video-4k-normalization skillA
video-4k-normalization is agent-read markdown (skill) from godot-fun/godot-agent: 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..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns 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 [skill-dependency-manager](../skill-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
mdr add godot-fun/godot-agent/video-4k-normalization@git:20260918.a3d4acfmdr add godot-fun/godot-agent/video-4k-normalization@sha256:dca5709f7e7c1bb6Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
