What do the vendors say to do for character and scene consistency (reference images, keyframes, seeds, character assets), and where do their recommendations conflict or limit the technique?

Vendors give different recipes. Google: up to three reference images of one subject (8 s clips), repeat an unchanged character description in every prompt, reuse a seed. Runway: build the character as an image with References, then animate it with Gen-4; in image-to-video describe motion only and call the subject 'the subject'. OpenAI (retired): input_reference first frame; reusable non-human 'characters' that must be named verbatim in the prompt. Luma: Ray3.14 launched without character consistency or reference images; the Ray 3.2 API offers up to 64 keyframes. Kling: a 'master' image, start/end frames, and subject consistency in 3.0 image-to-video. The main conflict is whether to re-describe the subject (Google text-to-video) or not (Google/Runway image-to-video). Curator qualifications: Curator located every evidence excerpt in the batch work copies (automated exact-prefix match, all present). The re-describe vs do-not-re-describe advice is mode-specific (text-to-video vs image-to-video), as the candidate says. Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
