# Background removal and upscaling
Part of the doc set: [Media Studio](https://phatdev.net/en/docs/media-studio.md)
> Multi-engine background removal with a quality check, UltraSharpV2 upscaling and TinyPNG compression.
## Background removal
Creates a transparent PNG from a product photo. Engines are tried in order, and a poor result automatically falls through to the next engine:
1. **rembg (isnet)** - fast and clean on most manufacturer photos.
2. **macOS Vision** - native, with crisp edges.
3. **Background-color cut** - keeps everything inside the laptop's outline, so a white screen or a bright logo is never punched out.
4. **Photoshop Select Subject** (for banners) - runs in the background and closes Photoshop by itself after 30s.
### Quality check (since v1.13.2)
A cut-out is treated as failed when it **loses more than 6% of the laptop body**, has an **enclosed hole** inside the body, **breaks into several pieces**, or is almost empty or completely filled. If every engine fails, the video scene switches to a different image. In a test of 23 images, all 5 images where rembg punched holes were replaced with a clean version.
Background removal: rembg or macOS Vision, exported as a transparent PNG
## Upscaling
| Engine | Use when |
|---|---|
| **UltraSharpV2** *(default)* | Any image: Upscale tab, 2K/4K/8K export, automatic 2× upscale after generation. Beat Real-ESRGAN on **10 of 10** test images (PSNR +2.7 to +4.9 dB) and preserves keycap and chart text correctly |
| **Real-ESRGAN** | Automatic fallback when UltraSharpV2 fails |
| **Lanczos** | Quick resize without AI (`engine: "lanczos"`) |
| Photoshop Firefly | Optional - costs Adobe credits, and falls back to Real-ESRGAN on error |
Target sizes: `1080`, `2048`, `2k`, `4k`, `8k` or any custom pixel value.
## Image compression
Every export button includes **TinyPNG compression**; the app rotates between several keys, counts usage per month and balances the load.
