Rendering is extremely slow since the 2025 update

I got the same problem too,  to me I started to get that problem from 2024 version.  

Dear Adobe. I liked your updated interface, really nice and convenient. But what's the trouble with optimization? The renderer of a simple video camera + screen recording lasting 3 hours is processed for 6+ hours. The graphics card is used by 20%. I enabled CUDA.

My system:
i9-11900k
RTX 4090
64 GB DDR4
+ some Samsung M2 SSDs

I haven't noticed such issues in version 24, but for some reason after new versions are released the older ones start to lag amazingly, which just makes me switch to them. I'm just thinking more and more, every day, about switching to DaVinci.

Do something about it, such a video with such settings should render no more than an hour. I'm not talking about After Effects optimization, no matter how many times I tried to use this product I always get some inadequate load on the processor, but not on the video card, no matter how many guides I watched, I tried to optimize for your products, but I always just waste my nerves, despite the fact that I've been using the license for several years.

For example stabilization in Boris Mocha is done in 5 seconds, the same work After Effects does 10 minutes.

By the way “crop”, which you added to “motion” does not work correctly, if you make crop inside, then you can not make rounding, I think there are some conflicts of functions, but this is just a small thing compared to the optimization.

I sincerely do not understand why you should suck the last drops of life out of the old “engine”, you know that the product is already just working from the last strength and is kept solely on the Adobe ecosystem. You're just forcing your loyal users to start using other products, and your market dominance will soon come to naught because of this negligent attitude. You look yourself, here people complain not with the cheapest “iron”, I can not imagine how your product works with people on weaker computers, if even here such problems. But why do optimization, which has been requested for years, when you can just make a nice new interface. This is some kind of spit in the face of Adobe users.

And I see recommendations for adjustment layers here, but don't you think it's funny that people have to figure it out themselves and find this thread to figure out what the problem is? You need to make a normal product and fix problems in time. Don't release raw versions. And once again, update your ancient engines of 30 years ago to modern ones. Otherwise, soon you will remain relevant only for Photoshop and Lightroom users.

I just upgraded my computer and had to install the latest version of Premiere 25.1.0 and I am having the same issue!    Crazy slow render times, or the system hanging completely, or an error.  This should NOT be happening in a supposedly upgraded version of the software!  Fortunately I only have one project that I have worked on in Premiere 2025; I will try to install an older version of Premiere and see if my rendering goes back to what it used to be.

With the exact same project and settings…

• Premiere 25 export time (real) <7 minutes
• Premiere 25.1 export (estimated) >7 hours

I've been using the same computer, cameras, and software for about 3 years.

I had the same issue with 25.1 several small slowdowns while working but the rendering times went up 200%. Tried restarting the reinstalling nothing. So I reinstalled 25 and with the 25.1 Media Encoder is working fine infact it maybe slightly faster than 25 version of media encoder.

Same problem here. On both computers (Mac Book Pro M2 MAX, 32 GB  + older iMac 2019) I installed AE 2025 and it's imposible export work. 1 hour for short easy animation etc. So crazy!

I have to look for downgrade, otherwise, they will beat me at work because the clients won't pay for that crazy times.    

I have also this problemen, also if i want to pre-render it take for a 20 mins video endless (after 45 mins premiere renderd 2%) 😱

Yep, one day rendering is fast the next day we are back to 1999 render speeds. Adobe you better figure this one out. You are going to lose a lot of people who don't have the luxry of waiting an hour for a 1 minute video to render. I had to go back to working in 2024 to address the render issue. I couldn't preview titles of my video either. Screen just goes black.
