video-4k-normalization SKILL.md skillA

video-4k-normalization from godot-fun/godot-agent 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/godot-agent/video-4k-normalization@git:20261101.d8fbf4c

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

Normalizes a single video clip to unified 3840×2160 60FPS H.265 Main10 40Mbps + AAC 320kbps BT.709 SDR MP4 4K master (FFmpeg re-encode, HDR tone-mapped). Use before hard-cut merge when 4K (or near-4K) clips differ in color space, HDR/SDR, fps, or size. Triggers: video-4k-normalization, 4K normalization, video normalization, media conform, unify encode, color conform, tone map HDR, prepare for video-merge, mixed HDR/SDR.

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 4K Normalization

Re-encode a clip to one **merge-safe 4K master** (same delivery specs as
`video-to-4k`, plus **unified BT.709 SDR color**):

| Spec | Value |
|------|-------|
| Resolution | 3840×2160 |
| Frame rate | 60 FPS |
| Video | H.265 Main10 (`libx265`, `yuv420p10le`) |
| Video bitrate | 40 Mbps |
| Audio | AAC 320 kbps |
| Color | **BT.709 / bt709 / tv** (HDR → tone-mapped SDR) |
| Container | MP4 (`.mp4`, `hvc1` tag) |

**Not** AI upscaling — use [`video-to-4k`](../video-to-4k/SKILL.md) first when
SD/HD needs Real-ESRGAN quality. This skill uses FFmpeg `scale` + encode only.

## Why

Hard-cut [`video-merge`](../video-merge/SKILL.md) is stream-copy. Mixed
**HDR (BT.2020 + PQ)** and **SDR (BT.709)** clips look fine alone, but after
concat the player often applies the first clip's HDR tags to later SDR →
oversaturated cuts. Normalization unifies pixels **and** color tags first.

## Rules

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

- Run `normalize.py` through **`.dependency/python/python`**. Never use host `python` / `ffmpeg`.

How to install

The exact contents, by fingerprint

mdr add godot-fun/godot-agent/video-4k-normalization@sha256:71f02edd4f9d3109

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.
