WHAT YOU CHANGE: TWO PHOTOS OF PEOPLE, ONE PRODUCT PHOTO, AND FOUR SLOTS IN THE VIDEO PROMPT ([PRODUCT], [BEFORE], [USE], [AFTER]). NOTHING ELSE. Upload a photo of two people (anyone, one photo each) and one clean photo of @product, all at least 300 px on each side. Steps 1 and 2 turn the two photos into character sheets that hold the faces, step 3 turns the product photo into a three-view product map, step 4 renders the film with both character sheets, the product map and the original photo attached as references. Before firing, answer four questions and paste the answers into the four [SLOTS] of the video prompt (each slot explains itself and carries a mascara example): 1) PRODUCT: what is it, in three words? 2) BEFORE: what does the close-up show before anyone uses it? 3) USE: what does the person do with it, in one sentence? 4) AFTER: what has visibly changed? The same BEFORE answer also goes into the two character sheet prompts, so the characters start in the before state. Everything else stays as written. Two rules: never describe an effect that leaves a face (flash, gust, glow), Seedance renders it as mist; and keep six stages, more than that in 15 seconds collapses into a calm two-shot.
