Suddenly the ai noise reduction in lightroom classic does not work, what is wrong?

macOS

Correct answer JohanElzenga

Finally some useful info. That sounds like Lightroom might not have permissions to write to the folder, or perhaps the drive is almost full. Denoise creates a new file, so Lightroom needs to be able to write that file to disk. The error suggests that it can't for some reason.

Dear All unfortunately the possibility of Noise Reduction doesn't work . Everytime it goes in crash . What could be the solution ? Maybe a different set- up ... but where ? Thank you for your suggestions .

I fixed that issue on my computer by turning off GPU performance enhancer.

I'm on a Windows 11 computer.

I got the same problem. But I had a solution.

I did a AI NR batch of about 91 photos on my AMD workstation with RTX 3060 GPU and excellent specs and plenty of space on SSD and up to date Studio Driver. But six photos got listed in a pop up with that dreaded "unknow error - denoise not applied"

I started disabling GPU, removing a config film of the GPU, restarting LR... nothing helped. The error kept popping up.

Then I made a virtual copy of one of the photos to toy with it and see if things change. I removed the healing brushes. No effect. Then I did a complete reset on the virtual copy and then applied AI NR... et voila it worked. It applied it without any error pop up. Now I had my fingers crossed that it would do the same to the original file.... I first copied all the settings and adjustments made to it.... reset the photo.... and then paste the setting into it. And succes. It did. So now I did this process for the six listed in the error and it was fine. It's quite ridiculous and I don't understand what I did, but it worked. But its going to be a pain in the ass if it's going to be a way longer list of photos I need to manually reset & copy/paste their settings.

Adobe get it together.

My 2 cents.

I haven't had the problem since disabling my GPU. 💁‍

I also have problems with the simple crop tool with the GPU enabled.

(And, yes, I always have updated drivers for my RTX card)

In my case, disabling the GPU had no impact. I guess there are multiple reasons why the error is.... unknown.

I doubt my GPU had problems with six out of 91 photos. It's very random, those photos had no special edits applied to them.

I don't appreciate randomness. Not in this context.

When i try and denoise i get this message. Driver timed out. Brand new gateway adm computer with nothing on it. Raw files. I've uninstalled lightroom and re installed it. Installed the latest "adrenaline" driver from ADM.

Any suggestions?

Thank you

Looks like many of us have had similar problems with denoise and yet no solution in sight. 😕😕

Same, it started like a week ago now I think. I click "Denoise" let it run, I click apply let it load. And bam it says "There was an error writing the file".. Not sure what to do. I've restarted it and my computer a couple times. Never came across this problem..

I increased my cache size a couple of GB - then cleared both caches - works again

You can find this under Preferences / Performance

How do you clear your caches?

It kept giving me the same message.. I tried resetting Lightroom with no success BUT what did work for me was going into Adobe Lightroom 'Preferences'. Down to "Performance". Then under Use Graphics Processor, I selected Custom instead of Auto and Checked off the first 2 boxes ("use GPU for display" and "use GPU for image processing").
That works

Thank you! It worked for me with a slight difference. After I clicked on Custom, the first two boxes you referred to were grayed out, so I just restarted. It works now.

I have another issue. I took a number of photos on my iPhone 14 Pro Max using the 48 MP ProRaw setting and then imported them to Lightroom as ".DNG" files. However, when I went into Lightroom I was unable to use the Denise AI to remove noise. When will Adobe make this available to iPhone photos? Also, I noticed the Shift-Double Click sets the White Point but does not when applied to setting the Black Point. Why? Many thanks!

By @Lawrier

AI Denoise only for standard (not compressed) RAW, either Bayer, or FUji X. DNG would have to be full Adobe spec (if). When will Adobe expanded use?? Not for us common users to know.

Shift-Double Clcik Black Point. should work. Try again, LrC can be pickey at your mouse clicks.

I am having a somewhat similar problem. Yesterday, I was able to use the AI Denoise feature on several pics. Today, I have selected 3 pictures to denoise. It doesn't complete the process with any of them. I select a picture, click the denoise option, look at the before and after comparison, select "enhance", and wait. The little wheel spins, indicating the process is running, and after a minute or two, I get a grey screen saying "No photo selected".

I have exactly the same problem and it is becoming a frustration.

It was working for long time but unexpectedly it stopped working a few weeks ago under LRC v12. After updating LRC to v13 the issue persists. I also tried to uninstall LRC completelly but the problem persists.

There is no error message that can help tracking the issue. Is there any way to get logs from LRC that could help understanding the issue?

PS: Running on Macbook pro M2 32GB RAM and plenty of hard drive space.

Same issue for me on the same computer (2023 mbp m2 max 14 with 32gb ram). The file(s) will only show up after restarting Lightroom, and I'm not going to restart LRC everytime I want to use the AI denoise feature.

Similar problem here except it won't even start as Denoise is trying to save with the same filename.

And then offers to save as .TXT

Something's wrong...

I restarted Lightroom and it started to work properly. Not sure what happened.

Well I push the "Remove Noise" button. Then the program starts to work. But after a while it stops and a notice comes up that says "an error occurred while writing the file" (translated from swedish) and it hasn't done any noise reduction in the image

Hello Johan! The issue was that the new files were too large and it caused my external hard disk to run out of space. I appreciate your assistance, but it would be helpful if you could refrain from being rude ("Finally some useful info"). I'm trying my best to explain the situation even though I'm not completely fluent in both the language and the program.

Hi! Yes, in the middle of editing a wedding( i have edited over 1000 images) the new "Remove Noise" feature suddenly won't work... I haven't changed anything, it's still NEF raw files. I have tried uninstalling Lightroom classic and it is the latest version. Nevertheless, the problem remains.

Again: explain "won't work". That can mean anything.
