Record TTS, generate product I2V, lay it under the voice, then caption. A talking head is optional.
Faceless UGC is B-roll under a voice. A generated face is still a talking head, not a faceless cut.
A-roll is the spine of the cut — usually a person speaking — not B-roll, and not OpenAI Astra's rollout.
