The playback settings don’t apply to exported PDF slideshows. The slide duration and fade transition are fixed in PDF slideshows.
- In the Playback panel of the Slideshow module, make sure that Slide Duration is selected. Then, adjust the sliders or enter a value for the following options:
Slide Length
Sets the time (in seconds) that each photo is displayed.
Crossfades
Sets the time (in seconds) of the fade transition between slides.
- To create a transitional fade to a solid color between slides, select the Fades Color option, and then click the color box and choose a color from the pop-up window.
You can add a solid-colored slide at the beginning and end of your slide show for a gradual transition into and out of the presentation. You can display your identity plate on these slides.
-
Click the color box to specify a slide color from the pop-up window.
Select Add Identity Plate to display your identity plate on the slide. By default, the identity plate is white.
To change the color of the identity plate, select Override Color and then click the color box and choose a new color from the pop-up window.
To adjust the size of the identity plate, drag the Scale slider or type in a value.
Lightroom Classic can play any .mp3, .m4a, or .m4b music file as a soundtrack to a slideshow. Music plays as the slideshow is viewed from within Lightroom Classic or exported as a video. Music does not play in exported PDF slideshows.
Selecting Random Order plays your slides in random order when you play the slideshow in Lightroom Classic or export to video.
Note:
Deselecting this option restores the slides to the original order visible in the Filmstrip at the bottom. To change the order of your photos when you play the slideshow manually, simply drag and arrange your photos within the Filmstrip.

An impromptu slideshow is a full-screen slide show you can quickly play from any Lightroom Classic module. The impromptu slideshow uses the current template and settings in the Slideshow module.
You can export a slideshow as a PDF file so that you can view it on other computers. PDF slideshow transitions work when viewed using Adobe Acrobat or the free Adobe Reader. Exported PDF slideshows don’t include music, randomized images, or the duration settings you specify in Lightroom Classic.

Quality
Renders each slide at a specified JPEG quality setting. Lower quality slides yield a smaller slide show file size. Drag the Quality slider or enter a numeric value from 0 to 100 (with 100 representing the highest quality, and 0 representing the lowest).
Note: Photos are embedded with sRGB profiles.
Width and Height
Specify the pixel dimensions for the slideshow. Lightroom Classic resizes the slides to fit within the dimensions without cropping or changing the slide’s aspect ratio. The pixel dimensions of your computer display are the default size.
You can export a slideshow as a series of JPEG files that you can share with clients or other people. Each JPEG file includes the slide’s layout, background, and cell options. No transitions or playback options are exported.
You can export a slideshow as a video file that you can watch on other computers. Lightroom Classic saves video slideshows as H.264 MPEG-4 files complete with slide layout, soundtrack, and other playback options. The exported video is compatible with Adobe Media Player, Apple Quicktime, and Windows Media Player 12.
