Lightroom Classic

I updated to LrC 15.5 a few hours ago.  Since then LrC has problems with video files.  The first problem I noticed was that when I tried to synchronize a folder that had two new video files.  After a couple of minutes I got the error message “An unknown error occurred while reading the video file. (2)”.  I had just completed those files with DaVinci Resolve so I went back and produced the same files again to check if DR had made an error.  When I tried again with the new files but got the same errors.  I was able to play both videos without any issue using VLC Media Player, so they seem to be OK.  I then shutdown LrC and did a backup including optimizing the catalog, and then restarted it to see if that made any difference, but same error.  Then I started looking at other videos that were already in LrC and found that when browsing them in the Library module, most of them pop up a message “There was an error working with the video”.  They will not play in LrC but work fine with VLC Med

In the Library, I’m trying to play video in Lightroom Classic with the latest updates. I receive an error saying, “There was an error working with the video”. It does this to all videos. I’ve restarted my computer and closed the program and restarted more than once. If I remove the file from Lightroom then try to import it back it says, “Preview unavailable for this file.” When I click import it says “An unknown error occurred while reading the video file (1).” Some videos in other folders work. In more than one folder they do not play. This problem began after I updated the last Lightroom Classic to 15.5 release.

Adobe Lightroom Classic 15.5 import problem on Windows 11Hi Adobe team and Lightroom Classic users,I’m experiencing a serious import problem with Lightroom Classic 15.5 on my Windows PC, and this only started happening recently.System: OS: Windows 11 Pro 25H2 Lightroom Classic: 15.5 Catalog: Tested with both my current catalog and an older catalog Photos: Sony ARW RAW files Import: Using Add Storage: Tested from different physical drives Problem:Lightroom can see and read the photos normally in the Import dialog. For example, I can select 1,446 ARW files and Lightroom correctly displays all the thumbnails and recognizes the files.However, when I click Import, the import progress bar only runs for around 2 to 3 seconds and then disappears.After that, Lightroom returns to the Library and shows:All Photographs: 0None of the photos are added to the catalog.This is happening even when I try importing only a few photos.What I have already tried: Tested the original photo drive Mo

I upload Iphone photos from my phone to the LR Cloud using the LR Phone App. I then go into LrC and let them sync back down to my desktop. No problem so far. Once the photo files are safely on my desktop I unsync from the cloud. I then assign keywords and other metatdata whilst in LrC. My next step is to sync the photos back to the Cloud as smart previews. I do this by dragging the photos to an already synced collection. However, they don't sync. They try for about 3 mins and then they remove themselves from the synced collection. However, they still appear under "All synced Photos" and the blue sync ball continues to spin. However, when I remove these photos from "All synced photos" the green tick immediately appears. To sync these photos I have to restart LrC and then again drag the photos the the synced collection. They then sync properly in seconds. I should add it makes no difference whether I delete smart previews, delete the deleted original files from the deleted folder, save t

This behavior occured in the last week, after the latest upadate of Lightroom Classic.  Other approaches yielded the same deletion of the selected image.

I've tried all the google suggestions, but cannot get the menu headings 'FILE EDIT ..etc .' in Lightroom Classic.    Need this to follow instructions in an Adobe video to fix another problem.

Have been having a lot of crashes with LRc 15.4.1 for a week or so. Currently the situation is so bad, that moving from library to dev the app crashes every time. I’ve been sending a lot of crash reports. I’ve also tested multiple files from different cameras over past 20 years, the issue stays.I’ve also tested downgrading LRc, issue doesn’t go away. I also tested the other Lightroom, Photoshop, Bridge and Bridge (beta) - all crashing equally the same, when changing to dev/edit or in case of bridge an ps, just opening any raw file. This suggests that the problem is somewhere in Adobe shared runtime stack that is used by all of the apps. I also repaired Creative Cloud installation, no help. Files can be opened just fine in any other capable app. I created new catalogs to see if it was catalog corruption, but it is not. I have gone through all the usual Windows error checkings, sfc, dism, chkdsk, even the memory check. no problems there. All my other apps and even games work fine. Window

Please advise: When I try to start LrC 2025 i receive the Error message "The Lightroom Catalog 'file name' is corrupt and cannot be used until it is repaired."  LrC will not open when I double click to start. I also have a permanent banner on my screen stating "Lightroom - Opening Catalog: File Name.psd"  This is on the Windows platform, Windows 11. I have tried re-booting, re-installing LrC, but nothing works.  NOTE: I'm an experienced LrC user, and an inexperienced PS user. Before this happened, I tried to save a file from PS, then import it to LrC after deleting a previous version of the same file.  Please help.

