The editorial job is the same regardless of how the face was made. Someone addresses the viewer, the mouth has to match the words, and the cut is built around that performance. A-roll is the name of that spine. B-roll covers it. Voiceover is the other door: a read under picture that does not need a mouth. Lipsync is the generate that makes a mouth agree with a track. Mixing them is how a product demo grows a presenter it did not need, or a VO gets burned in as subtitles with no audio.
Generated talking heads are AI UGC when the brief is a peer in the feed, and they are a YPP problem when the brief is a fake expert on health, legal, finance, or politics. Inauthentic content is the policy name for that third bucket. A labelled avatar walking a skincare routine is a format choice. A labelled avatar diagnosing is a monetisation kill. Real creators still win when the product has to be handled or the audience already knows the face.
Faceless channels exist to avoid this shot. That is a different format, not a failed talking head. If the spine is a person, film them or lipsync them on purpose. If the spine is a product, do not invent a host to 'make it a video.'
In practice
- Decide whether the spine is a person or a product before you pick a model.
- If a mouth on screen has to match, that is lipsync, not a voiceover laid under a still.
- Do not put a synthetic presenter on expert advice in a YPP niche and rely on the AI label to save it.
The mistake to avoid
Generating a photoreal presenter because you needed a read. Voiceover does not require a face.
Where you will run into it
- Lipsync a Photo or Video to Audio — One photo, one audio file, one talking clip.
- Add a Voiceover to a Video — Type the script. Get a narrated video back.
- AI Avatar Generator — Pick a face, hand it a script, get a presenter.
- AI UGC Video Generator — UGC ads at the speed and price of a prompt.

A-roll
A-roll is the primary footage a cut is built around — usually a person speaking — as distinct from B-roll that covers it and from a generate that tries to be both.
Lipsync
Lipsync meaning: an AI model moves a face's mouth to match an audio track, so the words look spoken by that face instead of dubbed over the top.
Faceless channel
A faceless channel publishes without showing the creator's face — voiceover, screen, b-roll, or a generated presenter instead of a to-camera host.
Voiceover
A voiceover is a spoken track laid under picture, rather than lipsync that drives a mouth or a caption track that visualises speech.
Hook rate
Hook rate meaning: the share of people shown a video who are still watching a few seconds in. It grades the opening, not the body.
