The mouth movements of a speaking subject do not match the speech in the clip's own audio, even though picture and audio are aligned on the timeline. Also known as Lip-sync mismatch. A form of failure mode in cinematography.
Within Numonic's Cinematography vocabulary, Lip-sync drift sits under failure mode, alongside related concepts such as Audio-video coupling, Blank render, and Drift inheritance.
Numonic captures failure mode like Lip-sync drift as structured metadata, so every take stays linked to the prompt and settings that produced it.
Numonic captures the prompt, seed, and node graph behind each ComfyUI generation automatically, so the result you nailed today is still reproducible next month.
