how to put a video in slow mo on iphone

On an iPhone, you can put a video in slow motion either by recording in Slo‑Mo from the start or by editing an existing clip in the Photos app or iMovie, all with just a few taps. Here’s a simple, step‑by‑step guide plus a few extra tricks to make it look smooth and cinematic.

Use the built‑in Slo‑Mo camera

This is the easiest way if you haven’t recorded yet.

1. Open the Camera app on your iPhone.

2. Swipe the mode bar until you see Slo‑Mo , then tap it.

3. Tap the red Record button to start, then tap again to stop.

4. Open the Photos app, find your clip, and tap Edit if you want to tweak where the slow motion starts and ends.

In the editor, you’ll see a bar of vertical lines under the video; the dense lines mark the slow‑motion part and the sparse lines mark normal speed.

Slow down an existing video in Photos

If you already shot a normal‑speed video, you can still slow it down with simple editing.

1. Open Photos and select the video.
2. Tap Edit in the top‑right corner.

3. If it’s a Slo‑Mo clip, drag the two taller white lines in the timeline to control which section plays in slow motion and which stays normal speed.

4. For a regular video, many guides recommend using an editor like iMovie or a third‑party app (see next section) to change speed.

5. Tap Done to save your changes.

You can repeat this to fine‑tune the timing until the action looks exactly as dramatic as you want.

Use iMovie on iPhone for more control

iMovie (free from Apple) gives you a clear speed slider and works great for turning normal clips into slow‑motion shots.

1. Open iMovie and tap Create Project → Movie.

2. Choose the video you want, then tap Create Movie.

3. In the timeline, tap the clip so the editing tools appear.

4. Tap the Speed icon (looks like a little dial/speedometer).

5. Drag the slider to the left (toward the turtle icon) to slow the video; the further left, the slower it plays (e.g., 0.5×, 0.3×).

6. Tap Done , then use the share button to save the edited video back to Photos or share it to social apps.

This is handy when only one section of a video needs to be slowed down instead of the whole clip.

Adjust Slo‑Mo quality in Settings

If you want really smooth slow motion for future recordings, change the Slo‑Mo frame rate first.

• Go to Settings → Camera → Record Slo‑mo.

• Choose a higher frame rate, such as 1080p at 240 fps , if your model supports it.

• Higher fps gives smoother slow motion but uses more storage space per video.

This is useful when filming fast action like sports, pets running, or water splashes.

Try popular apps and social tools

If you’re editing for TikTok, Instagram, or similar, those apps and other editors can slow your video without much effort.

• Third‑party editors (like YouCam Video, Videoshop, Descript, and others) let you pick a clip, tap a Speed tool, and drag a slider to slow down part or all of the video.

• Social apps often include built‑in speed controls when you create or edit a reel or short, so you can match trends without leaving the app.

These tools also add extras like filters, subtitles, transitions, and music to make the slow‑mo moment stand out.

TL;DR:

• For fastest results, shoot directly in Slo‑Mo in the Camera app.
• To slow down an existing clip, edit it in Photos or iMovie and move the speed slider left.
• For advanced effects or social trends, use video‑editing or social apps with built‑in speed controls.
