Media Encoder Extrememly slow to render since new update v25

[OBDDESIGN]

Hello, I recently updated the new version v25 of media encoder and videos that usually export in a few minutes are now taking hours. I am exporting from After effects and have used the same process / settings as previous versions, so dont undertand what is going wrong. Any help would be much appreciated to resolve this.  I have attached a screenshot of a current export. Thank you.

I noticed that you use Software Encoding and that may explain it since it is much slower than Hardware Encoding. Try to set the Performance to Hardware Encoding and see if it helps.

[OBDDESIGN]

Thanks for your comment, i changed to Hardware, however that has not seemed to have made a difference.

Can you please share your specs (OS, CPU, GPU, memory) and maybe some performance comparisons?

[OBDDESIGN]

Hello, i have attached some screen shots. i have the latest OS and up to date Creative Cloud. I produce a lot of these videos, all similar content and size, and before the recent update to v25 they all exported perfectly fine within a couple minutes.

Isn't it easier just to go back to the AE & AME dev teams and tell them 25.1 is killing peoples workflows and ability to earn money, than replying to everyone here with the same specs requests?

[EckiAME]

Let me provide a bit of context here. I have not been able to reproduce the performance degradations with my Win11 and macOS 15.2 setups yet. There are a lot of parameters why and when this could happen: OS, CPU, GPU, memory, drivers, software vs. accelerated, system add-ons (AntiVirus, Firewalls, ...), external plug-ins, source material, target format, color workflows, ingest presets, exact interop workflows (scripting vs. add to queue vs. export mode vs. quick export mode vs. encoding of projects directly in AME vs. DynamicLink vs. "Import sequences natively").

I started with ProRes workflows exploratory testing  but up to now I did not find any degradations.

Please note that we can increase the likelihood for fixing with exact repro steps and projects and media. That is why I keep asking the same questions over and over again. It is not to give you the impression that we interact. It is the first step towards a fix.

Thanks to everybody who helped me with that this year!

The problem with your reply, is that as everyone points out, it just didn't happen last month when we were still using AE & AME v24.

I still have v24 on my Mac, I opened the same file in it and AE & AME performed exactly as they used to – much faster.

Can I suggest now that AE is getting so tricked out and memory intensive, that you add options at start-up to toggle/switch off features that we don't use like 3D and AI?

They're going to be no use to anyone if the only people who can use it are those that can afford top spec Mac Studios or Mac Towers.

I have just updated to 2025 and noticed a drastic difference in render times. I think I may stick with 2024 for now.

[EckiAME]

Can you share what media and presets you use, as well as your specs (OS, CPU, GPU, memory)?

[CaineMcG]

M1 Pro, 32GB Ram, macOS Sequoia, 1TB Hard drive. Not sure where I find CPU anf GPU, but I've never had an issue with the rendering speeds in 2024. 

H264, hardware encoding, 1080x1920. 

[chrisboyd01]

Yes both AE & AME 25.1 have made my brand new 12 core, M2 Pro, Mac Mini, 32GB work like an absolute snail.
Any way to turn off the 3D and Ai functions I don't use? I suspect the slowness is all about these additional features.

I got the same issue Rendering a 25 second video takes more then 4 minutes. While exporting the same video takes 10 seconds in Media Encoder 2024. I got Macbok pro M3 MAX 64gb RAM

Can you share the files? I can private message you the instructions via private message in this forum.

Same problem as others users. Render really slow with Media Encoder.

I have notice that when I include text layers in AE, the render process in Media Encoder is really extensive.

I have try just with 1 video layer 1920x1080

10 minutes video

1 layer of subtitle

The render process with Media encoder 2025 is about 1 hour.

With Media Encoder 2024 4 minutes.

My computer:

MacStudio Apple M1 Max

32 gb RAM

MasOs Sonoma 14.5

Any advice?

Thanks for the support!

[EckiAME]

Did not repro for me in ProRes on my MacBook Pro (M1 Max). Can you share the project? I can private message you the instructions in this forum.

[defaultwnuia5tfyrve]

Hi, thanks for answer. I have tried but company do not let me to share files.

Could you help me in other way?

Thanks

[EckiAME]

I will continue to try to reproduce your issue.

[P. M. Hudson]

Same here. Adobe Encoder 2025 is an order of magnitude slower than previous iterations. Happens with any project file I've tried. Converted old ones and newly created ones.

(20+ year Premiere Editor here)

What are your specs (OS, CPU, GPU, memory)?

[Dave Hargest]

I'm also encountering really slow render times, such as taking 10 minutes just to create proxy file of a single 30 second clip. 

Exporting a finished video is taking 20-30 minutes for a bunch of single clips linked together, couple of text layers and a colour layer. Would normally take 1-2 minutes tops before this update.

[rogey0101]

Same here. 

Very slow exoprt times. 

I think i'll return to v24 for now

[EckiAME]

I would like to look into your issues. Do you have a sample project and comparison numbers for me? Also: what are your specs (OS, CPU, GPU, memory)?

2025 UPDATES ARE A MESS!  FORCED TO USE THEM- freeze, don't finish encoding, slow, errors, using more space?! - tried to be loyal , but when you pay this much and there is SO much messed up? what is the POINT? 

[oleh_5683]

Same problem here. I noticed that when rendering in Premiere Pro, it works as usual and the GPU is utilized, but when rendering in AME, it takes 5 times longer, and the GPU isn’t being used. The settings are identical, and hardware encoding is enabled.
