video-to-4k SKILL.md skillA

This file is byte-identical to the first copy the registry indexed. Same content hash, so the same checks give both the same grade.

video-to-4k from godot-fun/gai is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned

mdr add godot-fun/gai/video-to-4k@git:20261101.d8fbf4c

Pins git:20261101.d8fbf4c in mdr.lock. Pin the fingerprint instead.

Upscales a single low-resolution video to 4K with Video2X (Real-ESRGAN), then encodes to unified 3840×2160 H.265 Main10 40Mbps + AAC 320kbps MP4. Source frame rate is preserved (no fps=60 duplication, no RIFE). Already-4K sources skip Video2X and go straight to FFmpeg. Use when the user wants video-to-4k, 4K upscale, UHD export, Video2X, Real-ESRGAN, H.265 Main10, or convert an SD/HD clip to 4K.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Video to 4K

Convert a supported video to a **unified 4K master**:

| Spec | Value |
|------|-------|
| Resolution | 3840×2160 |
| Frame rate | **Source fps kept** (no `fps=` filter, no RIFE) |
| Video | H.265 Main10 (`libx265`, `yuv420p10le`) |
| Video bitrate | 40 Mbps |
| Audio | AAC 320 kbps |
| Container | MP4 (`.mp4`, `hvc1` tag) |

## Pipeline

1. **Probe** with ffprobe (width, height, fps, audio).
2. **Already 4K?** (`width ≥ 3840` and `height ≥ 2160`) → skip Video2X.
3. **Below 4K** → [Video2X](https://github.com/k4yt3x/video2x) Real-ESRGAN upscale (scale 2 or 4) to intermediate under `video-to-4k/upscaled/`.
4. **Always** FFmpeg final encode → `video-to-4k/` at the unified specs above.

## Rules

When this skill applies, read and follow [dependency-manager](../dependency-manager.md) — run scripts as documented, install missing tools into `.dependency/`.

- Run `convert.py` through **`.dependency/python/python`**. Never use host `python` / `ffmpeg` / `video2x`.
- **Never overwrite sources.** Outputs go under `video-to-4k/` (final) and `video-to-4k/upscaled/` (Video2X intermediate).
- Use the bundled script — do not hand-write equivalent `video2x` / `ffmpeg` commands.

How to install

The exact contents, by fingerprint

mdr add godot-fun/gai/video-to-4k@sha256:1bc0f1869660cd90

The line at the top of this page pins the label git:20261101.d8fbf4c, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
