the whole proccess...

 

Have you guys at Adobe thought about buying and implenting rendergarden from toolfarm as an standard render technology native to after effects?  If you havent you should since that solution really works.

That doesn't seem right. We have 30,000 MFR renders happening in Beta per day with much improved performance. Can you a) confirm that MFR is enabled in Preferences -> Memory & Performance and b) tell me more about the project you were rendering?

I get the same. All my footage and caches are on 3,500 mb/s NVMe drives, have 64GB ram and my 64 core 3950x maxes out at maybe 25-35% utilization. In app RAM preview does maybe 2-4 simul frames max.
