Lightroom Classic Slideshow Export Hangs

  • 8
  • Problem
  • Updated 1 month ago
When I try to export a slideshow 720p or 1080p from LR Classic from my main catalogue the export hangs. But if I export from a seperate catalogue (containing one wedding) from either a separate mac or the same mac it works fine. 

I seem to have been having the same issue for a couple of years now and can't seem to find a fix for the main catalogue, which has meant me not doing slideshows for wedding clients during this time, which is a shame. 

Any thoughts?

It could be due to corruption in the LR Preferences file. The original Preferences file is carried over and updated on each LR upgrade so it could be the cause of your long-standing issue. Try resetting the LR Preferences file as outlined at the below link:

It appears a previous bug when using Portrait and Landscape images with Option> Zoom to Fill Frame checked is back (or was never fixed). Try unchecking that option and then restarting LR.

Same here. This is neither the cause nor the solution.

it's so frustrating as what should be a simple task is very flaky and unstable, with what seems like no help or support from Adobe. 

As a PROFESSIONAL photographer using PROFESSIONAL software I would expect better!!

One other thing to try. In the Library module select all of the image files to be used in the Slideshow. Go to menu Library> Previews> and select 'Build 1:1 Previews.' This fixed the issue with landscape and portrait images using 'Zoom to Fill Frame' checked so it may also fix your issue.

Matt Boadlesaid 892 images and the drive is a 2tb fusion with 128gb ssd portion
That is a long slideshow video! LR rendering video speeds are .5x to 2x. If your Slide Length + Crossfade is 7.5 sec. then your slideshow duration is 892 x 7.5 sec = 6,690 sec. = 111.5 min. = 1 hr. and 51.5 min. With a typical 1x processor rendering speed it's going to take about two hours or more to complete.

Dario Piovera saidMy problem is not solved: I tried again with 1 pictures, but LR hangs always at the same point:
You need to select at least two (2) image files to create a LR Slideshow video. Please close all applications and shut down and restart your system. Open LR, select two image files, and then rebuild 1:1 Previews as I outlined in my previous post. Try again. If that works try with about 50 image files selected.

Each video is a 1h5m video with 8 music tracks. I use the fit to music option so it’s always the same length no matter how many photos we use. ‘Normally’ it does export quicker than the mamouth 3 hours or so it took last night.

Try using the Adobe provide template named 'Simple' located in the 'Template Browser' panel on the left side of the screen. Do NOT change any of the settings.

Still three months later and adobe still don't bother to fix the issue. Who do I right to to see if they want to care or to find out if they are going to actually do something about the issue, or even just acknowledge it?

Come on Adobe. My loyalty is waining. Maybe I should just moved to Capture One as friend have recommended?

Close lightroom after it hangs. Open lightroom again. It will open up in the Slide show module. Press export video again. Now it works.... really weird issue. Does not matter if u have landscape or portrait.

I finally gave up and exported images only to Windows Media Player and made a slideshow that way... too bad. It's ridiculous that Lightroom is now a monthly subscription anyway and then 1/2 the time things don't even work. Can anyone out there recommend any other photo editing software? I'm ready to jump ship....
Thanks in advance.

Hi, I just would like to add a contribution... for what is worth!
I just bought an iMac Pro and, aside the disappointment of the general speed and the headaches to activate/deactivate my Lightroom Classic CC v.8, I also incurred in the famous (or infamous) slideshow export.
I have tried several scenarios (only landscapes, adding portraits, removing stars, adding and removing "zoom and pan"...)  and I ended up finding that if the transition time was 2 seconds, the system was hanging, if I modified this (i.e. 1.9 sec or 2.1 sec) it worked flawlessly.
But I must add that on my NoteBook Pro (same OSX, same Lightroom Classic CC v.8, same catalog etc.) the export worked perfectly EVEN with the 2 sec transition time.
Now, the only REAL question is why Adobe is not fixing this bug (as Matt Boadle said)
Let's keep on searching...

The only solution I found was: 1. Make a copy of the presentation in LR. 2. Export photos from the presentation to jpg 3. Upload to the copy of the jpg photo presentation. 4. Convert to 1080p. This does not solve the problem in LR, but allows you to make a presentation.
The second solution is quite ridiculous: 1. Install the program to dump the image and sound from the screen in the form of a movie. 2. Start recording in the program to dump from the movie screen. 3. Turn on Play in the presentation in LR 4. After recording, set the beginning and end of the movie. The conversion of the presentation will take a dozen times less time than with normal conversion. Why is it so, I have no idea.

Many thanks, Marcin.

The first approach (exporting to JPEG) is the only one that has worked in my case. Absolutely exhausted of trying one and another fix. 

After making all the development process in your travel shots, the main point is to share your work with your family in a video. It's a shame that Adobe had not sort out such an old problem. Really discouraging.

This is still a bug in LR Classic 8.3.1. Apart from being unable to export slideshows with photos, it also can't export any slideshows involving MP4 videos in any of the 4 video formats offered (from lo res to 1080p), even if it's one short video (without any other videos or photos), despite being able to display these slideshows via the Preview, Quick Slideshow or Play buttons. At the moment, my workaround on macOS Mojave is to either:
  1. use iMovie to create a slideshow (which can take longer), or
  2. use Mojave's built-in screen recording feature (Shift-Cmd-5) to record the slideshow preview (so I don't have to insert captions etc in iMovie), and then import it into iMovie to add an audio track (if required).
Really, it's time for Adobe to sort out LR Slideshow module, no?..

I was having this problem.  I tried exporting with various settings and it kept getting hung up at the same spot.  I realized that some of my images were TIFFs, and the first one was about the spot where I got stuck.  I exported all the images as jpgs and reimported the jpgs into the slide show module.  I had no problem exporting the slide show once I did that.

I'm a big slideshow export user, and this problem only started happening recently after a few months away from the work.  Looks like I've got the same problem everyone here is reporting.  Now I have the added experience of having adobe support "fix" it, only to have wasted 2 hours, wiped my preferences, got a new install of lightroom, messed with my monitor settings, and treated me like I didn't know a thing about what I'm doing.  Terrible customer care on this.  

Adobe - I expect my subscription fee refund until you have fixed this.
