How to Create a Photo Slideshow Video in Lightroom Classic

Photo slideshows are one of those things photographers keep reinventing. Every platform wants you to sign up for a subscription, upload your images to their servers, and hope the algorithm makes something passable. But if you’re already in Lightroom Classic with 60 edited wedding images ready to go, there’s a faster path sitting right there in the module panel you probably never click: the Slideshow module.

I’ve been using it as a quick delivery tool for clients — a polished MP4 they can play on any device, share with parents, put on the TV at an anniversary dinner. It’s not perfect, but knowing exactly where it ends is what makes it genuinely useful.

What the Slideshow Module Actually Gives You

Lightroom Classic has seven modules along the top bar — Library, Develop, Map, Book, Slideshow, Print, Web. Most photographers live in Library and Develop and basically pretend the others don’t exist. The Slideshow module is hiding something useful.

Switch to it and you’ll see your currently selected photos loaded as slides. The right panel has the controls you actually care about:

Slide duration and transitions. You set a global display time — how long each photo stays on screen — and a transition length. I use 3–4 seconds per photo with a 1.5-second crossfade. That pacing feels right for a relaxed gallery viewing experience. Transition options are limited (dissolves, wipes), but crossfade is all I ever actually need.

Background music. Under the Soundtrack section, you add an MP3 or AAC file from your local machine. Lightroom will either fit the slideshow length to the music track or you can set a manual duration and let the song cut at a fixed point. Fit to Music is what I use — it scales per-slide timing automatically so the slideshow ends cleanly with the last note of the song.

Identity plate. A text or logo overlay you can place on every slide — your studio name, a “Emma + Tom — October 2026” label. Either a branding touch or mildly distracting, depending on your taste. I leave it off for client delivery but put my logo on anything I post publicly.

Preview. Hit the Play button in the bottom panel and you get a real-time preview of the full slideshow — music, transitions, timing. Tweak the duration, press Play again. You can iterate in two or three minutes until it feels right.

Exporting as MP4

Hit the Export Video button in the bottom left of the Slideshow module. Three size options: 480p, 720p, and 1080p. Always pick 1080p. Pick a filename and destination, click OK.

For 60 photos at 3.5 seconds each with a 3.5-minute track, export takes around 2–3 minutes. The output is an H.264 MP4 — playable on every device, uploadable to any platform, no special software needed to watch it. File sizes land around 300–700MB for a full-length wedding slideshow.

For delivery: I either put the file in the client’s shared Dropbox folder, or I upload it as an unlisted YouTube video so they can watch it at full quality on their TV without downloading a 600MB file. Both work cleanly.

Where It Breaks Down

These aren’t edge cases — they’ll come up regularly, so it’s better to know now:

1080p ceiling. Output is capped at 1080p regardless of your source photos. For most clients watching on a phone or a 65-inch TV, this is completely fine. If someone specifically needs 4K video for a venue projector or broadcast use, Lightroom isn’t the tool.

Video clips can’t be included as slides. The Slideshow module only accepts still photos. MP4 video files — whether from your camera, from Burst2GIF burst animations, or from anything else in your catalog — cannot be dropped into the slide order. This is the single biggest limitation. If a client gallery has 60 photos and 8 burst MP4 animations, the slideshow will include the 60 photos and silently skip the 8 videos.

No smooth burst animation. You can set slide duration down to 0.1 seconds, but that doesn’t turn a burst sequence into a smooth animation. The rendering doesn’t hold up, and the result looks broken rather than fluid. For that specific workflow — turning burst photos into a smooth MP4 directly in Lightroom — a proper tool is required. The Lightroom video export guide covers exactly why the Slideshow module can’t bridge that gap.

Animated Moments: Keep Them Separate

The practical workflow I’ve settled on: Lightroom’s Slideshow module handles the full-set presentation video. Burst2GIF (full disclosure: I built this one) handles the individual animated moments from burst sequences. They serve different purposes and don’t need to be combined into a single deliverable.

The slideshow gives clients an easy way to experience all their photos with music — the kind of thing you watch on a couch with the volume up. The animated burst moments are a different beast entirely: they live inside the photo gallery between the still images, adding motion right at the moment it happened. More about that specific delivery approach in the wedding gallery guide.

The two deliverables complement each other. Couples who get both almost always mention both — the slideshow for the full emotional arc, the burst animations for the specific moments you couldn’t capture in a single frame.

Alternatives Worth Knowing

SmartSlides (Pic-Time built-in). If you use Pic-Time as your gallery platform, their built-in slideshow builder creates video from the photos already in your gallery. It syncs to music, looks professional, and requires nothing extra from Lightroom. If you’re already on Pic-Time, check this first before reinventing the wheel.

Animoto. More template variety and smoother motion effects than LR’s module. The trade-off: you’re uploading client photos to a third-party cloud service. For wedding clients who trust you with their memories, that’s worth thinking through.

iMovie. Free on Mac, significantly more capable. Drop in video clips alongside photos, control transitions per slide, adjust audio levels independently. The friction is that photos need to be exported from Lightroom first — you’re now managing a separate app and a folder of exported JPEGs. For a quick turnaround, that overhead adds up.

Premiere Pro / Final Cut Pro. Full video editors give you complete control: per-slide audio ducking, mixed video and photo timelines, 4K output, custom effects. For a photographer who doesn’t do regular video work, learning the timeline editor takes real time. Worth it if video delivery is a significant part of your business. Not worth it for an occasional wedding highlight.

When to Use It

Lightroom’s Slideshow module earns its place when a client specifically asks for a video and you want to deliver something polished without opening another application. Setup takes 10–15 minutes if you have a go-to template and a music track ready. The output is clean. It lives in software you already own.

It’s not a substitute for real video editing when you need more control. It’s not a replacement for burst animation workflows — that’s a separate problem requiring a separate tool. But for “something I can give clients alongside their gallery without adding an hour to my workflow,” it quietly does the job.
