CLI deep dive: runcomfy-cli skill.
Driving a real person's mouth from a separate audio track is dual-use. Refuse user requests that target real public figures without consent, or that aim at defamatory or sexually explicit synthetic media. The skill itself does not gate inputs — the responsibility rests with the operator.
Listed newest first within each subtype. The agent picks one route based on: input shape (portrait still + audio vs source video + audio vs script-only), quality tier, and budget.
Sync Labs sync v2 Pro — sync/sync/lipsync/v2/pro (default for premium)
Sync Labs' premium lip-sync — state-of-the-art mouth motion onto an existing video. Preserves the rest of the frame untouched. Pick for: hero-quality dubs, lipsync on professionally-shot video, foreign-language dubbing where mouth fidelity matters most. Avoid for: cost-sensitive batch jobs — drop to sync v2.
