lipsync

80 / 100 · Low risk

By hashgraph-online/awesome-codex-plugins (GitHub) · media · 1,568 stars · scanned at commit 3e1e6b2

Lip-sync one existing video of a real person to new speech with sync. labs (sync.so), so their mouth matches a new voiceover, re-recorded take, song, or a typed script that sync. voices. Accepts local files, URLs, sync. assets and YouTube, TikTok, Instagram or Facebook links. Use whenever the user wants to lipsync, lip sync or sync lips, match mouth movement to audio, "make him say…", replace the audio in a talking-head clip, or sync a clip to a song, even if they don't say "lipsync". Not for A…

Works with any agent that supports SKILL.md skills.

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

if [ -e ~/.agents/skills/'lipsync' ] || [ -L ~/.agents/skills/'lipsync' ]; then echo 'A skill folder named lipsync already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/hashgraph-online/awesome-codex-plugins' "$d" && git -C "$d" checkout --quiet '3e1e6b20ffc28f42923e391f29f075c424e19e64' -- 'plugins/synchronicity-labs/skills/skills/lipsync' && mkdir -p ~/.agents/skills && cp -R "$d"/'plugins/synchronicity-labs/skills/skills/lipsync' ~/.agents/skills/'lipsync' && 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/'lipsync' ~/.claude/skills/'lipsync' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
