A Python CLI tool that removes backgrounds from videos using `rembg` and `OpenCV`. It supports full video export, transparent frame extraction, animated WebP / GIF generation, and MatAnyone foreground+alpha pair conversion.

It can also run `MatAnyone 2` through the published [`matanyone2-runtime`](https://pypi.org/project/matanyone2-runtime/) package when you provide a Python executable where `matanyone2-runtime>=0.2.0` is installed.

## ✨ Features

- Split a video into frames, remove the background, and rebuild it as a video
- Export transparent `webp` / `png` frames at fixed intervals
- Generate transparent animated `webp` / `gif`
- Convert MatAnyone `*_fg.mp4` + `*_alpha.mp4` pairs into transparent `webp` / `gif`
- Clean green-screen fringes from MatAnyone edges before applying transparency
- Replace the removed background with a solid color or background image
- Switch between `isnet-general-use`, `u2net`, `u2netp`, `u2net_human_seg`, and `silueta`

## 📋 Requirements

- Python 3.10 or later
- FFmpeg is not required
- The model is downloaded on first run

## 🛠️ Install

### From PyPI

```bash
pip install video-background-remover
```

### Local development

```bash
pip install -e ".[dev]"
```

### With `uv`

```bash
uv sync --extra dev
```

## 🚀 Quick Start

### Launch the Gradio WebUI

The repository now includes a Gradio 6 WebUI that mirrors the MatAnyone Video/Image workflow, adds a `CLI Export` tab for the current CLI feature set, and provides post-export helpers for animated `webp`, animated `gif`, zipped transparent frame exports, flattened `mp4`, and transparent `webm`.

Recommended `uv` launch command when you already have `D:\Prj\MatAnyone` set up:

```powershell
uv run --python D:\Prj\MatAnyone\.venv\Scripts\python.exe -m video_background_remover_cli.webui --port 7860
```

You can also launch the repository wrapper script through `uv`:

```powershell
uv run --python D:\Prj\MatAnyone\.venv\Scripts\python.exe .\webui.py --port 7860
```

If you installed this project as a package, you can use:

```powershell
video-background-remover-webui --port 7860
```

Notes:

- The WebUI still reuses the MatAnyone runtime environment so the original interactive SAM/matting workflow stays available.
- The `CLI Export` tab covers the current CLI feature surface for `rembg`, `--backend matanyone`, and `--matanyone` foreground+alpha pair conversion.
- Image outputs are saved as `png` and `webp`.
- Video outputs keep the original foreground/alpha pair and can then be exported as `webp`, `gif`, `png` frame ZIPs, `mp4`, or `webm`.

### MatAnyone2 Tile WebUI

`MatAnyone2 Tile` is the WebUI route for 2x2 or 3x3 tiled videos. It runs the usual MatAnyone masking flow, keeps the combined foreground/alpha pair, and then splits the finished result into one animated `webp` and one animated `gif` per tile.

- Fresh runs and resume runs are grouped under `output/webui/matanyone2_tile/<run-dir>/`.
- Split animations are written under `tiles_2x2/` or `tiles_3x3/`.
- The auto-detected resume picker stays focused on Tile runs only, but you can still paste any absolute run directory or `*_fg.mp4` path when you need to resume from somewhere else.

Example output layout:

```text
output/webui/matanyone2_tile/<run-dir>/
├─ <source>.mp4_fg.mp4
├─ <source>.mp4_alpha.mp4
├─ metadata.json
└─ tiles_3x3/
   ├─ tile_01_animated.webp
   ├─ tile_01_animated.gif
   └─ ...
```

Sample tile assets from the documented 3x3 run:

| Animated WebP tile | Animated GIF tile |
| --- | --- |
| <img src="docs/public/media/matanyone2_tile/tiles_3x3/tile_01_animated.webp" alt="MatAnyone2 Tile sample WebP tile" width="180"> | <img src="docs/public/media/matanyone2_tile/tiles_3x3/tile_01_animated.gif" alt="MatAnyone2 Tile sample GIF tile" width="180"> |

### 1. Export a video with a white background

```bash
video-background-remover assets/onizuka_idle_motion.mp4 output/output_white.mp4 --bg-color white
```

### 2. Export a transparent animated WebP

```bash
video-background-remover assets/onizuka_idle_motion.mp4 output/output_animated.webp --animated webp --webp-fps 10
```

### 3. Export transparent frames every second

```bash
video-background-remover assets/onizuka_idle_motion.mp4 output/frames --interval 1 --format webp
```

### 4. Convert a MatAnyone pair into a transparent WebP

```bash
video-background-remover assets/MatAnyone --matanyone output/matanyone.webp
```

### 5. Export a compact MatAnyone preview

```bash
video-background-remover assets/MatAnyone --matanyone output/matanyone_5fps_300.webp --webp-fps 5 --size 300x300
```

### 6. Run MatAnyone directly from the PyPI package

Install `matanyone2-runtime>=0.2.0` into a Python 3.10 environment first, then point this CLI at that interpreter:

```bash
video-background-remover input.mp4 output/matanyone.webp --backend matanyone --matanyone-python C:\path\to\python.exe --animated webp
```

## 💡 Usage

```bash
video-background-remover INPUT [OUTPUT] [options]
```

If you are running directly from the repository, `python main.py ...` and `python -m video_background_remover_cli ...` still work.

