# Background Removal

Background Removal creates a transparent cutout from a still image. Use it when you want to keep the main subject and remove everything behind it.

This is the image workflow for product cutouts, portrait graphics, thumbnail subjects, stickers, overlays, and design assets. If you need to remove the background from a moving video, use Studio Rotoscope instead.

{% hint style="info" %}
**Background Removal answers: "What should stay in this image?"** The result is usually a transparent PNG that can be placed over another background, graphic, frame, or Premiere composition.
{% endhint %}

### What This Tool Is For

Use Background Removal when you want to:

* Create a transparent product cutout.
* Isolate a person, face, object, logo, animal, car, prop, or graphic.
* Make a thumbnail subject easier to composite.
* Remove a plain or distracting background from a still image.
* Build stickers, overlays, lower-third graphics, or social assets.
* Prepare a subject for Canvas Editor, Image-to-Image, Photoshop, Premiere, or another design tool.

Use a different workflow when:

<table><thead><tr><th width="392">You want to...</th><th>Use instead</th></tr></thead><tbody><tr><td>Remove a background from video</td><td>Studio Rotoscope</td></tr><tr><td>Remove one object while keeping the original background</td><td>Image-to-Image or Canvas Editor</td></tr><tr><td>Replace the background with a new scene</td><td>Image-to-Image or Canvas Editor after creating the cutout</td></tr><tr><td>Make a controlled local edit</td><td>Canvas Editor</td></tr><tr><td>Upscale the final cutout</td><td>Image Upscaling</td></tr></tbody></table>

### Two Background Removal Paths

Chat Video Pro can route background removal in two main ways.

#### Automatic Background Removal

Use this for normal requests like:

```
Remove the background.
```

```
Make this transparent.
```

```
Create a cutout PNG.
```

Best for:

* One clear subject.
* Product photos.
* Portraits.
* Simple or medium-complexity backgrounds.
* Fast transparent PNGs.

This path uses Bria background removal to detect the main subject and remove the background automatically.

#### Subject-Specific Isolation

Use this when the image has multiple subjects or the app needs to know exactly what to keep.

```
Keep only the red sneaker and make everything else transparent.
```

```
Isolate the person on the left.
```

```
Remove the background, keep only the blue car.
```

Best for:

* Multiple people or objects.
* Busy scenes.
* Product groups where only one item should remain.
* Images where the main subject is ambiguous.

This path uses SAM 3 subject isolation for still images. Your wording matters because the model uses the subject description to decide what stays.

***

### How To Use It

1. Attach or upload an image.
2. Type a background removal request.
3. Be specific if there are multiple possible subjects.
4. Generate the result.
5. Use the transparent PNG in your edit, thumbnail, design, or composite.

If you only say `remove background`, Chat Video Pro tries to keep the main subject. If that is not the subject you wanted, run it again with a clearer `keep only...` prompt.

### Image Background Removal vs. Studio Rotoscope

Background Removal and Rotoscope both create cutouts, but they work on different media.

<table><thead><tr><th width="370">Need</th><th>Use</th></tr></thead><tbody><tr><td>Transparent PNG from a still image</td><td>Background Removal</td></tr><tr><td>Transparent moving subject from video</td><td>Studio Rotoscope</td></tr><tr><td>Product or portrait cutout</td><td>Background Removal</td></tr><tr><td>Presenter, dancer, product demo, or moving foreground subject</td><td>Studio Rotoscope</td></tr><tr><td>One static frame from Premiere</td><td>Frame Capture, then Background Removal</td></tr><tr><td>A full video clip with transparency</td><td>Studio Rotoscope</td></tr></tbody></table>

The practical rule: **Background Removal is for images. Rotoscope is for video.**

***

### Best Source Images

Background Removal works best when the subject is easy to understand.

Good source images usually have:

* A clear foreground subject.
* Enough contrast between subject and background.
* Good lighting.
* Clean edges.
* Enough resolution to see hair, product details, or fine shapes.
* Minimal motion blur.

Harder source images include:

* Hair against a similar-colored background.
* Transparent glass, smoke, mesh, lace, or reflective objects.
* Crowded scenes with multiple possible subjects.
* Low-resolution screenshots.
* Subjects partly hidden behind other objects.

For difficult images, use a subject-specific prompt.

***

### Prompt Examples

#### Product Cutout

```
Remove the background and keep only the product. Make everything else transparent.
```

Good for e-commerce images, product graphics, thumbnails, ads, and catalogs.

#### Portrait Cutout

```
Remove the background, keep the person, and preserve the hair edges as cleanly as possible.
```

Good for headshots, thumbnails, creator graphics, social posts, and presenter overlays.

#### Specific Subject In A Busy Scene

```
Keep only the woman in the red jacket and make everything else transparent.
```

Good when the image contains multiple people or objects.

#### Logo Or Graphic Isolation

```
Isolate the logo and make the rest of the image transparent.
```

Good for design assets, overlays, and branded graphics.

### Common Workflows

#### Quick Transparent Cutout

1. Attach the image.
2. Type: `Remove the background.`
3. Generate the transparent PNG.
4. Use it in your edit or design.

Best for clear portraits, products, or simple subjects.

#### Subject-Specific Cutout

1. Attach the image.
2. Describe exactly what should remain.
3. Generate the cutout.
4. Review the edges and subject choice.

Example:

```
Keep only the black camera on the table and make everything else transparent.
```

Best for busy images or multiple-subject scenes.

#### Cutout Then Composite

1. Remove the background from the subject image.
2. Open Canvas Editor or Image-to-Image.
3. Place the cutout over a new background or prompt a new scene.
4. Match lighting, shadows, and scale.

Best when you want a polished creative composite instead of a simple transparent asset.

#### Cutout For Thumbnail Design

1. Remove the background from the person, product, or object.
2. Place the cutout over a bold thumbnail background.
3. Add title text manually or with Thumbnail Mode.
4. Keep the silhouette large and readable.

Best for YouTube thumbnails, social graphics, and ad creatives.

### Best Practices

#### Be Specific When There Are Multiple Subjects

If the image has several people or products, do not only say `remove background`. Say `keep only the person on the left` or `keep only the red shoe`.

#### Use Cutouts As Building Blocks

A clean transparent subject can be reused across many designs: thumbnails, ads, lower thirds, social posts, title cards, and Premiere composites.

#### Do Not Use Background Removal For Object Erasing

If you want to remove an object and keep the original background, that is an image editing/inpainting task. Use Canvas Editor or Image-to-Image.

#### Check Edges Before Final Design

Look closely at hair, hands, product edges, transparent materials, and shadows. If the edge is rough, try a higher-quality source or a more specific subject prompt.

#### Upscale After The Cutout Is Approved

If the cutout is correct but too small, use Image Upscaling after the background removal result is approved.

***

### Troubleshooting

#### The Wrong Subject Was Kept

Use a subject-specific prompt:

```
Keep only the person wearing the yellow jacket and make everything else transparent.
```

#### The Background Was Not Fully Removed

Try a clearer prompt like `make the entire background transparent` or use a higher-quality image with better contrast.

#### The Edges Are Rough

Use a sharper source image, avoid heavy blur, and make sure the subject is well lit. Fine hair, glass, mesh, and shadows are naturally harder.

#### It Removed Part Of The Subject

Describe the subject more completely. For example: `keep the entire person including hair, hands, and shoes.`

#### I Need This For Video

Use Studio Rotoscope. Background Removal is for still images, while Rotoscope tracks a selected subject through a moving video clip.
