Ai noise reduction not working lightroom classic

[hotfix 30474]

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

[Alex and Amy]

I am getting the same thing here! Any resolution to this?

[SdeGat]

Not as far as I know. 😞 I spent some time with Adobe support and let them do stuff on my computer but got no improvement. Turning off GPU acceleration is the only thing that helps so far. 😕

this issue just appeared out of nowhere for me, still couldnt figure anything out to fix this

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!

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.

how do i know if I have a bayer file? What is the correct extension?

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

[adombrow]

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.

[Maria Isabel5EC5]

Wow, Anthony. Thanks a lot. Solved. I was looking for a solution here and other fora and did not find anything really useful. Your solution worked for me (at least at this moment).  I think this release the load of GPU of my computer, and all is going better.

[Sunny_worker0062]

I love you, Anthony!!! It works and you saved my life :))

[JettL]

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

You can find this under Preferences / Performance

[Claire27034065sm4s]

How do you clear your caches? 

[karim93234694]

I've been having issues with this for months now, even the Adobe tech that remoted into my computer couldn't figure it out, and you got it!!! Thank you so much, your advice was the only one on this entire thread that actually made Denoise start to work again for me!

[amber35345017svth]

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 

[SdeGat]

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

[Humza24888771sl9h]

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..

[SdeGat]

Could this be fixed in release 13.2 that was just made avalaible? 

[adventureous]

It seems you have to use Denoise before you go to PS. If I try Denoise after a file comes back from PS into LR as a tiff it will not work, the button and word "denoise" is sort of grayed out and you can't click it.  Denoise will work on Canon CR files. 

[SdeGat]

I have found that stopping the use of the graphics card in LrC solved the problem. 💁‍

And yes, my video drivers are always up to date. 

[Law_ren_ce]

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.

[SdeGat]

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) 

[Law_ren_ce]

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.

[SdeGat]

I agree on the randomness (or unpredictability). 😠

[ARNALDO37858144m3uy]

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 .

[SdeGat]

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

I'm on a Windows 11 computer.
