Lightroom Classic 9.3 can only preview slideshow once before freezes or crashes

  • Updated 2 weeks ago

I have not used slideshow in a long time, so maybe this has been an issue for a while. I have a folder of 218 images in a collection, on the same hard drive with my other hundreds of thousands of images I use in Lightroom. The slideshow consists of mostly small jpegs, but also some raw NEF, and DNG files, maybe even a TIFF or two. Yesterday and today I was able to do edits to slideshow settings, run a few previews on only a few images and export that fine. I save my settings as a template.

 

Today I added some music, made and saved some changes to my template, etc. Then I tried to do a preview, all 218 images, maybe 5 songs. It prepared the images, it started playing fine, but after maybe 12 minutes, I decided to change music order. I tried to do another preview, it seemed to be preparing, but then never played it. I tried hitting play button, it again prepared previews, but did not play.

 

I quit LRC, which took a little while, then relaunched it, and it again did only one preview but would not play a second one. One time it just plain crashed. Another time it froze, giving me SBBOD.

 

I even restarted the computer, in case it was a memory issue, but it is still (mis)behaving the same way. Also, when I restarted the program, I noticed it had deleted my template for some reason- it just plain disappeared! I see it in my last backup, with settings from a few days ago, so I know it was saved, and I was able to make changes to it this evening. Why would Lightroom delete it? Am I doing something wrong here? Can LRC not handle a 21 minute slideshow of still images?

 

I have 32 GB of ram on my iMac 5K, 27-inch, Late 2015 iMac, so I don’t think that is the issue. Running High Sierra, 10.13.6. Any suggestions appreciated.

Perhaps not related as I didn't know that a slide show could include raw images. I always export the images in the best format for my target device: jpeg full quality, 4k resolution, sharpened for screen and then create the slide show from those images. Then the show has universal portability.

Though for one friend who has a HD (720) TV, I do a separate export at that resolution because it took 7 seconds to upscale each image before displaying it.

I don't know- the documentation I found on the Adobe site was pretty sparse. I could see it might choke on raw images, although doesn't Lightroom have a smaller jpeg in its catalog file? And it seemed to cache & start playing just fine after maybe 10 seconds, although I did not let it play more than halfway through. And why would it die on the second round? Now, after last relaunch of LRC, it won't even do 1 preview of the slideshow. Very frustrating.

I could export raw files as jpegs, it that was the issue, although then I would have to add them to catalog again, which would cause confusion with original files...

You can choose to "keep with original" then they will be along side the originals in the same folder and in the catalog. A little extra work to give them a unique keyword to select them for creating the album. This is why I put them in a separate folder.

Let's do a "once over" on your iMac to make sure the issue isn't a cache or corrupt application state: Download the free Onyx (https://www.titanium-software.fr/en/onyx.html), select the Onyx version for your OS, download, run it, reboot.

In Onyx run almost everything in the Maintenance tab, deselecting things you may not want deleted, like Launch Services . Hit the "Options" button across from "Internet" and check/deselect more stuff like Cookies & Other Site Data, Browser History, Form Values, (which are OFF by default), but make any other choices you want to keep. If you don’t know what something is, google it, or don’t run it, or ask me, then hit Run Tasks. After it's done it will ask for a reboot.

Also try to fix any directory damage by running Disk First Aid from Disk Utility: boot into Recovery Mode, (hold down Command-R when booting). When you're in Recovery Mode go to the Utilities menu and launch Disk Utility, say Repair Disk. When done go to Apple Menu for Startup disk and restart normally. 

If that doesn’t work try launching Lightroom from your other (admin or test) account, with a brand new catalog, as a test. Does it run OK? If it does it may be a corrupted preference in your Username/Library folder. To reset your LR preferences: 

1. Close Lightroom. 

2. Hold down [Alt/Opt]+[Shift] while restarting Lightroom. 

3. Overwrite the Preferences when prompted by the dialog. 

4. Close Lightroom. 

5. Restart Lightroom.  

Let me know if any of that helped!

Thanks Carlos- not sure if I will have time to all of that, as I need to work, and slideshow I need by tomorrow. Also, if I reset LR preferences, what will I lose?

Also, will post additional things & I have tried today, and results...

I tried selecting only the jpegs, but it still won’t play, but program has not frozen per se. It also won’t let me add more music- I have 4 songs selected. And when I went to Library mode, many of the selected images now have an exclamation mark in a black circle in the upper right corner, and the thumbnail is empty. But not all of those selected images, just some... If I click on the ones that still do display a thumbnail, they get the exclamation mark as well, but can still see thumbnail, and still see images fine in Loupe view.

I tried not using music, LRC prepared all the files, started playing, but stopped at number 6. Quit, restarted it, select 12, seems to work fine. Tried again, stopped at #2.

Also, I always set quality to draft, but after restart it always defaults to standard.

Tried to export 217 files as small jpegs, I got an error message that it could not do 103 of them, mostly raw files, but also some jpegs. When I went to a few of the missing the images, and hit Command + R, it finds them in the finder just fine.

I then optimized the catalog- previews grew from around 300 GB to 330 GB, lrcat shrank for 3.14 GB to 3.09 GB, lrcat-wal grew from 6.8 MB to 3.11 GB!

Tried exporting again, this time one file could not be saved, 201 could not be found!!!

Tried exporting just 7 jpegs, 5 could not be found!

Quit and restarted LRC again, was able to export all the images. Then I imported all new jpegs (only), remade my slideshow, was able prepare files and start preview, but when I stopped it and tried again, it again prepared files, but would not play a second time.

Resetting the Prefs doesn't lose you much, really, it's painless. Just browse the tabs and check everything's the way you want. 5 minutes.

Run Onyx/fix Directory Damage with Disk Utility! You may improve the issue (or not), but it will help the Mac overall.