Merge to HDR in LrC 15.3 is stalling (beach ball) or not responding.  I frequently merge HDR images for Real Estate photos and today, after updating to LrC 15.3 I had to Force Quit from LrC multiple times to regain control of LrC.  I stacked my bracketed shots and used CTRL+H to merge.  LrC did process a couple before stalling.  After multiple attempts resulting in Force Closing, I tried using the menu commands, no change.  I then uninstalled 15.3 and reinstalled a fresh copy of 15.3 and the HDR problem continued.  Finally I uninstalled 15.3 and downgraded to 15.2.1 and the Merge to HDR function worked as expected.  

Lightroom Classic 14.5.2 works perfectly on the same Windows 11 PC, but the latest 15.x version won't launch after installation. The program attempts to load for 3 seconds. No error message appears. The program shows up in Task Manager.Neither the latest NVIDIA driver nor the startup checks I’ve performed so far have resolved the issue. The fact that the latest version of Photoshop works further suggests that this isn’t a fundamental problem with Creative Cloud or my computer.

I posted about this before, my post was deleted with no explanation. I was not abusive in any way shape or form, so I have no idea why...but I will have another go and see if someone can help. LRC will not cull. I start the cull, and within a minute it shuts the programme down. It does not matter if it is a big batch of 3000 images or a small batch of 100, it still crashes. I have done a preference reset, uninstall/reinstall, checked my graphics card is setup correctly for studio and latest software. Nothing has made a difference. My system info is below. I need to know what is wrong, i dont want to have to fork out for a new system and find the same issue. Lightroom Classic version: 15.5 [ 202607291506-b8869fa7 ]License: Creative CloudLanguage setting: enOperating system: Windows 11 - Home Premium EditionVersion: 11.0.26200Application architecture: x64System architecture: x64Logical processor count: 12Processor speed: 2.6GHzSqLite Version: 3.36.0Adobe GSDK Version: 1.4.0.213CPU Utilis

Since the most recent Camera Raw update, all CR3 thumbnails show as purple lines on MacBook Air. Tried trashing and reinstalling Camera Raw and deleting a Mac thumbnail file in the library, but no change. 

LRC: 13.5.1Windows 11Lightroom has been really slow for me, and I was sure that facial recognition was turned off, but today I was scanning some photos that had group pictures, and LRC is still recognizing faces when I’ve explicitly turned it off. Note that it was turned off before this screen capture and has been turned off as long as I can remember, but LRC is clearly still doing it. How can I stop this? I don’t want LRC to recognize faces. I don’t want it, don’t need it, and it’s taking computer resources and slowing down my work. Thanks  NB: I am not upgrading to the newest version because it is incompatible with my Fuji GFX100 due to LRC’s native tethering causing issues. Thanks

I’m having an issue with the Pixieset Lightroom Classic plugin and need help recovering my published photo associations.My normal workflow is to use separate Lightroom Classic catalogs for different clients. From each catalog, I go to Publish Services → Pixieset, create/select the appropriate Pixieset collection and Highlights set, drag photos from my Lightroom Library into the set, and publish them.Until recently, when I opened one of my Lightroom catalogs and accessed Pixieset under Publish Services, my existing Pixieset collections would appear with the photos already associated with their corresponding sets.Something changed yesterday. Now the collection names and Highlights sets still appear in Lightroom, but they show 0 photos. The actual photos and galleries are still completely intact and visible on my Pixieset account.The behavior is also catalog-dependent: when I open a catalog containing the photos originally associated with a particular collection, those photos can still ap

When I try to import picture files, I get a popup for assisted culling that locks the application. I need to go to task manager to shut down the application.   I turned off assisted culling under catalog settings, but this does not correct the issue. Is anybody else experiencing this issue. I cannot import new files!  

When I attempt to open more than one image in an outside editor (photoshop, evoto, etc), from the library module, select all images and then right click, and select edit in, the dialog box about selecting file type appears, however only the active image is copied as a TIFF and opened. I’ve tried deselecting all then reselecting, but no matter what there is an active image and that is the only one that opens. 

Installed this and my tethered camera setup no longer works.  It appears to work as before, but no images are transferred.  Canon R1, Windows 11.  Anyone else having tethering issues?

Hi everyone,while Adobe seems wants to use all its energies to build a software to modify the reality with the AI (90% of the advertisements – email, websites, social networks only promote the AI’s features to eliminate people or objects, change the colours, etc.) I’m impressed by the partnership between the most important American news agency ‘Associated Press’ (AP) and the Danish company Capture One.What do you think about it?It’s not about the possibility to use or not use the AI, It’s about the direction that Adobe decided to give to the Photography pushing people to use the AI more and more massively. All the best,eliano
