Increasingly longer and longer export times

I hope everyone's having a good week so far!

 

Questions I'm looking to get answered:

  • Is this a bug/technical issue on Adobe's/AME's end?
  • Anyone have a good workaround or some handy tips or tricks to speed things up on a series of simple 1080p 30fps videos? (I'm exporting out as an MP4 at 1080p/30fps, no audio - but if it would be easier to convert to something else and take it into Premiere Pro, let me know!) 
  • Does anyone know why this is happening?

 

So, long story short, I'm exporting several videos out of After Effects through AME, 30 videos to be exact. Each video is fairly identical, even on the backend. The videos have the same duration (30 seconds), same size and settings (1080p/30fps), all estimated to be roughly 38MB, they all have the same assets, same layer structure, same effects, etc.

 

Each one is a 3D video, much like those 2D to 3D photo videos where you just mask things out seperately and bring them into AE, and only one of the photos has any animation/effect - just a slight nudge to rotation and position, while the rest of the layers are still, and there is slight 3D camera movement with depth-of-field turned on. All are set to 1920 x 1080 px, 30 fps, no audio, H.264/MP4.

 

Here are the render times:

  • Video 1: 29 minutes (when I ran this one before it originally was at 8 minutes)
  • Video 2: 37 minutes
  • Video 3: 1 hour 11 minutes
  • Video 4: 6 hours 38 minutes
  • Video 5: 10 hours 17 minutes (I didn't let this one finish after it didn't budge for the first hour)

 

Again, all the videos are almost identical, and not that large in size. I feel safe to say my PC isn't the issue, as I just had a hardware check last week, all my drivers are at the version they're supposed to be, and I've cleaned and cleared the caches on Monday, etc. 

 

Specs:

Intel(R) Core(TM) i9-10885H CPU @ 2.40GHz 2.40 GHz

NVIDIA GeForce GTX 1650 Ti

32.0 GB (31.8 GB usable)

 

Any help is much appreciated, and if you made it this far - thanks for reading!

+1 for this problem

 

This is absolutely insane. I've have 35 of 1 min each, comps rendered in 1920x1024,60 fps, Progressive, nothing complicated in them. Literally 3 texts on them with a fade in-fade out. 

I've put them to render 12+ hours ago and they are still not done. I have clients waiting for them. Risking my job just because adobe is absolutley insane lately.

We were not able to reproduce the slowdowns yet. Would you be able to provide a project with files?

So I took the comp with all the precomps and switched the output to .MOV through Apple ProRes 4444 - plan on cutting it up and converting it back to an MP4 through Premiere once all is said and done. However, the export time is out at 8 hours - compared to 42 hours. I'm a bit peeved still, since this isn't a new type of video that I'm working on, this is one of several in a series and I've never had such long render times on H.264/MP4 files before - this is just adding extra time and redundant steps.

 

However, I should note that this was after I started the render and it estimated 5 hours and was trucking along pretty well. I stopped it to cut some time down on the precomp to see if I could speed it up and it jumped to 17 hours, barely budging and moving at a snail's pace. Then I went back, undid the adjustments I made and popped it back into AME - 33 hours (instead of 5 hours.) Then I just went and remade the comp the exact same way I did before and now it's 8 hours and finally moving. So I am just done touching it as not to upset the Media Encoding higher powers.

 

I'm just adding this all in for notes, I'm just really curious why After Effects/AME can have such variability in render speed on the same project or relatively identical projects. 

 

Is there a specific Media Encoding diety, a rendering prayer, or some ritual I can do at a time like this? 😅

I also tried to put half of the comps into a single comp and that is projected to render at 42 hours - even after 30 minutes of rendering.
