Convert HDR video (iPhone HLG / Dolby Vision HEVC MOV) to proper SDR Rec.709 with Apple's tone mapping, keeping the best colors, rotation, audio and metadata. Use when footage looks washed out/blown out in CapCut, TikTok or other SDR tools, or when asked to make HDR files non-HDR. Optionally applies a grading LUT in the same encode.

Works with any agent that supports SKILL.md skills.

What this skill can do

We found nothing in the files we read that matches our rules. That does not prove the skill is safe: see the limits of static scanning.

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'hdr-to-sdr' ] || [ -L ~/.agents/skills/'hdr-to-sdr' ]; then echo 'A skill folder named hdr-to-sdr already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/yspreen/dotfiles' "$d" && git -C "$d" checkout --quiet '87cc1bc320b3708985f95b026b4d5a2a50dfea4b' -- '.agents/skills/hdr-to-sdr' && mkdir -p ~/.agents/skills && cp -R "$d"/'.agents/skills/hdr-to-sdr' ~/.agents/skills/'hdr-to-sdr' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'hdr-to-sdr' ~/.claude/skills/'hdr-to-sdr' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
