# Smart Auto-Cut

> Automatically cut idle moments — pauses, loading screens, and stretches with no mouse or keyboard activity — for tighter videos.

Section: Help Center › Advanced Editing

AI narration is usually shorter than the time you spent recording. If the video keeps moments where nothing happens — an idle cursor, a page loading — viewers sit through awkward silences. **Smart Auto-Cut** finds those idle moments and cuts them for you.

## When you create a project

When the **AI Script Writer** prepares your script, Smart Auto-Cut is on by default and removes long pauses from each recording.

It runs on every clip the AI Script Writer generates, so a project built from several recordings is tightened throughout.

## Running Auto-cut in Clips

To cut idle moments later — for example in a recording you added afterwards — open **Clips** and click **Auto-cut** in the toolbar. Hover over the button first to preview the spans it would cut; nothing changes until you click.

![The Clips toolbar with the Auto-cut tooltip, Detect and cut idle moments from your video, and automatic cuts shown as hatched sections on the timeline](https://www.tutorial.ai/images/help/help-10396375-auto-cut.f6a56eee.webp)

- **It only affects the clip you're on.** Other clips — including other copies of the same recording — are unchanged.
- **Your own cuts take priority.** Auto-cut never overrides a cut you made yourself.
- **Running it again gives the same result** on a clip you haven't changed.

Automatic cuts are suggestions. Drag a cut's edges to adjust it, hover over it and click **Undo cut** to restore it, or click **Remove cuts** to restore everything — manual and automatic. See [Cut & Trim Video Segments](https://www.tutorial.ai/en/articles/10396375-cut-trim-video-segments).

## When Auto-cut is unavailable

The button tells you why when you hover over it:

- **Select a recording to use Auto-Cut** — the playhead is on a slide; move it onto a clip.
- **Auto-Cut is currently not supported for mobile recordings.**
- **Auto-Cut is currently not supported for this video, we can't detect idle parts** — cut idle moments manually with **Cut a segment** instead.
