Board-game crowdfunding trailer from box, minis and cards, Wan 3.0

Send ten photos of the game, such as the box front, three miniatures and six cards, as input_references to wan-3.0 and ask for a 15-second trailer. On Sume that is 15 x $0.10 x 1.25 = $1.875, rounded up to $1.88 at 720p. Expect the box shape and miniature silhouettes to carry across the clip better than any printed text, because the vendor lists on-screen text accuracy as still improving.

Pick the ten references

• One straight-on box front and one angled box shot.
• Three miniatures, photographed against a plain background at the angle you want to see them.
• Four card faces chosen for art, not for rules text.
• One shot of the board or play area.

Prompting without tag syntax

Morphic's page says labelling each reference in the prompt matters as much as supplying it. Sume's docs describe references as visual guidance and do not define a tag or numbering syntax, so describe each reference by what it looks like: the dragon miniature with the red base, the box with the silver crest. A trailer prompt can run as a short arc: box on a table, camera moves to the miniatures, cards fan out, hands move pieces on the board.

Wan 3.0 accepts 10 reference images on Sume, so a game with more components needs a selection or a second clip.

Where the text will be wrong

Card text, rule numbers and the logo on the box are the parts most likely to be redrawn. Plan for it: keep the generated clip text-free by asking for blank card backs and no captions, then place the real title card, rewards and campaign URL in an editor. Sume's timeline docs take Sume-hosted clips, so the end card can be joined to the clip afterwards.

Check each miniature against the photo. A backer will notice if a figure's weapon changes hands.

Trailer structure for a 15-second cut

Fifteen seconds is enough for three beats of five seconds. Beat one is the box on a table with the camera pushing in. Beat two is the miniatures lined up, then one stepping forward. Beat three is the cards and board, ending on a wide shot with room for a title overlay. If the campaign wants a 30-second spot, the price doubles to $3.75 at 720p, and the extra time needs more story, not more products.

Wan 3.0 generates audio by default in the catalog entry (generate_audio is optional), so decide before submitting whether you want the model's sound bed or your own music. A trailer usually wants its own track and the real voice-over, so set generate_audio to false when you plan to replace it and avoid choosing between two soundtracks later.

Run order

• Draft at 480p (15 s is $0.94) and review the references that were ignored.
• Fix the prompt, then render 720p ($1.88) for review.
• Render 1080p ($3.75) only for the clip that goes on the campaign page.
