description: Experiment-faithful 1080p upscaler for Intel Xeon CPUs. Decodes frames, resizes them in memory to 480x270 with lanczos, then runs Real-ESRGAN general-x4v3 x4 in OpenVINO CPU mode with a BF16 hint.

## Goal

Reproduce the exact 1080p experiment pipeline:

1. Decode source frames
2. In-memory `lanczos` -> `480x270`
3. Real-ESRGAN general-x4v3 x4 -> `1920x1080`
4. Encode with H.264 `medium`, `crf 15`

## Usage

```bash
bash <skill_dir>/install.sh
bash <skill_dir>/smartupscale.sh <input.mp4>
```

Optional custom output path:

```bash
bash <skill_dir>/smartupscale.sh <input.mp4> -o <output.mp4>
```

## Packaging Notes

- `model/realesr-general-x4v3_480x270.xml` and `.bin` are vendored for the fixed 1080p path.
- No dynamic export path is included. This package stays on the fixed experiment model.
- For ClawHub publishing, the raw `.bin` weights can be omitted from the package and restored from `model/realesr-general-x4v3_480x270.bin.b64` or chunked `model/realesr-general-x4v3_480x270.bin.b64.part-*` files during `install.sh`.

## Output

- Final video: `1920x1080`, H.264 `medium`, `crf 15`
- Audio: copied from source when possible
- Lanczos pre-scale is done in memory before inference; no encoded intermediate stage is produced.
