I have been using Lightroom classic for years. reacently I started looking into its slideshow capabilities. I have created a collection of around 80 photos. When I press Preview or Play it goes through preparing the slides. It is a very slow process. I left it and went to dinner and came back after 3 hours and it was only at Slide 25. I started the process multiple times, rebooted Lightroom, rebooted my iMac, ... Same process. Takes hours to prepare the slides. I have yet to complete one slideshow.
Thanks for reaching out. We are sorry about the trouble with Lightroom Classic. We are here to help!
Could you please confirm the version of Lightroom Classic along with the exact version of the operating system you are working on? Please specify the type of photos you are working on? Are you creating the slideshow from a collection with any missing images? Does this happen with all images/collections, or do any specific images behave similarly?
Have you tried any troubleshooting steps?
Please use images with uniform dimensions (only landscapes or portraits) in the slideshow as a test.
You can also try to clear the DynamicLink Manager (it handles video playback in Lightroom) by following these steps:
This did now help me, sorry. I have a slide show with 1000 slides, to put up on a set of large screens. In the "old" days I would hit play and within a minute the prep was complete. What is the status on a fix?
