Treat each photo as a clip and change the image on the beat. A 30-second slideshow at 120 BPM cutting on every second beat needs about 30 images; give each one a slow push in or drift so the frame is never completely static, and keep the crop consistent so faces and products do not jump between shots.

A slideshow is not a lesser reel. It is a reel whose clips happen to be one frame long, and once you think of it that way every rule about pacing, cutting and grading applies unchanged, which is good news, because photos are the footage almost everybody already has.

## Who this is actually for

- **Anyone with an archive and no video.** Products, property, food, travel, portfolios, before-and-afters.
- **Accounts that need volume** and cannot film weekly: a slideshow is an evening's work from a folder that already exists.
- **Products photographed properly once.** Ten good product shots make a better reel than ten shaky clips of the same thing.
- **Anything with a result to show.** Before-and-after is the strongest slideshow shape there is, because the format is inherently comparative.

## How many photos

The same arithmetic as any other beat-matched edit: the track sets the count, not the pile of images.

| Length | Cut density | Photos needed | Each on screen for |
|---|---|---|---|
| 15s at 120 BPM | Every 2nd beat | ~15 | 1.0s |
| 30s at 120 BPM | Every 2nd beat | ~30 | 1.0s |
| 30s at 120 BPM | Every 4th beat | ~15 | 2.0s |
| 30s at 90 BPM | Every 2nd beat | ~22 | 1.3s |

Photos need longer on screen than video does. A moving clip is legible in a third of a second because the motion tells you what you are looking at; a still needs closer to a second. If you have fifteen images and want thirty seconds, drop to every fourth beat rather than repeating everything twice.

This is the one place slideshows differ meaningfully from footage-based edits. [How many cuts a reel should have](https://easyreels.io/blog/how-many-cuts-in-a-reel) has the general arithmetic; for stills, take the slower option in every case.

## Why stills need movement

A completely static frame for a full second reads as a stalled video. The fix is small and it is the difference between a slideshow and a gallery: give every image a slow push in, pull out or drift across, at a rate slow enough that you would not notice it if you were not looking for it.

- **Around 3–5% of the frame over the shot.** Enough to feel alive, not enough to read as a zoom.
- **Alternate direction.** Push in, then out, then across. Thirty identical pushes is its own kind of monotony.
- **Move toward the subject.** Push in on the thing the photo is about, not on empty space.
- **Never zoom on a low-resolution image.** You are enlarging pixels, and compression will find them.

## Cropping, and the jump problem

Photos arrive in every shape there is and the reel is 9:16, so every image is being cropped. Done carelessly, the subject lands in a different place in each frame and the sequence flickers.

1. **Pick one anchor and keep it.** If the subject sits at the upper third in image one, put it there in all thirty.
2. **Crop to fill, never letterbox.** Black bars top and bottom on a phone read as a mistake, not a style.
3. **Landscape photos are the hard case.** Cropping a wide shot to 9:16 keeps a quarter of it, so choose which quarter deliberately, or use the image as a slow horizontal drift across the full width instead.
4. **Keep text and faces out of the interface zones**, roughly the bottom 420px and the right 180px: [vertical video size and the safe area](https://easyreels.io/blog/vertical-video-dimensions).

## One grade over everything

Photos from different days, cameras and lighting look like photos from different days, cameras and lighting. A single grade applied across the whole video is what turns a mixed archive into something that reads as one piece, and it matters more for slideshows than for footage, because a still gives the viewer time to notice that this image is cooler than the last one.

Apply it to the whole sequence rather than image by image, at a moderate intensity. [Colour grading short video](https://easyreels.io/blog/color-grading-short-video) covers how far to take it; on a slideshow, slightly further than you would on video is usually right, because the unification is doing real work.

## Shapes that work

| Shape | Structure | Best for |
|---|---|---|
| Before and after | Alternate, then hold on the after | Renovation, fitness, restoration, design |
| The process | Chronological, ending on the finished thing | Making, cooking, building |
| The catalogue | One product per beat, same crop | Ecommerce, collections, menus |
| The place | Wide, detail, wide, detail | Property, travel, hospitality |
| The list | One image per point, with text | Educational, tips, comparisons |

In every case the last image should hold longer than the rest. Delete the final cut and let the closing frame sit for two or three beats. It gives the video an ending rather than a stop, and it is the frame people are looking at when they decide whether to follow.

## Text, and the cover

Slideshows carry text better than footage does, because the background is not moving. One fixed hook line at the top for the first few seconds, and short labels per image if the shape calls for it, in the same typeface and position every time: [reusable text overlays](https://easyreels.io/blog/reusable-text-overlays).

And choose the cover deliberately. On a slideshow the first image is doing double duty as the scroll-stopper and the grid tile, which makes it the most important of the thirty. [Reel covers](https://easyreels.io/blog/reel-cover-and-thumbnail) covers the crop that survives a grid.

## Mixing stills and video

The best version of this is usually not a pure slideshow. A few clips among the stills gives the edit texture, and a few stills among the clips gives it punctuation, because the eye reads the change of medium as a deliberate beat.

Mechanically there is nothing to it, because a photo and a clip occupy a cut slot identically. In [Easy Reels](https://easyreels.io/) images and video sit in the same media library and a template pulls from either, so a folder of thirty photos and a track is a finished 9:16 in one generation. Which is the practical point of all of this: an archive you already own is a month of posts you have not made yet. It is the same argument as [turning old footage into new reels](https://easyreels.io/blog/repurpose-footage-you-already-have), applied to the photos folder.
