name: xeon-smartupscale_v2
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 <skill_dir>/install.sh
bash <skill_dir>/smartupscale.sh <input.mp4>

Optional custom output path:

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.
