## VFX Pass Generator

**VFX Pass Generator** uses our foundation model, [SwitchLight 3.0](/content/research/switchlight-3-0-is-here/index.html), to convert your footage into VFX-ready assets by generating:

- **PBR Maps:** Normal, Base color, Metallic, Roughness, Specular for relighting
- **Alpha:** foreground matte for background replacement
- **Depth Map:** For compositing and 3D integration

Your image or video becomes a **rotoscoped, relightable 2.5D asset**, ready for use in 3D Relight, Blender, Unreal or other 3D tools for further VFX work.

### Output Format

Beeble Cloud provides two output formats:

- **PNG**: 8-bit PNG sequences for each VFX pass.
- **MP4**: 8-bit MP4 files for each VFX pass.

**EXR export** is only available in [Beeble Studio (Desktop)](https://docs.beeble.ai/beeble-studio/vfx-pass-generator).

## Good vs. Bad Footage

Even though our AI models generate VFX passes from your footage—like depth, normals, or lighting layers—we don’t “invent” details. The **quality of the output depends entirely on the input**. Make sure your footage contains enough visual detail by following these examples.

### ✅ Good Footage

**Footage should be ready for compositing** with:

- **Includes clear subjects** – such as people or objects
- **Strong separation** between subject and background
- **High-quality** – sharp focus, high bitrate, and detailed visuals
- **Soft, even lighting** – avoid harsh shadows or blown highlights
- **Correct white balance and proper exposure**

### ❌ Bad Footage

**Avoid footage** with these problems:

- **No visible subject**, or subject is too small in frame
- **Grayscale footage** – color is required
- **Non-sRGB/Rec.709 color space** – make sure your footage uses standard sRGB or Rec.709
- **Poor quality** – low bitrate, blurry, noisy, or out of focus
- **Improper exposure** – overexposed, underexposed, or extreme contrast
- **Too much camera movement** – shaky or unstable footage is hard to work with