If `OUTPUT` is omitted, the CLI auto-creates `./output/<input-file-name>_<timestamp>/` and saves the result there using a name derived from the input file.

### Full video export

```bash
video-background-remover input.mp4 --bg-color white
video-background-remover input.mov --format mp4 --bg-color white
video-background-remover input.mp4 --size 300x300 --bg-color white
video-background-remover input.mp4 output.mp4 --bg-color white
video-background-remover input.mp4 output.mp4 --bg-image background.jpg
video-background-remover input.mp4 output.mp4 --fps 30
```

Regular video output does not preserve alpha transparency. If you want a visible background, pass `--bg-color` or `--bg-image`.

### Transparent frame export

```bash
video-background-remover input.mp4 --interval 0.5 --format webp
video-background-remover input.mp4 --interval 1 --format webp --size 300x300
video-background-remover input.mp4 output/frames --interval 0.5 --format webp
video-background-remover input.mp4 output/frames --interval 1 --format png
```

When `--interval` is set, `OUTPUT` is treated as a directory name instead of a file path.

### Animated WebP / GIF export

```bash
video-background-remover input.mp4 --animated webp
video-background-remover input.mp4 --animated webp --size 300x300
video-background-remover input.mp4 output/output_animated.webp --animated webp
video-background-remover input.mp4 output/output.gif --animated gif --webp-fps 8
video-background-remover input.mp4 output/output --animated both --webp-fps 8 --max-frames 120
```

With `--animated both`, the tool writes both `.webp` and `.gif` using the same base name.

### MatAnyone foreground + alpha pair export

Use `--matanyone` when `INPUT` is either:

- a directory containing one `*_fg.*` file and its matching `*_alpha.*` file
- a foreground file such as `clip_fg.mp4`

Examples:

```bash
video-background-remover assets/MatAnyone --matanyone output/matanyone.webp
video-background-remover assets/MatAnyone --matanyone output/matanyone_2fps_300.webp --webp-fps 2 --size 300x300
video-background-remover assets/MatAnyone --matanyone output/matanyone_5fps_300.webp --webp-fps 5 --size 300x300
video-background-remover assets/MatAnyone --matanyone output/matanyone_10fps_300.webp --webp-fps 10 --size 300x300
video-background-remover assets/MatAnyone/grok-video-e3987723-09fa-4c1e-a054-eb82a7c13e8f.mp4_fg.mp4 --matanyone output/matanyone.gif --animated gif
video-background-remover assets/MatAnyone --matanyone output/matanyone_10fps_300.gif --animated gif --webp-fps 10 --size 300x300
video-background-remover assets/MatAnyone --matanyone output/matanyone.mp4 --bg-color white
video-background-remover assets/MatAnyone --matanyone output/matanyone_frames --interval 0.5 --format png
```

Notes:

- Transparent alpha is preserved for animated `webp`, animated `gif`, and interval frame export.
- In `--matanyone` mode, `.webp` output uses the provided alpha mask to build transparent frames.
- The MatAnyone pipeline removes the baked green matte from semi-transparent edges before export.
- `--size 300x300` with `--webp-fps 5` is a good default for compact previews.
- Regular `mp4` does not preserve alpha. The tool composites transparent pixels onto `--bg-color`, `--bg-image`, or black when neither is specified.

#### Green Fringe Cleanup Preview

The MatAnyone exporter keeps a dedicated edge-cleanup pass for baked green matte contamination. This comparison shows four cleanup strengths on `assets/MatAnyone_cat3`; `strong` and `trim` push hardest against visible green spill, while `soft` keeps the fullest whiskers and fur edges.

The residual map below highlights the small edge pixels where green is still stronger than red/blue after cleanup. It is useful when deciding whether to preserve a thin whisker edge or trim alpha a bit more aggressively.

- When you compare cleanup candidates, encode the profile or tuning values in the filename, for example `MatAnyone_cat3_trim_sm0_gb4_rb60_as180_am120_md255.webp`.
- The token convention used here is `sm=spill margin`, `gb=green bias`, `rb=red boost`, `as=alpha spill`, `am=alpha matte`, and `md=max drop`.

### MatAnyone package backend

Use `--backend matanyone` when you want this project to invoke the published `matanyone2-runtime` package and generate the foreground and alpha pair for you.

Examples:

```bash
video-background-remover input.mp4 output/out.webp --backend matanyone --matanyone-python C:\path\to\python.exe --animated webp
video-background-remover input.mp4 output/out.gif --backend matanyone --matanyone-python C:\path\to\python.exe --animated gif --positive-point 320,180
video-background-remover input.mp4 output/out.mp4 --backend matanyone --matanyone-python C:\path\to\python.exe --bg-color white
```

Notes:

- `--matanyone-python` should point to a Python where `matanyone2-runtime>=0.2.0` is installed.
- `--matanyone-root` is only a fallback for discovering a sibling `.venv`; it is not required for normal PyPI usage.
- The package backend imports `matanyone2.run_pipeline()` inside the target Python instead of shelling out to the package CLI.

## 📝 Notes

- The initial model load can take some time
- Long videos exported as `--animated gif` can become large
- If you need transparency, prefer `--animated webp` or `--interval` output instead of regular video export
- If you already have MatAnyone foreground and alpha videos, prefer `--matanyone` because it skips `rembg` inference entirely
- MatAnyone exports usually look good around `300x300` with `5fps`, while `10fps` is smoother but larger
