# A slideshow maker with music that changes on the beat

Add a song and your photos. Each picture arrives exactly on a beat, with a slow zoom to keep it moving, and you export a video ready to share or play on a TV.

To make a slideshow with music, add your song and your photos together: the tool finds the song’s beats and changes to the next photo exactly on one, every two beats to start with. Press **Export video** and you have a photo video in which the pictures move with the music instead of drifting across it at a fixed pace.

That timing is what separates a slideshow people watch from one they sit through. A photo that appears on a downbeat feels intentional; the same photo arriving half a beat late feels like a mistake, even if nobody can say why. **Slow zoom on photos** adds a gentle push in or out while each picture is on screen, and **Transitions** decides how one photo gives way to the next.

Your photos and music stay on your device; nothing is uploaded and there is no watermark. Need the tempo first? The [BPM finder](https://sync.video/bpm-finder) reads it from the song, and [tap tempo](https://sync.video/tap-tempo) works when the music is playing elsewhere. For video clips rather than photos, use [beat sync](https://sync.video/beat-sync).

A beat grid: the song’s beats (thin lines) and bars (thick lines) found from its loud attacks, with cuts placed on them.

## How to make a photo slideshow with music

1. ### Add the song and the photos
Drop them onto **Drop a song and your photos**, or press **Choose files**. JPEG, PNG, WebP and iPhone HEIC photos work; **Add photos** brings in more. Then press **Make the beat video**.
2. ### Set the pace
The **Cut style** starts at **Every 2 beats**. Choose **Every bar** for a calmer show or **Every beat** for a quick one; **Follow the energy** speeds up in the chorus.
3. ### Order and frame the photos
Select a photo and press **Move earlier** or **Move later** to reorder it, or **Remove** it. Under **More options**, **Fit** chooses **Fill the frame** or **Whole picture**, and **Slow zoom on photos** turns the movement on or off.
4. ### Pick the shape and length
Set the **Shape**: 9:16 for phones, 1:1 for feeds, 16:9 for a TV or YouTube. Choose how much of the song to use under **Song part** (15 s, 30 s, 1 min or All) and where it **Starts at**.
5. ### Export video
Press **Export video**, then **Download video**. On a phone, Share saves it to your photos.

## How long each photo stays on screen

The length of each photo comes from the song, not from a seconds setting. With **Every 2 beats**, a song at 120 BPM shows each photo for one second; at 90 BPM, for 1.33 seconds. That is the trick: the rhythm you hear decides the rhythm you see.

__Seconds per photo at common tempos__
| Tempo   | \*\*Every beat\*\* | \*\*Every 2 beats\*\* | \*\*Every bar\*\* (4 beats) |
| ------- | ------------------ | --------------------- | --------------------------- |
| 80 BPM  | 0.75 s             | 1.5 s                 | 3 s                         |
| 100 BPM | 0.6 s              | 1.2 s                 | 2.4 s                       |
| 120 BPM | 0.5 s              | 1 s                   | 2 s                         |
| 140 BPM | 0.43 s             | 0.86 s                | 1.7 s                       |

Under a second per photo suits a lively reel of many pictures. For a birthday, a wedding or a memorial, where people want time to look at each face, **Every bar** with a slower song is kinder. If you have fewer photos than the song needs, they repeat in order; add more, or shorten the **Song part**.

## Making photos feel alive

### Slow zoom

**Slow zoom on photos** moves gently in or out across each photo while it is on screen, so a still picture has some life. It is turned off automatically if your device asks for reduced motion.

### Transitions on the beat

* **Cut** is crisp and modern; it relies entirely on the beat for its punch.
* **Fade** softens the change, good for gentle songs.
* **Flash** and **Zoom** add energy on strong beats.
* **Slide** pushes the next photo in from the side.
* **Auto** chooses for each change: soft fades in quiet passages, a flash where a drop hits.

### Portrait and landscape photos together

Phone pictures are often a mix of tall and wide. **Fill the frame** crops each one to the shape you chose, which looks bold but can cut off heads in a group shot; **Whole picture** shows every photo complete with plain bars beside it. Try both on the preview.

## Music, copyright and ending well

Use any song file you have: MP3, M4A, WAV, or the soundtrack of a video. If you plan to post the slideshow publicly, make sure you have the right to use the song: a track you bought is usually for listening, not for publishing. Royalty-free music libraries and the music offered inside some social apps are the safer route for public posts.

Start the **Song part** where the music gets going, so the first photo lands on a real beat, and turn on **Fade out the music** so the show ends gently instead of mid-phrase. If the music needs to go onto a finished video rather than photos, [add audio to a video](https://sync.video/add-audio-to-video) does that.

## Slideshow with music questions

### How many photos can I use?

As many as your device handles comfortably; a few dozen is typical. The song decides how many are shown: a one-minute song at **Every 2 beats** and 120 BPM shows 60 photos, and fewer photos simply repeat.

### Can I mix photos and video clips?

Yes. Clips and photos can be added together, and each takes its turn on the beat.

### Can I choose how long each photo shows?

Indirectly, through the song and the **Cut style**: every beat, every two beats or every bar. That keeps every change on the music.

### Will the slideshow play on a TV?

Choose the 16:9 **Shape** and export an MP4; most TVs and streaming sticks play it from a USB stick or a phone cast.

### Do iPhone HEIC photos work?

Yes. Photos your browser can’t show directly are converted on your device first.

### Is there a watermark?

No watermark and no account. The photos and the song stay on your device.
