Very fast slideshow of 1000+ photos

[ETThompson]

Hi

I want to create a slideshow that I got the idea for while scrolling very fast through my 1000+ photos from a recent trip to Rome in Lightroom Classic.  With the arrow key held down it took about 30 seconds to go from beginning to end, and I thought that would be a cool and interesting way to share "all" of my photos.  Using an online time calculator, it looks like each frame would be about 25 milliseconds.

Is there a way to do this in LrC?  It seems like the regular slideshow time per slide only goes down to 1 second.  Is that the limit?  

If it's not do-able in LrC, is there another (Mac based ideally) app that can?  Ideally free, but not required - though I'm not sure I'd spend a ton of money on it.

Thanks for any suggestions you can give.

There is a workaround somewhere where you hack a configuration file to adjust the frame rate of a Lightroom Classic slide show. People used it to export basic time lapses from Lightroom. If you want to try that, you’ll probably have to do a web search for it. I’m not sure if it still works.

But it might be easier to export all of the images into a folder and string them together in any video editor. Because you use a Mac, for many years your Mac has already included a free app that can do this, QuickTime Player:

1. In Lightroom Classic, export all of the edited images to a folder in a common image format such as JPEG. Be sure to use the file renaming feature to add a sequence number to the beginning of each image to keep them in the order you want when sorted by Name. 

2. Open QuickTime Player. 

3. Choose File > Open Image Sequence. 

3. In the Open dialog box that appears, go to the folder containing the still images you exported from Lightroom Classic. 

4. Choose Edit > Select All, or press that command’s keyboard shortcut. 

5. Click Choose Media. 

6. A dialog box appears with video options such as Resolution and Frame Rate. Set it the way you want. 

7. Click Open. QuickTime Player creates a new video where each still image becomes one frame. So if you selected 30 frames per second, each still image appears for 1/30th of a second. 

8. Save the video. 

If you want more control over the frame rate or other video settings, you can instead use a video editor such as iMovie, Adobe Premiere Pro, or Apple Final Cut Pro. Most video editing apps have a similar feature where you can point it to a folder containing a numbered sequence of still images and it will assemble them into a video on a timeline. In there you can customize how fast it plays, by altering the still image durations or the timeline’s playback speed or frame rate.
