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.

Correct answer BCSFF

Are you using mp4 in and mp4 out?

Yep. Loading the project in AME 25 Beta now and not having the issue anymore, however I cannot send the sequences directly from PP until the update makes it to release

Having the same issue across multiple computers in our organization. I made a duplicate post by accident.
A brand-new Lenovo Legion with a Ryzen 9 and RTX 4080 12GB is taking 25 mins at best on 25.1, and 2+ hours on the beta.
On my 2021 MacBook Pro 14", it takes 13 minutes.
On several other machines, from powerful to pitiful, it took anywhere from an hour to 3 hours to render, sometimes crashing entirely.

It's definitely GPU utilization related as it seems to affect anything that is an 'accelerated' effect. I have a very resource-intensive 3D test file that I've sent to @EckiAME. I've also included a screenshot of my desktop's GPU use during rendering in AE vs. AME.

The 'workaround' is not really feasible either. Trying to export the same project from After Effects directly eats all of the available RAM and it crashes, even on a 32GB machine with only 4GB allowed for other apps. Disabling 'accelerated' layers and effects just makes your project incomplete.

Here's all the specs again
Render time: 2+ hours estimated

Windows 11 Pro

Ryzen 7 2700x

32GB RAM
NVIDIA GeForce RTX 3070 8GB
Export settings:
Renderer is set to Mercury/CUDA
Source is 3840 x 2160 - 29.97 fps
- Video: Based on source, Hardware Encoding
- Audio: AAC, 320 kbps, 48 kHz, Stereo
- Bitrate: VBR, 1 pass, Target 20.00 Mbps

Hopefully we can get this fixed, it's been months.

I am having the same issue. A video 1:15 long takes 27s to render in Premiere and over 6 minutes in Media Encoder. There is a Lumetri color instance on the video for color correction, and another in an adjustment layer for grade. --> If I delete it from the adjustment layer, then I get a fast render in Media Encoder. <--

The PProHeadless jumps to 3000%+, but the GPU never engages. YES - I have hardware encoding turned on (see attached export setting screen captures).

Mac Pro / 15.3..1 / 3.2 Ghz 16-core Xenon W / 192 GB Ram / Dual AMD Radeon Pro W5700K 16GB

Most recent versions of Adobe software installed. (PP 25.1.0 b73 / ME 25.1 b65)

I updated from MacOS 13.x thinking that might help, since that was long overdue, but it made no difference with this issue.

dont use lumetri color on adjustment layers. that what cause that

This appears to be the workaround for the moment, but this surely needs to be fixed by Adobe ASAP. Having (multiple) Lumetri Color effects within an Adjustment Layer is the entire point of having adjustment layers in the first place, and this never used to be an issue (and frankly still isn't an issue in Premiere, only ME).

Same! This is a serious problem impacting our livelihoods. How can it not be solved yet?? 20 second clip with just a few basic titles, no effects, using GPU taking longer than 12 minutes! It would have taken 10 seconds to export in v24

Any news on when a fix will be implemented for a stable release?

So I found a fix for the slow rendering. I installed 25.2(build 74) BETA of the media encoder. I ran a quick test and it is fixed!!

I have no idea when they are going to apply the fix to the general public.

Awesome! That worked!

I still can't send to AME from the PP Export screen but I am able to open the PP project and render out the sequence at an appropriate speed. Hopefully this gets put into the main release ASAP.

Thx!

I just wanted to chime in here. I'm having the same problem. Has anyone reverted back to 2024 and had better results?

I have not tried because I work with Productions and it converted everyting to 2025. I still have the original directory with 2025 productions projucts but we will loose the last 3 months because we cant convert backward?

Another thing I noticed is we are having this problem with Media Encoder. If we render in Pr it seems to be faster?

Anyone else rendering faster in Pr?

I haven't as my projects are in 25 (pretty sure they won't open in 24). Can you not have both 24 and 25 installed when using Productions? I am not familar with it

Yes you can. But DynamicLink requires matching versions for PPro & AME or After Effects & AME.

We are very sorry for your issues.

We did not observe any performance degradations between 24.x and 25.x. We still do not have a solid repro for the issues you describe. We will keep investigating.

Some users were mentioning no/low GPU usage. Can you please verify if direct transcodes in AME also do not use GPU in your setup? This verification is to rule out any DynamicLink related issues.

I identified the cause of the degradation issue in my workflow, but the only solution so far is a workaround. I use adjustment layers to apply color correction with FilmConvert and Lumetri. In the 2025 version, rendering degrades when these effects are applied via adjustment layers. However, if I remove the adjustment layers and apply the exact same effects directly to each clip, rendering performance returns to normal. This is strange because I've been using these color plugins with adjustment layers for years without issues, but performance has dropped significantly in version 25.x.

Thank you so much for your investigations! Does this also repro without the "FilmConvert" plugin, i.e. only Lumetri?

Does anyone have any useful updates on this issue?

I've had the same problem with AME 25. I even did a clean Mac OS install over the holidays and was surprised to find that AME was still taking many times longer to render than straight out of Premiere.

Just stop use AME 25 and render directly from Premiere or AE.

You can still downgrade to AME 24 that is working great.
These are the only 2 solutions as adobe still not accept that there is a big problem with AME 25...

Same problem here... Since AME 25 i need 45min to render a simple story 1080x1920, H264 hardware encoding, just simple cuts, no effects....
Render time direct in premiere pro : less than 1 min

Render time in AME : 45min

W11 pro, Intel(R) Core(TM) i7-8700 CPU @ 3.20GHz, 64go RAM, RTX 4070 12go

Problem is from the update, same everytime... Not the configuration...

I've also experienced similar long render times recently (on AME 25.1). A 2 hour Premiere Pro sequence (no effects, just simple cuts and some cross dissolves) was taking 50 hours to render...fortunately I had the time to wait, so I just let it finish. Just now I was rendering a 45 min video that had an estimated 10 hour render time in AME, but then I had a brief power cut that interrupted everything, so I had to start over, and now the same video is now estimated at 1 hour. It's almost as if the computer reboot freed up some memory or something.

Bro' just render directly from premiere pro, u will save a lot of time, untill they don't accept that the AME 25 is full bugged, i stopped using it... Doing all my renders from the premiere export menu, it saves me hours and hours !
